Ring 2

Filme in 50 Worten

Angst. Anspannung. Ring 2 ist die würdige Fortsetzung von Ring. Wie soll ich sagen? Kinder sind der größte Horror.
Wir tauchen tiefer in die Geschichte von Samara ein, und wieder sehen wir, wie Rachel um ihren Sohn kämpft. Der Mut, den sie dabei aufbringt, grenzt ans unglaubwürdige - bis man sich vor Augen hält, dass sie um das blanke Leben ihres Kindes kämpft.

Ring ist bislang der einzige Horror-Film, der mir überhaupt gefiel - und ich habe so manchen gesehen. Es ist insbesondere, der einzige, der Horror herberief. Nun gesellt sich Ring 2 dazu.

So spannend, dass ich ganz verspannt im Kino saß, und danach echt verspannt war...

Risiko Alter

Die Bundesregierung hat ein kleines Heftchen veröffentlicht, mit dem zauberhaften Titel "agenda 2010 - Deutschland bewegt sich". Ich hatte mir es heute, aus Interesse und auch aus mangelnder Alternative in der Straßenbahn durchgelesen, und fand einiges Interessant. Herrje, wieviel Geld des erarbeiteten Einkommens gar nicht an mich gehen wird! Als unbedarfter Student ahnt man das ja gar nicht, ich werde hoffentlich bald persönlich in den Genuss kommen, die Begriffe Brutto und Netto mit Bedeutung zu füllen.
Aber darum geht es nicht. Auch nicht darum, dass einige sehr nette Ideen drin waren, und einige fehlleitende Informationen und offensichtlich verfälschende Statistiken. Das ist ja üblich, und man sollte das gewohnt sein. Viel erschreckender jedoch führte mir ein kleiner Satz im Glossar die Einstellung der Bundesregierung vor Augen:
"Soziale Sicherungssysteme [...] Damit sind alle Versicherten solidarisch gegen die großen Risiken Alter und Erwerbsminderung [...] abgesichert."
Das Risiko Alter? Auf der Suche nach einer Quellenangabe im Netz stieß ich auf über 300 Treffer, die über das Risiko Alter sprechen.

Meine sehr geehrte Bundesregierung, liebe Herren und Damen Versicherer, lasst Euch hiermit deutlich gesagt sein, dass das Alter meiner bescheidenen Meinung nach kein Risiko ist, sondern vielmehr Ergebnis des offensichtlichen Meisterns zahlreicher vorhergehender Risiken. Mir ist durchaus bewusst, dass für einen Versicherer wie auch für die Bundesregierung, die ja unter anderem für eine Sicherung des Rentensystems zuständig ist, das Alter der einzelnen Personen durchaus ein Risiko ist, doch glauben sie mir, wir, als Alternde, wünschen selten mit so offensichtlichem Zynismus und unüblicher Ehrlichkeit darauf hingewiesen zu werden.
Auf alle, die das Risiko Alter bereit sind einzugehen! (- und das nicht nur ob der zweifelhaften Alternative)

Rollenspiel und Web 2.0

Letzte Woche hielt ich in Wien einen Vortrag auf der Semantics 2006. Danach wurde ich um ein Radio-Interview gebeten, und dabei sprachen wir über das Semantic Web, Web 2.0 und ähnliche Themen -- meine Arbeit halt. Semantic Web, das Web der Daten, Web 2.0, das Mitmach-Web (ganz grob).

Plötzlich aber wechselte die Reporterin das Thema, meinte, ich würde ja auch an Deutschlands beliebtestem Rollenspiel Das Schwarze Auge arbeiten. Ob ich den Zuhörern erklären könnte, was denn Rollenspiel sei. Und da erklärte ich Rollenspiel als Geschichtenerzählen 2.0 -- Geschichtenerzählen zum Mitmachen, wo es darum geht, in der Gruppe eine gemeinsame Geschichte zu erzählen.

Na, wenn das mal keine neue Definition ist.

Rom mit vielen Gesichtern

Man läuft durch Rom, und man sieht, es ist die Stadt der Päpste. Überall finden sich gigantische Marmorplatten, auf denen erklärt wird, dass diese(r/s) Platz / Kirche / Gebäude / Monument / Brunnen / Brücke von Seiner Heiligkeit, P.M. (nicht etwa Prime Minister, sondern Pontifex Maxmimus) Soundso dem Sounsovielten gemacht wurde, im Jahre 12. Das heißt natürlich nicht etwa, dass das Ding knapp 2000 Jahre alt ist, sondern bezeichnet das 12. Jahr seines Papstseins. Es gibt sogar eine riesige Platte auf dem McDonalds gegenüber vom Pantheon, die auf -- Erinnerung ist schwach -- glaube Leo XII. verweist. Das Mc-Symbol ist da deutlich dezenter. Wieviele Fastfoodketten haben das noch?

Dann läuft man weiter, und entdeckt auch, dass Rom die Stadt eines antiken Imperiums ist. Das Kollosseum (gigantisch!), das Forum Romanum, das Pantheon natürlich, das Mausoleum von Kaiser Hadrian, heute Castel St Angelo, die Statuen überall. Atemberaubend.

Dann läuft man weiter, und entdeckt dass es auch die Stadt Berninis, der die Stadt in der Renaissance wieder wachküsste, und sie in eine Stadt der Brunnen verwandelte. Überall fließt Wasser, wohlgemerkt, allesamt Trinkwasser, was vor allem an den heißeren Tagen sehr beliebt ist, das Plätschern, die wunderschönen Parkanlagen (wirklich atemberaubend mit ihren künstlichen Seen und natürlichen Hügeln, und darauf die jahrhundertealten Bäume).

Und dann läuft man weiter, und man sieht, dass es auch die Stadt der Regierung eines modernen Italiens ist. Der Palast des Präsidenten, mit den wohl coolsten Wächteruniformen überhaupt (vergesst die Uniformen der Schweizer Garde, die von einem gewissen Michelangelo designt wurden). Lange, wehende Mäntel, große blitzende Knöpfe, und ein Ritter, der im Eingang steht, weit hinten, im Dunkeln, und sich nie bewegt, auf sein Schwert gestützt, mit einem großen Helm. Denke nicht, dass er gegen einen Bewaffneten mit 'ner Schusswaffe auch nur den Hauch einer Chance hätte, aber er sieht so morsmäßig cool aus!

Und schließlich, nach dem vielen Gelaufe, wird es dunkel, und dann merkt man, dass Rom auch eine Stadt der jungen Leute ist, mit unzähligen Kleinen und manchen Großen Bars, und viel Leben auf der Straße. Rom hat unglaublich viele Gesichter, aber ich nehme an, in einer Stadt mit 2800 Jahren Geschichte sammelt sich halt mit der Zei was an...

Running out of text

Many of the available text corpora have by now been used for training language models. One untapped corpus so far have been our private messages and emails.

How fortunate that none of the companies that train large language models have access to humongous logs of private chats and emails, often larger than any other corpus for many languages.

How fortunate that those who do have well working ethic boards established, who would make sure that such requests are evaluated.

How fortunate that we have laws in place to protect our privacy.

How fortunate that when new models are published also the corpora are being published on which the models are being trained.

What? Your telling me, "Open"AI is keeping the training corpus for GPT-4 secret? The company closely associated with Microsoft, who own Skype, Office, Hotmail? The same Microsoft who just fired an ethics team? Why would all that be worrisome?

