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!

Standpunkt (nicht meiner!)

"We could really speed up the whole process of drug improvement if we did not have all the rules on human experimentation. If companies were allowed to use clinical trials in Third World countries, paying a lot of poor people to take risks that you wouldn't take in a developed country, we could speed up technology quickly. But because of the Holocaust --"

Stanford seminar on Knowledge Graphs

My friend Vinay Chaudhri is organising a seminar on Knowledge Graphs with Naren Chittar and Michael Genesereth this semester at Stanford.

I have the honour to present in it as the opening guest lecturer, introducing what Knowledge Graphs are and what are good for.

Due to the current COVID situation, the seminar was turned virtual, and opened to everyone to attend to.

Other speakers during the semester include Juan Sequeda, Marie-Laure Mugnier, Héctor Pérez Urbina, Michael Uschold, Jure Leskovec, Luna Dong, Mark Musen, and many others.

Star Trek's 32nd century

I like Star Trek for the cool technology, which has inspired plenty of people to work eg on "the Star Trek computer". I love Star Trek for the utopian society of plenty they sketch in the 23rd and 24th century.

I claim it is because of the laziness of the writing: they don't keep that utopia up.

When I heard about Discovery going to the 32nd century, I was excited about the wonders they would dream up. The new technology. The society. The culture. The breakthroughs.

With regards to that, it was a massive let down. Extremely disappointing.

Stars in our eyes

I grew up in a suburban, almost rural area in southern Germany, and I remember the hundreds, if not thousands of stars I could see at night. In the summers, that I spent on an island in Croatia, it was even more marvelous, and the dark night sky was breathtaking.

As I grew up, the stars dimmed, and I saw fewer and fewer of those, until only the brightest stars were visible. It was blindingly obvious that air and light pollution have swallowed that every-night miracle and confined it to my memory only.

Until in my late twenties I finally accepted and got glasses. Now the stars are back, as beautiful and brilliant as they have ever been.

Start the website again

This is no blog anymore. I haven't had entries for years, and even before then sporadically. This is a wiki, but somehow it is not that either. Currently you cannot make comments. Updating the software is a pain in the ass. But I like to have a site where I can publish again. Switch to another CMS? Maybe one day. But I like Semantic MediaWiki. So what will I do? I do not know. But I know I will slowly refresh this page again. Somehow.

A new part of my life is starting soon. And I want to have a platform to talk about it. And as much as I like Facebook or Google+, I like to have some form of control over this platform. Facebook and Google+ -- maybe they won't disappear in a year. But what about ten? Twenty? Fifty years? I'll still be around (I hope), but they might not...

Let's see what will happen here. For now, I republished the retelling of a day as a story I first published on Google+ (My day in Jerusalem) and a poem that feels eerily relevant whenever I think about it (Wenn ich wollte)

Starting Abstract Wikipedia

I am very happy about the Board of the Wikimedia Foundation having approved the proposal for the multilingual Wikipedia aka Abstract Wikipedia aka Wikilambda aka we'll need to find a name for it.

In order to make that project a reality, I will as of next week join the Foundation. We will be starting with a small, exploratory team, which will allow us to have plenty of time to continue to socialize and discuss and refine the idea. Being able to work on this full time and with a team should allow us to make significant progress. I am very excited about that.

I am sad to leave Google. It was a great time, and I learned a lot about running *large* projects, and I met so many brilliant people, and I ... seriously, it was a great six and a half years, and I will very much miss it.

There is so much more I want to write but right now I am just super happy and super excited. Thanks everyone!

Statistiken

Grummel, pah, der letzte Eintrag war kein sogenanntes fishing for compliments, deswegen habe ich ihn auch wieder rausgemacht. Ich weiß, das kann ich jetzt gerne drei Mal behaupten, glauben wird es mir eh keiner...

Wie ihr wahrscheinlich wisst, bin ich furchtbar zahlenvernarrt. Insbesondere Statistiken mag ich sehr gerne, und stelle sie auch gerne selber auf. Und da gerade gestern wieder ein Monatsanfang war, und ich Euch ja schon letzten Monat mit Hochrechnung bezüglich des Projekts 100.000 langweilte, hier meine aktuellen Zahlen: zum 1. März hattet Ihr tatsächlich 29.073 Hits geschafft! Wow, herzlichen Glückwunsch, das sind 4.860 Hits alleine im Februar - Wahnsinn, besonders im Vergleich zu den 3.776 Hits im Januar.