P.S.: To make it clear: I don't think that OpenAI has used private chat logs and emails as training data for GPT-4. But by not disclosing their corpora, they might be checking if they can get away with not being transparent, so that maybe next time they might do it. No one would know, right? And no one would stop them. And hey, if it improves the metrics...

SSSW Day 1

Today's invited speaker was Frank von Harmelen, co-editor of the OWL standard and author of the Semantic Web Primer. His talk was on fundamental research challenges generated by the Semantic Web (or: two dozen Ph.D. topics in a single talk). He had the idea after he was asked one day in the cafeteria "Hey Frank, whazzup in the Semantic Web?"

In the tradition of Immanuel Kant's four famous questions on philosophy, Frank posed the four big research challenges:

• Where does the metadata come from?
• Where do the ontologies come form?
• What to do with the many different ontologies?
• Where's the Web in the Semantic Web?

He derived many research questions that arise when you bring results from other fields (like databases, natural language, machine learning, information retrieval or knowledge engineering) to the Semantic Web and not just change the buzzwords, but take the implications that come along with the Semantic Web seriously.

Some more notes:

• What is the semantic equivalent to a 404? How should a reasoner handle the lack of referential integrity?
• Inference can be cheaper than lookup on the web.
• Today OWL lite would probably have become more like OWL DLP, but they didn't know better than

The other talks were given by Asun Gómez-Pérez on Ontological Engineering, and Sean Bechhofer on Knowledge Representation Languages for the SemWeb, pretty good stuff by the people who wrote the book. I just wonder if it was too fast for the people who didn't know about it already, and too repeting for the others, but well, that's always the problem with these kind of things.

The hands-on session later was interesting: we had to understand several OWL ontologies and explain certain inferences, and Natasha Noy helped us with the new Protégé 3.1. It was harder than I thought quite some times. And finally Aldo Gangemi was giving us some exercises with knowledge representation design patterns, based on DOLCE. This was hard stuff...

Wow, this was a lot of namedropping. The social programme (we were hiking today) around the summer school, and the talks with the peers are sometimes even more interesting than the actual summer school programme itself, but this probably won't be too interesting for most of you, and it's getting late as well, so I just call it a day.

SSSW Day 2

Natasha Noy gave the first talk today, providing a general overview on Mapping and Alignment algorithms and tools. Even though I was not too interested in the topic, she really caught my interest with a good and clean and structured talk. Thank for that! After, Steffen Staab continued, elaborating on the QOM approach to ontology mapping, having some really funny slides, but, as this work was mostly developed in Karlsruhe I already knew it. I liked his appeal for more tools that are just downloadable and usable, without having to fight for hours or days just to create the right environment for them. I totally agree on that!

The last talk of the day was from Aldo Gangemi on Ontology Evaluation. As I consider making this the theme of my PhD-thesis - well, I am almost decided on that - I was really looking forward to his talk. Although it was partially hard to follow, because he covered quite a broad approach to this topic, there have been numerous interesting ideas and a nice bibliography. Much to work on. I especially didn't yet see the structural measures he presented applied to the Semantic Web. Not knowing any literature on them, I am still afraid, that they actually fail [SSSW Day 1|Frank's requirements from yesterday]]: not just to be taken from graph theory, but rather to have the full implications of the Semantic Web paradigm been applied to them and thought through. Well, if no one did that yet, there's some obvious work left for me ;)

The hands-on-sessions today were quite stressy, but nevertheless interesting. First, we had to powerconstruct ontologies about different domains of traveling: little groups of four persons working on a flight agency ontology, a car rental service ontology and a hotel ontology. Afterwards, we had to integrate them. Each exercise had to be done in half a hour. We pretty much failed miserably in both, but we surely encountered many problems - which was the actual goal: in OWL DL you can't even concatenate strings. How much data intefration can you do then?

The second hands-on-session was on evaluationg three ontologies. It was quite interesting, although I really think that many of these things can happen automatically (I will work on this in the next two weeks, I hope). But the discussion afterwards was quite revealing, as it showed how differently people think about some quite fundamental issues, the importance they give to structural measures compared to the functional ones. Or, differently said: the question is, is a crappy ontology on a given domain better than a good ontology that doesn't cover your domain of interest? (The question sounds strange to you? To me as well, but well...)

Pitily I had to miss today's social special event, a football match between the students of the Summer School. Instead I had a very interesting chat with a colleague from the UPM, who came here for a talk, and who also wants to make her PhD in Ontology Evaluation, Mari Carmen Suárez de Figueroa. Interesting times are lying ahead.

SSSW Day 3

Yeah, sure, the Summer School for the Semantic Web is over for quite a while now, and here I started to blog about it daily, and didn't manage to get over the first three days. Let's face it: it was too much! The program was so dense, the social events so enjoyable, I couldn't even spare half an hour a day to continue the blogging. Now I want to recap some of my notes and memories I have of the second half of the Summer School. My bad memory be damned - if you want to correct something feel free to do so.

This day's invited speaker was Roberto Basili of the University of Rome. He sketched the huge field of natural language processing, and although he illustrated the possible interactions between lexical knowledge bases and ontologies, he nevertheless made a strong distinction between these two. Words are not concepts. "The name should have no value for defining a concept." This is like "Don't look into URIs" for HLT-people. He made a very interesting point: abductions will become very important in the Semantic Web, as they model human thinking patterns much closer than strict deduction does. Up until this day I was quite against abductions, I discussed this issue very stubbornly in Granada. But Roberto made me aware of a slightly different viewpoint: just sell abductive resolutions as suggestions, as proposals to the user - et voilà, the world is a better place! I will have to think abou this a bit more some day, but he did made me think.

The theoretical sessions and workshops today were packed and strenuos: we jumped from annotations to Semantic Web Services and back again. Fabio Ciravegna of the University of Sheffield's NLP-Group, who created tools like Armadillo and GATE, gave us a thorough introduction to annotations for the Semantic Web and the usage of Human Language Technologies in order to enhance this task. He admitted that many of the tools are still quite unhandy, but he tried to make a point by saying: "No one writes HTML today anymore with a text editor like Emacs or Notepad... or do you?"
All students raised their hands. Yes, we do! "Well, in the real world at least they don't..."

He also made some critical comments on the developments of the Semantic Web: the technologies being developed right now allow for a today unknown ability of collecting and combining data. Does this mean, our technologies actually require a better world? One with no secrets, privacy and spam, because there is no need for such ideas? Is metadata just adding hay to the haystak instead of really finding the needle?

John Domingue's Talk on Semantic Web (Web) Services was a deep and profound introduction to the field, and especially to the IRS system developed by the KMi at Open University. He was defending WSMO valiantly, but due to time constraints pitily skipped the comparison with OWL-S. But he motivated the need for Semantic Web Services and sketched a possible solution.

The day ended in Cercedilla, where we besieged a local disco. I guess the people were hiding, "watch it, them nerds are coming!" ;) The music surprisingly old - they had those funny vinyl albums - but heck, Frank Sinatra is never outdated. But the 80s certainly are...