Zudem, zum 1. März waren folgende Zahlen erwartet (nach den verschiedenen Hochrechnung, wie ich sie letzten Monat ja vorgestellt habe): Lineare Hochrechnung kam auf 32.980 (die einzige Hochrechnung, die wir nicht erreicht haben), die Hochrechnungen, die von linearem Wachstum ausgingen, besagten 25.583 bzw. 26.331, die von quadratischen Wachstum ausgehenden gar nur 24.500. Die beste Hochrechnung ist und bleibt die aus dem Bauch heraus: sie besagt zum 1. März eine Besucherzahl von 27.000 - damit lag sie deutlich am nähesten bei der tatsächlichen Zahl.

Trotz der ganzen Zahlen darf ich nicht vergessen, wem ich das alles verdanke: Euch! Ihr seid Klasse! Ich hoffe sehr, die Website gefällt Euch. Wenn nicht, schreibt! Wenn doch, schreibt auch! :) Einen schönen März, allemal.

Status

Viel zu wenig Zeit... sorry, für die Inaktivität auf Nodix selbst. Ich bin gerade heftig daran, meine Hausarbeit über den ontologischen Status Neuronaler Netze zu schreiben - hochinteressant! Wer mir dazu Fragen beantworten kann, soll sich bitte mal bei mir melden, ich knacke da noch an einigen Nüssen, zu denen ich keine Literatur finde...
Sobald sie fertig ist, wird auch diese Arbeit hier auftauchen. Auch die noch übriggebliebenen Nodix-Rubriken werden demnächst weichen - Nodix wird zu einer reinen Sammlung von Essays, Aufsätzen und sonstigen Texten aus meiner Feder (na ja, eher Tastatur). Die sonstigen Themen werden je mehr als erfolgreich von den restlichen Seiten der Nodix-Gruppe abgedeckt.

Hier nur zu den Webcomics:
nutkidz erscheinen wieder halbwegs regelmäßig (freu)! Ohne zuviel versprechen zu wollen, zielen wir wieder auf eine wöchentliche Erscheinungsweise, wahrscheinlich Ende der Woche jeweils. Und es geht rund: aus den Logs entnehme ich, dass alleine die nutkidz inzwsichen etwa 300-400 regelmäßige Leser anziehen! Hurra! Auch gibt es für die nutkidz endlich ein Gästebuch! Schwesterchen und ich würden uns sehr über Eure Einräge freuen!
Something*Positive auf Deutsch ist hervorragend angelaufen, und dank der Hilfe von Buddy konnten wir auch - trotz meiner mehrtätigen Abwesenheit - weiterhin täglich einen neuen Comic hochfahren! Klasse, und hier nochmal Dank, auch und gerade für die Übersetzungen.

Hier fehlt noch ein Bild.

Und, noch zum Abschluss: hier die Besuche der letzten Woche. Als ich die Statistik das erste Mal sah, überlegte ich mir, ob mir mein Provider nicht vielleicht irgendetwas mitteilen möchte... :)

Studienarbeit RC1

Geschafft! Der Release Candidate meiner Studienarbeit Sichtpunkte in der Software-Architektur ist fertig, und per diesem Link als PDF erhältlich.

Sollte irgendjemand die Zeit finden, sich diese anzuschauen, und Kommentare loswerden zu wollen: nur zu! Bis Mitte nächste Woche nehme ich Kommentare an, danach wird das Ding gedruckt, gebunden und abgegeben.

Nun denn, jetzt heißt es, daran weiterarbeiten. Ich weiß schon, wo ich noch was verbessern möchte.

Studienarbeit fertig!

So, die Studienarbeit ist fertig. Wer mir einen großen Gefallen tun möchte, kann sie sich ja runterladen und nochmal nach Fehlern suchen. Aber nur bis heute mittag etwa, dann geht sie in die Produktion.

Hiermit ist auch auf den Informatikseiten von Nodix die Sektion Sichtpunkte in der Software-Architektur eröffnet. Noch findet sich nur der Download dort, aber demnächst soll der ganze Text der Studienarbeit über zugänglich gemacht werden.

Danke für eure Geduld, und vielen Dank für die Korrekturanmerkungen zur letzten Version! Übrigens, der größte Fehler ist uns allen nicht aufgefallen, erst mein Betreuer hat mich in einer e-Mail heute darauf aufmerksam gemacht: das Wort Sichtpunkt ist gar kein Wort der deutschen Sprache! Ha, da staunt ihr. Ich war auch verwundert, glaubt mir...