SSSW Day 4

This day no theoretical talks, but instead two invited speakers - and much social programme, with a lunch at a swimming pool and a dinner in Segovia. Segovia is a beautiful town, with a huge, real, still standing roman aqueduct. Stunning. And there I ate the best pork ever! The aqueduct survived the huge earthquake of Lisbon of 1755, although houses around it crumbled and broke. This is, because it is built without any mortar - just stone over stone. So the stones could swing and move slightly, and the construction survived.
Made me think of loosely coupled systems. I probably had too much computer science the last few days.

The talks were very different today: first was Mike Woolridge of the University of Liverpool. He talked about Multiagent Systems in the past, the present and the future. He identified five trends in computing: Ubiquity, Interconnection, Intelligence, Delegation and Human-orientation.
His view on intelligence was very interesting: it is about the complexity of tasks that we are able to automate and delegate to computers. He quoted John Alan Robertson - the guy who invented resolution calculus, a professor of philosophy - as exclaiming "This is Artificial Intelligence!", when he saw a presentation of the FORTRAN compiler at a conference. I guess the point was, don't mind about becoming as intelligent as humans, just mind at getting closer.
"The fact that humans were in control of cars - our grandchildren will be quite uncomfortable with this idea."

The second talk was returning to the Semantic Web in a very pragmatic way: how to make money with it? Richard Benjamins of iSOCO just flew in from Amsterdam where he was at the SEKT meeting, and he brought promising news about the developing market for Semantic Web technologies. Mike Woolridge was criticizing Richard's optimistic projections and noted that he also, about ten years ago, spent a lot of energy and money into the growing Multiagent market - and lost most of it. It was an interesting discussion - Richard being the believer, Mike the sceptic, and a lot of young people betting a few years worth of life on the ideas presented by the first one...

SSSW Day 5

Today (which is July 15th) just one talk. The rest of the day - beside the big dinner (oh well, yes, there was a phantastic dinner speech performed by Aldo Gangemi and prepared by Enrico and Asun if I understood it correctly, which was hilariously funny) and the disco - was available for work on the mini projects. But more about the mini projects in the next blog.

The talk was given by University of Manchester's Carol Goble (I like that website. It starts with the sentence "This web page is undergoing a major overhaul, and about time. This picture is 10 years old. the most recent ones are far too depressing to put on a web site." How many professors did you have that would have done this?). She gave a fun and nevertheless insightful talk about the Semantic Web and the Grid, describing the relationship between the two as a very long engagement. The grid is the old, grudgy, hard working groom, the Semantic Web the bride, being aesthetically pleasing and beautiful.

What is getting gridders excited? Flexible and extensible schemata, data fusion and reasoning. Sounds familiar? Yes, these are exactly the main features of Semantic Web technologies! The grid is not about accessing big computers (as most people think in the US, but they are a bit behind on this as well), it is about knowledge communities. But one thing is definitively lacking: scalability, people, scalability. They went to test a few Semantic Web technologies with a little data - 18 million triples. Every tool broke. The scalability lacks, even thought the ideas are great.

John Domingue pointed out, that scalability is not that much of a problem as it seems, because the TBoxes, where the actual reasoning will happen, will always remain relatively small. And the scalability issue with the ABoxes can be solved with classic database technology.

The grid offers real applications, real users, real problems. The Semantic Web offers a lot of solutions and discussions about the best solution - but lack surprisingly often an actual problem. So it is obvious that the two fit together very nicely. At the end, Carole described them as engaged, but not married yet.

At the end she quotes Trotsky: "Revolution is only possible when it becomes inevitable" (well, at least she claims it's Trosky, Google claims its Carole Goble, maybe someone has a source? - Wikiquote doesn't have it yet). The quote is in line with almost all speakers: the Semantic Web is not Revolution, it is Evolution, an extension of the current web.

Thanks for the talk, Carole!

SSSW Last Day

The Summer School on Ontological Engineering and the Semantic Web finished on Saturday, July 16th, and I can't remember having a more intense and packed week in years. I really enjoyed it - the tutorials, the invited talks, the workshops, the social events, the mini project - all of it was awesome. It's a pity that it's all over now.

Today, besides the farewells and thank yous and the party in Madrid with maybe half of the people, also saw the presentation of the mini projects. The mini projects where somewhat similar to the The Semantic Web In One Day we had last year - but without a real implementation. Groups of four or five people had to create a Semantic Web solution in only six hours (well, at least conceptually).

The results were interesting. All of them were well done and highlighted some promising use cases for the Semantic Web, where data integration will play an important role: going out in the evening, travelling, dating. I'd rather not consider too deeply if computer scientists are rather attacking an own itch here ;) I really enjoyed the Peer2Peer theater, where messages wandered through the whole class room in order to visualize the system. This was fun.

Our own mini project modelled the Summer School and the projects itself, capturing knowledge about the buildup of the groups and classifying them. We had to use not only quite complex OWL constructs, but also SWRL-rules - and we still had problems expressing a quite simple set of rules. Right now we are trying to write these experiences down in a paper, I will inform you here as soon as it is ready. Our legendary eternal struggle at the boundaries of sanity and Semantic Web technologies seemed to be impressive enough to have earned us a cool price. A clock.

Thanks to all organizers, tutors and invited speakers of the Summer School, thanks to all the students as well, for making it such a great week. Loved it, really. I hope to stay in touch with all of you and see you at some conference pretty soon!

SWAT4HCLS trip report

This week saw the 12th SWAT4HCLS event in Edinburgh, Scotland. It started with a day of tutorials and workshops on Monday, December 10th, on topics such as SPARQL, querying, ontology matching, and using Wikibase and Wikidata.

Conference presentations went on for two days, Tuesday and Wednesday. This included four keynotes, including mine on Wikidata, and how to move beyond Wikidata (presenting the ideas from my Abstract Wikipedia papers). The other three keynotes (as well as a number of the paper presentation) were all centered on the FAIR concept which I already saw being so prominent at the eScience conference earlier this year. FAIR as in Findable, Accessible, Interoperable, and Reusable publication of data. I am very happy to see these ideas spread out so prominently!

Birgitta König-Ries talked about how to use semantic technologies to manage FAIR data. Dov Greenbaum talked about how licenses interplay with data and what it means for FAIR data - personally, my personal favorite of the keynotes, because of my morbid fascination regarding licenses and intellectual property rights pertaining to data and knowledge. He actually confirmed my understanding of the area - that you can’t really use copyright for data, and thus the application of CC-BY or similar licenses to data would stand on shaky grounds in a court. The last keynote was by Helen Parkinson, who gave a great talk on the issues that come up when building vocabularies, including issues around over-ontologizing (and the siren call of just keeping on modeling) and others. She put the issues in parallel to the travels of Odysseus, which was delightful.

The conference talks and posters were really on spot on the topic of the conference: using semantic web technologies in the life sciences, health care, and related fields. It was a very satisfying experience to see so many applications of the technologies that Semantic Web researchers and developers have been creating over the years. My personal favorite was MetaStanza, web components that visualize SPARQL results in many different ways (a much needed update to SPARK, that Andreas Harth and I had developed almost a decade ago).

On Thursday, the conference closed with a Hackathon day, which I couldn’t attend unfortunately.

Thanks to the organizers for the event, and thanks again for the invitation to beautiful Edinburgh!

SWSA panel

Thursday, October 7, 2021, saw a panel of three founding members of the Semantic Web research community, who each have been my teachers and mentors over the years: Rudi Studer, Natasha Noy, and Jim Hendler. I loved watching the panel and enjoyed it thoroughly, also because it was just great to see all of them again.

There were many interesting insights and thoughts in this panel, too many to write them all down, but I want to mention a few.

It was interesting how much all panelists talked about creating the Semantic Web community, and how much of an intentional effort that was. Deciding that it needs a conference, a journal, an organization, setting those up, and their interactions. Seeing and fostering a sustainable research community grown out of an idea is a formidable and amazing effort. They all mentioned positively the diversity in the community, and that it was a conscious effort to work towards that. Rudi mentioned that the future challenge will be with ensuring that computer science students actually have Semantic Web technologies integrated into their standard curriculum.

They named a number of the successes that were influenced by the Semantic Web research work, such as Schema.org, the heavy use of SPARQL in supercomputing (I had no idea!), Wikidata (thanks for the shout out, Rudi!), and the development of scalable graph databases. Natasha raised the advantage of having common identifiers throughout an organization, i.e. that everyone refers to California the same way. They also named areas that remained elusive and that they expect to see progress in the coming years, Rudi in particular mentioned Agents and Common Sense, which was echoed by the other participants, and Jim mentioned Personal Knowledge Graphs. Jim mentioned he was surprised by the growing importance of unstructured data. Jim is also hoping for something akin to “procedural attachments” - you see some new data coming in, you perform this action (I would like to think that a little Wikifunctions goes a long way).

We need both, open knowledge graphs and closed knowledge graphs (think of your personal ones, but also the ones by companies).

The most important contribution so far and also well into the future was the idea of decentralization of semantics. To allow different stakeholders to work asynchronously and separately on parts of the semantics and yet share data. This also includes the decentralization of knowledge graphs, but also in the future we will encounter a world where semantics are increasingly brought together and yet decentralized.

One interesting anecdote was shared by Natasha. She was talking about a keynote by Guha (one of the few researchers who were namechecked in the panel, along with Tim Berners-Lee) at ISWC in Sydney 2013. How Guha was saying how simple the technology needs to be, and how there were many in the audience who were aghast and shocked by the talk. Now, eight years later and given her experience building Dataset Search, she appreciates the insights. If they have a discussion about a new property for longer than five minutes, they drop it. It’s too complicated, and people will use it wrong so often that the data cleanup will become expensive.

All of them shared the advice for researchers in their early career stage to work on topics that truly inspire them, on problems that are real and that they and others care about, and that if they do so, the results have the best chance to have impact. Think about problems you can explain to people not in your field, about “how can we use triples to save the world” - and not just about “hey, look, that problem that we solved with these other technologies previously, now we can also solve it with Semantic Web technologies”. This doesn’t really help anyone. Solve new problems. Solve real problems. And do what you are truly passionate about.

I enjoyed the panel, and can recommend everyone in the Semantic Web research area or any related, nearby research, to check it out. Thanks to the organizers for this talk (which is the first session in a series of talks that will continue with Ora Lassila early December).

Sacre Coeur

Ich teste nur flickr aus. Angeblich kann flickr direkt auf meinen Blog posten. Und das Bild ist wirklich schön. Aber nicht von mir.

Update: Bild ist nunmehr gesperrt. Es handelte sich um dieses Bild der Kirche Sacre Ceour in Paris, doch es scheint nun auch von flickr entfernt worden zu sein

Sagrada Familia

Ich bin zwar schon zurück aus Barcelona, aber so zwei, drei Nachwehen werde ich dazu noch bloggen. Heute: die Sagrada Familia, die Kathedrale der Heiligen Familie zu Barcelona (noch im Bau). Man kommt hin, und muss schlappe 8 Euro hinblättern für den Eintritt. Erscheint viel, ist es auch.

Aber wie berechnet man den Eintritt für etwas, das wirklich einzigartig ist? Man sieht vor allem eine Baustelle, umgeben von den gewaltigen bestehenden Türmen. Der Aufzug nach oben kostet nochmal 2 Euro, und der Treppenaufgang ist versteckt und finster und dunkel - und sehr lohnenswert. Der Blick über Barcelona, den man von da oben genißen kann, ist nur das Sahnestück, das eigentlich unglaubliche ist die Kathedrale selbst. Höher und höher, Scharten, Fenster, Durchblicke überall, immer wieder fällt der Blick durch ein Fenster, genau auf ein golden Geschriebens Wort, auf eine Engelsfigur, auf eines der unzähligen Elemente der Kathedrale.

Wie gewaltige Mammutbäume schmiegen sich die Säulen an eines der vier Portale, alles scheint gen Himmel zu fließen, überall Zitate aus Natur und Geschichte. Das Museum öffnet einem die Augen für zahlreiche Details, zeigt die Tricks für die fließende Wirkung, entschlüsselt manches Detail aus der Natur, und ich blieb staunend zurück mit der Frage, was Gaudi heute mit einem CAD-Programm anstellen würde, ob er genialer, ob er konservativer wäre...

Teuer, aber sehenswert. Und zudem ein schönes Glockenspiel. Und sehr, sehr hoch...

Sam Altman and the veil of ignorance

(This is not about Altman having been removed as CEO of OpenAI)

During the APEC forum on Thursday, Sam Altman has been cited to having said the following thing: "Four times now in the history of OpenAI—the most recent time was just in the last couple of weeks—I’ve gotten to be in the room when we push the veil of ignorance back and the frontier of discovery forward. And getting to do that is like the professional honor of a lifetime."

He meant that as an uplifting quote to describe how awesome his company and their achievements are.

I find it deeply worrying. Why?

The "veil of ignorance" (also known as the original position) is a thought experiment introduced by John Rawls, one of the leading American moral and political philosophers of the 20th century. The goal is to think about the fairness of a society or a social system without you knowing where in the system you end up: are you on top or at the bottom? What are your skills, your talents? Who are your friends? Do you have disabilities? What is your gender, your family history?

The whole point is to *not* push the veil of ignorance back, otherwise you'll create an unfair system. It is a good tool to think about the coming disruptions by AI technology.

The fact that he's using that specific term but is obviously entirely oblivious to its meaning tells us that there was a path that term took, probably from someone working on ethics to then-CEO Altman, and that someone didn't listen. The meaning was lost, and the beautiful phrase was entirely repurposed.

Given that's coming from the then-CEO of the company that claims and insists on, again and again (without substantial proof) that they are doing all this for the greater benefit of all humanity, that are, despite their name, increasingly closing their results, making public scrutiny increasingly difficult if not impossible - well, I find that worrying. The quote indicates that they have no idea about a basic tool towards evaluating fairness, even worse, have heard about it - but they have not listened or comprehended.

San Francisco and Challenges

Time is running totally crazy on me in the last few weeks. Right now I am in San Francisco -- if you like to suggest a meeting, drop me a line.

The CKC Challenge is going on and well! If you didn't have the time yet, check it out! Everybody is speaking about how to foster communities for shared knowledge building, this challenge is actually doing it, and we hope to get some good numbers and figures out of it. An fun -- there is a mystery prize involved! Hope to see as many of you as possible at the CKC 2007 in a few days!

Yet another challenge with prizes is going on at Centiare. Believe it or not, you can actually make money with using a Semantic MediaWiki, wih the Centiare Prize 2007. Read more there.