Summer School for the Semantic Web, Day 0

Arrived in Cercedilla today, at the Semantic Web Summer School. I really was looking forward to these days, and now, flipping through the detailed programme I am even more excited. This will be a very intense week, I guess, where we learn a lot and have loads of fun.

I was surprised by the sheer number of students being here: 56 or 57 students have come to the summer school, from all over the world - met someone from Australia, from Pittsburgh, and many Europeans. Happily, I also met quite a number of people I already knew, and thus I know it will be a pleasurable week. But let's just do the math for a second: we have more than 50 accepted students at this summer school. There are at least three other summer schools with related fields, like the one in Ljubljana the week before, there's one in Edinburgh, and the ESSLLI. So, that's about 200 students. Even if we claim that every single PhD student is going to a summer school - which I don't think - that would mean we get 200 theses every year! (Probably this number will be only reached in three years or so)

So, just looking at the sheer amount of people working on it - what's the expected impact?

Interesting times lie ahead.

Supporting disaster relief with semantics

Soenke Ziesche, who has worked on humanitarian projects for the United Nations for the last six years, wrote an article for xml.com on the use of semantic wikis in disaster relief operations. That is a great scenario I never thought about, and basically one of these scenarios I think of when I say in my talks: "I'll be surprised if we don't get surprised by how this will be used." Probably I would even go to state the following: if nothing unexpected happens with it, the technology was too specific.

Just the thought that semantic technology in general, and maybe even Semantic MediaWiki in particular, could relief the effects of a natural disaster, or maybe even safe a life, this thought is so incredible exciting and rewarding. Thank you so much Soenke!

Taking Lives

Ach, wie peinlich. Im gestrigen Eintrag waren gleich zwei (nunmehr korrigierte) Fehler. Die Hauptdarstellerin ist nich Judd (eigentlich Jude) Law sondern Ashley Judd, und der bessere Film des Genres heißt nicht Taking Lifes sondern Taking Lives. Danke an Kai und Ralf für die Hinweise! Als kleine Gegenleistung gibt es genau diesen Film als weitere Folge aus der Reihe Filme in 50 Worten

Wollten wir nicht schon immer mal jemand anderes sein? Wo wir uns aber nicht trauen, lebt der Schurke dieses Films diesen Traum. Dummerweise heißt die Konsequenz, dass er den anderen Personen zuvor das Leben nehmen muss, um dasselbe zu Leben. Nicht überraschend folgt daraus eine Mordserie, und gleich nach dem ersten entdeckten Mord ruft der kanadische Polizeichef das FBI um Hilfe, und das schickt Lara Croft, Angelina Jolie, die mit Vorliebe in Gräbern liegt und Leichen zum Frühstück betrachtet.
Die kanadische Polizei bestätigt mit ihren Fähigkeiten im Folgenden mehrfach die Entscheidung des Polizeichefs mit ihrer erschütternden Inkompetenz bei Hausbewachung und Personenschutz. Ein klein wenig wird sich Freud freuen, weil wir herausfinden, dass die Mutter des Täters an allem Schuld trägt und...

Ach, man kann gar nicht viel mehr erzählen, ohne die Pointe zu verraten (die man aber ohnehin die ganze Zeit erahnt). Ethan Hawke und Angelina Jolie biten ein glaubwürdiges Team, Kiefer Sutherland hat hingegen keine exponierte Rolle, egal, wie groß sein Name auf den Plakaten steht. Die Storyautoren haben sich einiges einfallen lassen, aber eigentlich das Beste am Film sind die ersten paar Minuten. Alles sonstige läuft mit einer gewissen Konsequenz ab, die kaum Raum für echte Überraschungen lässt.
Kurz: solider Film für alle, die das Genre mögen. Für alle anderen: warum Taking Lives, wenn doch Big Fish läuft?

Taking a self-driving car

Ten years ago, my daughter was just born and I just joined Google, who were working on self-driving cars. And I was always hoping that my daughter would not have to need to learn how to drive a car (but that if she wanted, she may). In the last ten years I lost confidence in that hope.

Yesterday, thanks to my wife organizing it, we took our first ride with a self-driving car, driving about ten minutes through San Francisco. And I guess a world-wide roll out will take time, maybe a lot of time, but what can I say: it drove very well.