Saturn the alligator

Today at work I learned about Saturn the alligator. Born to humble origins in 1936 in Mississippi, he moved to Berlin where he became acquainted with Hitler. After the bombing of the Berlin Zoo he wandered through the streets. British troops found him, gave him to the Soviets, where against all odds he survived a number of near death situations - among others he refused to eat for a year - and still lives today, in an enclosure sponsored by Lacoste.

I also went to Wikidata to improve the entry on Saturn. For that I needed to find the right property to express the connection between Saturn, and the Moscow Zoo, where he is held.

The following SPARQL query was helpful: https://w.wiki/7ga

It tells you which properties connect animals with zoos how often - and in the Query Helper UI it should be easy to change either types to figure out good candidates for the property you are looking for.

Schlagzeuger sind ersetzlich

Durch Maschinen. Diese Studie zeigt eine solche Möglichkeit.

Im ernst, wer Percussion mag, wird sicher dieses Video sehr cool finden. Und wer Musik mag auch. Oder Computerzeichentrick. Ich habe gelesen, dass das Programm, welches das Video erzeugt hat, ein beliebiges Midi reinladen konnte. Man musste dann nur noch die Kameraschwenks und Perspektiven bestimmen. Wow.

Weitere solche Videos bei Google. Die Animusic DVD gibt es auch, in deutlich besserer Qualität, zu kaufen.

Schnitt!

Dass dem Chirurgen notfalls Gesundheit vor einem Tattoo geht, ist ja nur verständlich. Dass durch den Schnitt des Chirurgen ab und an Tattoos beschädigt werden, leider unvermeidbar.

Dumm nur, wenn das Tattoo die Worte I like women bildete, und das wo durch den Schnitt verloren geht... (aus der Zeit)

Schon Juni, wie die Zeit vergeht...

Nachdem im Mai nicht nur die Zahl der Hits geradezu explodierte - Danke, liebe Leser, Danke, Danke, Danke! - sondern sich auch vor allem Schwesterchens Galerie mit inzwischen über 50 Bildern ausdehnte, wird es im Juni ebenso weitergehen: noch mehr Bilder von Schwesterchen warten darauf, in die Galerie zu gelangen, die Jahre 2000-2002 (soweit vorhanden) werden in diesem Monat ihren Platz auf Nodix finden. Die Studienarbeit wollte ich bis heute in einer ersten Version fertig haben, verspäte mich aber ein wenig. Auf alle Fälle wird sie im Laufe des Junis ebenfalls hier auftauchen.

Das zugesagte Entstauben von Nodix hat noch nicht stattgefunden: dafür warteten einfach zu viele neue Inhalte, die hier auf die Seite wollten. Ein völlig andersartiger Text als die meisten dieser Seite, an dem ich ebenfalls beteiligt bin, findet sich übrigens auf baumgarf.de, für die Nodix auch ein wenig Werbung macht. Besagter Text ist das herrlich-unsinnige Frank, neben vielen anderen Sachen, die allemal ein Besuch wert sind.

Und endlich noch ein paar Worte zu den DSA4 Tools: der DSA4 Heldenerschaffer und das DSA4 Heldendokument sind nicht mehr - in den nächsten zwei, drei Tagen werden sie beide von dieser Seite entfernt. Weil sie nämlich durch das DSA4 Werkzeug ersetzt werden! Statt vieler kleiner Tools wird es ein großes geben, welches alle diese Aufgaben erfüllt. Dies hängt auch zusammen mit der baldig anstehenden Entscheidung, ob ich das DSA4 Werkzeug als Open Source Projekt aufziehen werde - spätestens seitdem Schwerter & Helden erschienen sind, scheint diese notwendig klar und deutlich zu sein. Aber dazu sicher mehr im Laufe des Monats... es wird ohnehin noch ein wenig dauern, bis ich den Quelltext soweit aufgeräumt habe, dass ich ihn für veröffentlichbar halte - oder wollt ihr lieber jetzt gleich und sofort damit rumspielen, auch wenn man nicht notwendig durchsteigt?

Soweit die Begrüßung! Vergesst nicht, das tolle Wetter zu genießen, und viel Spaß noch auf den Seiten von Nodx! Schließlich gilt es zu feiern, dass die Aktion 10.000 so gigantisch weiterläuft - über 6000 Hits sind bereits geschafft!

Alles Gute,
ein kurzhaariger
Denny Vrandecic

P.S.: vielen Dank für die lobenden Worte, die ich immer liebend gerne lese. Wer sich auch immer dazu hinreißen lässt, sich die Zeit für etwas Feedback zu nehmen, dem werde ich sicherlich dankbar sein.

Schwesterchens Rückkehr

Schwesterchen ist wohlbehalten daheim angekommen. Nach der Katastrophe von letzter Woche wollten die außerirdischen Entführer von Zirkonia-B das Risiko einer Wiederholung nicht eingehen und haben sie freigelassen! Herzlich Willkommen, Schwesterchen, und Knuddelz!!

Über persönliche Glückwünsche zur bestandenen Entführung freut sich, und über die Mitteilung, dass Ihr ihr Comic vermisst habt, freut sie sich sicher ungemein... schreibt Schwesterchen!

Nebenher angemerkt: das DSA4 Werkzeug Version 1.21 ist erschienen. Mit toller neuen Druckfunktion! Genau genommen, drei verschiedenen Ausgabefunktionen für Heldenbriefe...

Semantic MediaWiki 0.6: Timeline support, ask pages, et al.

It has been quite a while since the last release of Semantic MediaWiki, but there was enormous work going into it. Huge thanks to all contributors, especially Markus, who has written the bulk of the new code, reworked much of the existing, and pulled together the contributions from the other coders, and the Simile team for their great Timeline code that we reused. (I lost overview, because the last few weeks have seen some travels and a lot of work, especially ISWC2006 and the final review of the SEKT project I am working on. I will blog on SEKT more as soon as some further steps are done).

So, what's new in the second Beta-release of the Semantic MediaWiki? Besides about 2.7 tons of code fixes, usability and performance improvements, we also have a number of neat new features. I will outline just four of them:

• Timeline support: you know SIMILE's Timeline tool? No? You should. It is like Google Maps for the fourth dimension. Take a look at the Timeline webpage to see some examples. Or at ontoworld's list of upcoming events. Yes, created dynamically out of the wiki data.
• Ask pages: the simple semantic search was too simple, you think? Now we finally have a semantic search we dare not to call simple. Based on the existing Ask Inline Queries, and actually making them also fully functional, the ask pages allow to dynamically query the wiki knowledge base. No more sandbox article editing to get your questions answered. Go for the semantic search, and build your ask queries there. And all retrievable via GET. Yes, you can link to custom made queries from everywhere!
• Service links: now all attributes can automatically link to further resources via the service links displayed in the fact box. Sounds abstract? It's not, it's rather a very powerful tool to weave the web tighter together: service links specify how to connect the attributes data to external services that use that data, for example, how to connect geographic coordinates with Yahoo maps, or ontologies with Swoogle, or movies with IMdb, or books with Amazon, or ... well, you can configure it yourself, so your imagination is the limit.
• Full RDF export: some people don't like pulling the RDF together from many different pages. Well, go and get the whole RDF export here. There is now a maintenance script included which can be used via a cron job (or manually) to create an RDF dump of the whole data inside the wiki. This is really useful for smaller wikis, and external tools can just take that data and try to use it. By the way, if you have an external tool and reuse the data, we would be happy if you tell us. We are really looking forward to more examples of reuse of data from a Semantic MediaWiki installation!

I am looking much forward to December, when I can finally join Markus again with the coding and testing. Thank you so very much for your support, interest, critical and encouraging remarks with regards to Semantic MediaWiki. Grab the code, update your installation, or take the chance and switch your wiki to Semantic MediaWiki.

Just a remark: my preferred way to install both MediaWiki and Semantic MediaWiki is to pull it directly from the SVN instead of taking the releases. It's actually less work and helps you tremendously in keeping up to date.

Semantic MediaWiki 1.0 released

After about two years of development and already with installations all over the world, we are very happy to announce the release of Version 1.0 of Semantic MediaWiki, and thus the first stable version. No alpha, no beta, it's out now, and we think you can use it productively. Markus managed to release it in 2007 (on the last day of the year), and it has moved far beyond what 0.7 was, in stability, features, and performance. The biggest change is a completely new ask syntax, much more powerful since it works much smoother with MediaWiki's other systems like the parser functions, and we keep constantly baffling ourselves about what is possible with the new system.

We have finally reached a point where we can say, OK, let's go for massive user testing. We want big and heavy used installations to test our system. We are fully aware that the full power of the queries can easily kill an installation, but there are many ways to tweak performance and expressivity. We are now highly interested in performance reports, and then moving towards our actual goal, Wikipedia.

A lot has changed. You can find a full list of changes in the release notes. And you can download and install Semantic MediaWiki form SourceForge. Spread the word!

There remains still a lot of things to do. We have plenty of ideas how to make it more useful, and our users and co-developers also seem to have plenty of ideas. It is great fun to see the numbers of contributors to the code increase, and also to see the mailing lists being very lively. Personally, I am very happy to see Semantic MediaWiki flourish as it does, and I am thankful to Markus for starting this year (or rather ending the last) with such a great step.

Semantic MediaWiki Demo

Yeah! Doccheck's Klaus Lassleben is implementing the Semantic MediaWiki, and there's a version of it running for quite some time already, but some bugs had to be killed. Now, go and take a look! It's great.

And the coolest thing is the search. Just start typing the relation, and it gives you an autoexpansion, just like Google Suggest does (well, a tiny bit better :) Sure, the autoexpansion is no scientific breakthrough, but it's a pretty darn cool feature.

The SourceForge project Semediawiki is already up and running, and I sure hope that Mr Lassleben will commit the code any day soon!

Even better, Sudarshan has already started implementing extensions to it - without having the code! That's some dedication. His demo is running here, and shows how the typed links may be hidden from the source text of the wiki, for those users who don't like it. Great.

Now, go and check the demo!

Semantic MediaWiki goes business

... but not with the developers. Harry Chen writes about it, and several places copy the press release about Centiare. Actually, we didn't even know about it, and were a bit surprised to hear that news after our trip to India (which was very exciting, by the way). But that's OK, and actually, it's pretty exciting as well. I wish Centiare all the best! Here is their press release.

They write:

Centiare's founder, Karl Nagel, genuinely feels that the world is on the verge of an enormous breakthrough in MediaWiki applications. He says, "What Microsoft Office has been for the past 15 years, MediaWiki will be for the next fifteen." And Centiare will employ the most robust extension of that software, Semantic MediaWiki.

Wow -- I'd never claim that SMW is the most robust extension of MediaWiki -- there are so many of them, and most of them have a much easier time of being robust! But the view of MediaWiki taking the place of Office -- Intriguing. Although I'd put my bets rather on stuff like Google Docs (former Writely), and add some semantic spice to it. Collaborative knowledge construction will be the next big thing. Really big I mean. Oh, speaking about that, check out this WWW workshop on collaborative knowledge construction. Deadline is February 2nd, 2007.

Semantic MediaWiki officially Beta

Semantic MediaWiki has gone officially Beta. Markus Krötzsch released Version 0.5 yesterday -- download it at Sourceforge and update your installation!

Markus and I are both busy today updating existing installations (and creating new ones -- greetings towards California!). The new version has several new features:

• One can reuse existing Semantic Web vocabulary, like FOAF. This feature is used so strongly, it led to Swoogle actually believing, FOAF was defined at ontoworld!
• The unit code was improved a lot -- one can define linear units now from inside the wiki. Africa has a list of all African countries, and you can see their size neatly listed.
• New datatypes for URLs and Emails.
• Better code (why we dare to call us Beta)

Check out the new features on ontoworld. Thanks for Markus and S for the coding marathon this weekend, that allowed to make this new release! We are fetching bugs now, and planning 0.6, and our first big stress tests, with lots and lots of data...

Semantic MediaWiki: The code is out there

Finally! 500 nice lines of code, including the AJAX-powered search, and that's it, version 0.1 of the SeMediaWiki project! Go to Sourceforge and grab the source! Test it! Tell us about the bugs you found, and start developing your own ideas. Create your own Semantic Wiki right now, today.

Well, yes, sure, there is a hell of a lot left to do. Like a proper triplestore connecting to the Wiki. Or a RDF-serialization. But hey, there's something you can play with.

Semantic Mediawiki 0.3

Yay! Markus "the Sorcerer" Krötzsch finished the new release of Semantic MediaWiki today. The demo website is already running version 0.3 for a while.

I'll let Markus speak:

I am glad to finally announce the official release of Semantic MediaWiki 0.3, available as usual at http://sourceforge.net/projects/semediawiki/. The final 0.3 is largely equivalent to the preview version that is still running on wiki.ontoworld.org -- the latest changes mainly concern localization.

Semantic MediaWiki 0.3 now runs on MediaWiki 1.6.1 that was released just yesterday. Older versions of MediaWiki should also work but upgrading is generally recommended.

The main new features of 0.3 are:

• support for geographical coordinates (new datatype),
• improved user interface: service links for JScript tooltips, CSS layout,
• OWL/RDF export of all annotation data,
• simplified installation process (including special page for setup/upgrade),
• (almost) complete localization; translations available for English and German,
• better MediaWiki integration: namespaces, user/content language, support for MediaWiki 1.6,
• specials for displaying all relations/attributes,
• experimental (OWL/RDF) ontology import feature,
• and, last but not least, we also fixed quite some bugs.

The next steps towards 0.4 will probably be the inclusion of query results into existing pages, date/time support, and individual user settings for displaying certain datatypes. We also will have another look at ways of hiding the annotations from uninitiated users.

Have fun.

Markus

P.S.: I am not available during the weekend. Upgrading existing wikis should work (it's what we do all the time ;), but be aware that there is not going to be much support during the next three days.

Semantic Mediawiki 0.4 - Knowledge Inside!

Until now, Semantic MediaWiki was kind of a nerds project. Yes, you could get a lot of information out in RDF, and actually, I used it as an RDF editor more than once -- but heck, what normal person needs that?

Now, with the freshly implemented feature, the advantages of a Semantic MediaWiki over a normal MediaWiki should become obvious: you can simply ask the wiki for stuff! Wiki, what are the 10 biggest city in the US? Put a list here. Or, wiki, what is the height of the current German chancellor? Put the info here. I have made a writeup on those inline queries on our demo wiki. Go there, read it.

But a lot of other things made it into the 0.4 release. Here's Markus' list:

• Improved output for Special:Relations and Special:Attributes: usage of
• relations and attributes is now counted
• Improved ontology import feature, allowing to import ontologies and to update existing pages with new ontological information
• Experimental suport for date/time datatype
• More datypes with units: mass and time duration
• Support for EXP-notation with numbers, as e.g. 2.345e13. Improved number formating in infobox.
• Configurable infobox: infobox can be hidden if empty, or switched off completely. This also works around a bug with MediaWiki galeries.
• Prototype version of Special:Types, showing all available datatypes with their names in the current language setting.
• "[[:located in::Paris]]" will now be rendered as "located in [[Paris]]"
• More efficient storage: changed database layout, indexes for fast search
• Code cleaned up, new style guidelines
• Bugfixes, a lot of Bugixes

Thanks to everyone who contributed and still contributes to the project! And, connected to this, thanks to the answers to my last blog entry -- I will write more on this tomorrow.

Semantic Scripting

Oh my, I really need to designate some time to this blog. But let's not ranting about time - no one of us has time - let's directly dive into my paper for the Workshop on Scripting for the Semantic Web on the 2nd ESWC in Heraklion next week. Here is the abstract.

Python reached out to a wide and diverse audience in the last few years. During its evolution it combined a number of different paradigms under its hood: imperative, object-oriented, functional, listoriented, even aspect-oriented programming paradigms are allowed, but still remain true to the Python way of programming, thus retaining simplicity, readability and fun. OWL is a knowledge representation language for the definition of ontologies, standardised by the W3C. It reaps upon the power of Description Logics and allows both the definition of concepts and their interrelations as well as the description of instances. Being created as part of the notoriously known Semantic Web language stack, its dynamics and openness lends naturally to the ever evolving Python language. We will sketch the idea of an integration of OWL and Python, but not by simply suggesting an OWL library, but rather by introducing and motivating the benefits a really deep integration offers, how it can change programming, and make it even more fun.

You can read the full paper on Deep Integration of Scripting Languages and Semantic Web Technologies. Have fun! If you can manage it, pass by the workshop and give me your comments, rants, and fresh ideas - as well as the spontaneous promise to help me design and implement this idea! I am very excited about the workshop and looking forward to it. See you there!

Semantic Web Gender Issue

Well, at least they went quite a way. With Google Base one can create new types of entities, entities themselves, and search for them. I am not too sure about the User Interface yet, but it's surely one of the best actually running onbig amounts of data. Nice query refinement, really.

But heck, there's one thing that scares me off. I was looking today for all the people interested in the Semantic Web, and there are already some in. And you can filter them by gender. I was just gently surprised about the choices I was offered when I wanted to filter them by gender...

Hier fehlt noch ein Bild.

Oh come on, Google. I know there are not that many girls in computer science, but really, it's not that bad!

Semantic Web Summer School 2006

The Summer School for the Semantic Web and Ontological Engineering is an annual event that brings together PhD students from all over the world and some of the brightest heads in the Semantic Web, to teach, to socialize, to learn, and to have fun. This year's invited speakers are Jim Hendler himself, and Enrico Motta, Stephan Baumann, Guus Schreiber, and the tutors are John Domingue, Asun Gomez-Perez, Jerome Euzenat, Sean Bechhofer, Fabio Ciravegna, Aldo Gangemi. You will learn a lot. You will have lots of fun. The place is really beautiful, the girls, well at least last year, were really beautiful, the stuff we learned was interesting, and inspired quite some cooperation further on. And it's really great for getting to know a lot of people: at the next conference you're guaranteed to meet someone again, and thus it is also a perfect possibility ot get into the community.

The deadline is May 1st, so be sure to go over to the SSSW2006 website and sign up.

If this didn't convince you, take a look at my series of posts about last year's summer school.

Semantic Web and Web 2.0

I usually don't just point to other blog entries (thus being a bad blogger regarding netiquette), but this time Benjamin Nowack nailed it in his post on the Semantic Web and Web 2.0. I read the iX article (a popular German computer technology magazine), and I lost quite some respect for the magazine as there were so many unfounded claims, off-the-hand remarks, and so much bad attitude in the article (and in further articles scuttered around the issue) towards the Semantic Web that I thought the publisher was personally set on a crusade. I could go through the article and write a commentory on it, and list the errors, but honestly, I don't see the point. At least it made me appreciate peer review and scientific method a lot more. The implementation of peer review is flawed as well, but I realize it could be so much worse (and it could be better as well - maybe PLoS is a better implementation of peer review).

So, go to Benji's post and convince yourself: there is no "vs" in Semantic Web and Web 2.0.

Semantic Web patent

Tim Finin and Jim Hendler are asking about the earliest usage of the term Semantic Web. Tim Berners-Lee (who else?) spoke about the need of semantics in the web at the WWW 1994 plenary talk in Geneva, though the term Semantic Web does not appear there directly. Whatever. What rather surprised me, though, is, when surfing a bit for the term, I discovered that Amit Sheth, host of this year's ISWC, filed the patent on it, back in 2000: System and method for creating a Semantic Web. My guess would be, that is the oldest patent of it.

Semantic Wikipedia

Marrying Wikipedia and the Semantic Web in Six Easy Steps - that was the title of the WikiMania 2005 presentation we gave about a month ago. On the Meta-Wikipedia we - especially Markus Krötzsch - were quite active on the Semantic MediaWiki project, changing and expanding our plans. DocCheck is working right now on a basic implementation of the ideas - they have lots of Wiki-Experience already, with Flexicon, a MediaWiki-based medical lexicon. We surely hope the prototype will be up and running soon!

Wow, the project seems perceived pretty well.

Tim Finin, Professor in Maryland: "I think this is an exciting project with a lot of potential. Wikipedia, for example, is marvelously successful and has made us all smarter. I’d like my software agents to have a Wikipedia of their own, one they can use to get the knowledge they need and to which they can (eventually) contribute." - Wikipedia meets the Semantic Web, Ebiquity blog at UMBC

Mike Linksvayer, CTO of Creative Commons: "The Semantic MediaWiki proposal looks really promising. Anyone who knows how to edit Wikipedia articles should find the syntax simple and usable. All that fantastic data, unlocked. (I’ve been meaning to write on post on why explicit metadata is democratic.) Wikipedia database dump downloads will skyrocket." - Annotating Wikipedia, Mike Linksvayers Blog

Danny Ayers, one of the developers of Atom and Author of Atom and RSS Programming: "The plan looks very well thought out and quite a pile of related information has been gathered. I expect most folks that have looked at doing an RDF-backed Wiki would come to the same conclusion I did (cf. stiki) - it’s easy to do, but difficult to do well. But this effort looks like it should be the one." - Wikipedia Bits, Danny Ayers, Raw Blog

Lambert Heller of the University of Münster wrote a German blog entry on the netbib weblog, predicting world domination. Rita Nieland has a Dutch entry on her blog, calling us heroes - if we succeed. And on Blog posible Alejandro Gonzalo Bravo García has written a great Spanish entry, saying it all: the web is moving, and at great speed!

So, the idea seems catching like a cold in rainy weather, we really hope the implementation will soon be there. If you're interested in contributing - either ideas or implementation - join our effort! Write us!

Semantic Wikipedia presentations

Last week on the Semantics 2006 Markus and I gave talks on the Semantic MediaWiki. I was happy to be invited to give one of the keynotes at the event. A lot of people were nice enough to come to me later to tell me how much they liked the talk. And I got a lot of requests for the slides. I decided to upload them, but wanted to clean them a bit. I am pretty sure that the slides are not self-sufficient -- they are tailored to my style of presentations a lot. But I added some comments to the slides, so maybe this will help you understand what I tried to say if you have not been in Vienna. Find the slides of the Semantics 2006 keynote on Semantic Wikipedia here. Careful, 25 MB.

But a few weeks ago I was at the KMi Podium for an invited talk there. The good thing is, they don't have just the slides, they also have a video of the talk, so this will help much more in understanding the slides. The talk at KMi has been a bit more technical and a lot shorter (different audiences, different talks). Have fun!

Shazam!

Shazam! was fun. And had more heart than many other superhero stories. I liked that, for the first time, a DC universe movie felt like it's organically part of that universe - with all the backpacks with Batman and Superman logos and stuff. That was really neat.

Since I saw him in the first trailer I was looking forward to see Steve Carell playing the villain. Turns out it was Mark Strong, not Steve Carell. Ah well.

I am not sure the film knew exactly at whom it was marketed. The theater was full with kids, and given the trailers it was clear that the intention was to get as many families into it as possible. But the horror sequences, the graphic violence, the expletives, and the strip club scenes were not exactly for that audience. PG-13 is an appropriate rating.

It was a joy to watch the protagonist and his buddy explore and discover his powers. Colorful, lively, fun. Easily the best scenes of the movie.

The foster family drama gave the movie it's heart, but the movie seemed a bit overwhelmed by it. I wish that part was executed a bit better. But then again, it's a superhero movie, and given that it was far better than many of the other movies of its genre. But as far as High School and family drama superheroes go, it doesn't get anywhere near Spiderman: Homecoming.

Mid credit scenes. A tradition that Marvel started and that DC keeps copying - but unlike Marvel DC hasn't really paid up to the teasers in their scenes. And regarding cameos - also something where DC could learn so much from Marvel. Also, what's up with being afraid of naming their heroes? Be it in Man of Steel with Superman or here with Billy, the hero doesn't figure out his name (until the next movie comes along and everybody refers to him as Superman as if it was obvious all the time).

All in all, an enjoyable movie while waiting for Avengers: Endgame, and hopefully a sign that DC is finally getting on the right path.

She likes music, but only when the music is loud

Original in German by Herbert Grönemeyer, 1983.

She sits on her windsill all day
Her legs dangling to the music
The noise from her room
drives all the neighbours mad
She is content
smiles merrily

She doesn't know
that snow
falls
without a sound
to the ground

Doesn't notice
the knocking
on the wall

She likes music
but only
when the music is loud
When it hits her stomach
with the sound

She likes music
but only
when the music is loud
When her feet feel
the shaking ground

She then forgets
that she is deaf

The man of her dreams
must play the bass
the tickling in her stomach
drives her crazy

Her mouth seems
to scream
with happiness
silently
her gaze removed
from this world

Her hands don't know
with whom to talk
No one's there
to speak to her

She likes music
but only
when the music is loud
When it hits her stomach
with the sound

She likes music
but only
when the music is loud
When her feet feel
the shaking ground

Site went down

The site went down, again. First time was in July, when Apache had issues, this time it's due to MySQL acting up and frying the database. I found a snapshot from July 2019, and am trying to recreate the entries from in between (thanks, Wayback Machine!)

Until then, at least the site is back up, even though they might be some losses in the content.

P.S.: it should all be back up. If something is missing, please email me.

Sky Captain and the World of Tomorrow

aus der Reihe Filme in 50 Worten

Ein Film, der so mordsmäßig dick aufträgt und sich derart frech bei allen Klassikern bedient, dass es richtig cool wird. Die Schauspieler spielen ihre Rollen perfekt - ob Gwyneth Paltrow, ob Jude Law, und insbesondere Angelina Jolie.
Man merkt gar nicht, dass der ganze Film - außer den Schauspielern (und selbst von ihnen einer, der schon eine Weile lange nicht mehr lebt - Lawrence Olivier) - aus dem Computer stammt. Der Sprung von Final Fantasy zu Sky Captain ist unglaublich.
Die Story ist banal, und dennoch in ihrer naiven Übertriebenheit extrem spaßig, die Figuren sind klischeehaft wie seit langem nicht und die Sprüche dermaßen knackig, dass es eine Freude ist.

Reingehen!

Auch Schwesterchen hat einen Blog, inzwischen! Hier ihr Kommentar zu Sky Captain and the World of Tomorrow.

Sleeping Lady with a Black Vase

In 2009, a Hungarian art historian was watching the movie Stuart Little with his 3 year old daughter. And he's like "funny, that painting that's used in the set looks like that 1928 black and white photograph I have seen, of a piece of art which has been lost". So he sends a few emails...

Turns out, it *is* the actual artwork by Róbert Berény (1887-1953) which was last seen in public in 1928, and somehow made it to Sony, where it was used in a number of soap opera episodes and in Stuart Little.

Social Web and Knowledge Management

Obviously, the social web is coming. And it's also coming to this year's WWW conference in Beijing!

I find this topic very interesting. The SWKM picks up the theme of last year's very successful CKC2007 workshop, also at the WWW, where we aimed at allowing the collaborative knowledge construction. The SWKM is a bit broader, since it is not just about knowledge construction, but about the whole topic of knowledge management, and how the web changes everything.

If you are interested in the social web, or the semantic web, or specifically about the intersection of these two, and how it can be applied for knowledge management within or without an organisation, you will like the SWKM workshop at the WWW2008. You can submit papers until January 21st, 2008. All information can be found at the Social Web and Knowledge management workshop website.

Social tagging und Co

Cool. Ich sei im Januar Inspiration für diesen Blogeintrag zu Social Tagging mit del.icio.us, flickr und ähnlichem gewesen. Scheint, als hätte ich meine Arbeit nicht soo schlecht gemacht... (und dabei war ich nach genau dieser ersten Sitzung davon überzeugt, dass ich grottig gewesen sei. Aber das bin ich ja von eigener Arbeit zunächst immer...)

Something Positive in Deutsch wieder online

2005 und 2006 übersetzten Ralf Baumgartner und ich die ersten paar Something Positive comics von R. K. Milholland ins Deutsche. Die 80 Comics, die wir damals übersetzt haben, sind hiermit wieder online. Wir haben noch vier weitere Comics übersetzt, die in den nächsten Tagen auch nach und nach online kommen werden.

Viel Spass! Oh, und die Comics sind für Erwachsene.

Sommerpause

Die Pause verlängert sich. Heute geht es nach Bielefeld, Sonntag zurück, und am Montag geht es für eine Woche nach Kroatien. Sorry!

Sommerpause 2003

So, jetzt gibt es zunächst mal Sommerpause mit den nutkidz, Nodix selbst wird sich vorerst auch kaum verändern. In den nächsten Wochen wird meine Diplomarbeit hier vorgestellt, und die Ergebnisse online gestellt, aber für mehr ist zur Zeit schlicht keine Zeit vorhanden. Sorry, hätte Euch früher informieren sollen!

Aber keine Angst, wir kommen wieder!

Spring cleaning

Going through my old online presence and cleaning it up is really a trip down memory lane. I am also happy that most - although not all - of the old demos still work. This is going to be fun to release it all again.

Today I discovered that we had four more German translations of Something Positive that we never published. So that's another thing that I am going to publish soon, yay!