Talk in Korea

If you're around this Tuesday, February 13th, in Seoul, come by the Semantic Web 2.0 conference. I had the honour to be invited to give a talk on the Semantic Wikipedia (where a lot is happening right now, I will blog about this when I come back from Korea, and when the stuff gets fixed).

Looking forward to see you there!

Team America

Ab morgen bin ich im Neandertal, und wer weiß schon, wie da die Internetverbindung ist. Also muss ich noch schnell einen Tipp für alle Kinogänger loswerden, zu einem Film, den niemand verpassen sollte - Team America!

Ein Film mit Alec Baldwin, Liv Tyler, Matt Damon, Sean Penn, Michael Moore, Samuel L. Jackson, Kim Il-Yong, George Clooney und vielen anderen - und das waren nur Nebenrollen! Das South Park Team macht einen bösen, bösen Film, mit schwärzesten Humor und einem Hauch an Kritik an gewissen amerikanischen imperialistischen Tendenzen.

Heißer Sex, unglaubliche Action-Sequenzen, wie sie noch nie zuvor mit dieser Technik (Marionetten) ausgeführt wurden, an den großen Schauplätzen dieser Welt (Nordkorea, Kairo, Paris, Mount Rushmore, Washington) - was will man mehr? Für ausgesprochene Cineasten sind zudem äußerst subtile Zitate auf die großen Kinofilme der letzten Jahrzehnte eingebaut (Star Wars oder Matrix).

Im Kino ab dem 30. Dezember.

Auch auf baumgarf wird ein Review von Team America geboten. Wer lieber etwas anderes ansehen möchte, sollte es mit Ocean's Twelve versuchen - der coolste Film des Winters! Wer auf seichteren Humor steht, kann es auch getrost mit Trouble ohne Paddel versuchen (auch auf Baumgarf findet sich ein Review, jedoch wählt Ralf den Originaltitel Survival Camp, weil er den "deutschen" Titel nicht mag. Sich aber über den schleichenden Verfall des Deutschen beschweren, tsts. Heuchler ;)

Tech layoffs of 2022

Very interesting article reflecting on the current round of layoffs in the tech industry. The author explains it within the context of the wider economy. I'm surprised that the pandemic is not mentioned, which lead to accelerated growth early in the pandemic, which now hasn't turned out to be sustained. But the other arguments - from low interest rates to constant undervaluation due to the dot com bust around the millennium - this seems to tell a rather coherent story.

One particularly interesting point is the outlook that the tech company has gobbled up so much programming talent that other industries were starved of it. A lot of industries would benefit from (more modestly paid) software engineers, which might stimulate the whole economy to grow. Software might still be "eating the world", but that doesn't have to translate into software companies eating up the economy. There are so many businesses with domain expertise that cannot be easily replaced by some Silicon Valley engineer - but who would benefit from some programmers on staff.

This is especially true with the last decade of AI results. There is a massive overhang of capabilities that we have unlocked, which hasn't found its way into products yet, partly because all the skills necessary to turn these into products at the right places were just concentrated through enormously high wages in a small set of companies. There are so many businesses who would benefit from the latest machine learning methods. But folks prefer, understandably, to work in a place that gives them the promise of revolutionizing whole industries or saving the world.

But there is so much potential value to be generated if we also take some more modest goals into account. Not all of us need to work on AGI, it's also great to use software engineering skills to improve working conditions at the assembly line of a small local factory. With or without machine learning.

Temperatures in California

It has been a bit chillier the last few days. I noticed that after almost a decade in California, I feel pretty comfortable with understanding temperatures in Fahrenheit - as long as they are over 60° F. If it is colder, I need to switch to Celsius in order to understand how cold it exactly is. I have no idea what 40° or 45° or 50° F are, but I still know what 5° C is!

The fact that I still haven't acclimatised to Fahrenheit for the cooler temperatures tells you a lot about the climate in California.

Ten years of Wikidata

Today it's ten years since Wikidata had launched. A few memories.

It's been an amazing time. In the summer of 2011, people still didn't believe Wikidata would happen. In the fall of 2012, it was there.

Markus Krötzsch and I were pushing for the idea of a Semantic Wikipedia since 2005. Semantic MediaWiki was born from that idea, Freebase and DBpedia launched in 2007, microformats in Wikipedia became a grassroots thing, but no one was working on the real thing at the Wikimedia Foundation.

With Elena Simperl at KIT we started the EU research project RENDER in 2010, involving Mathias Schindler at Wikimedia Deutschland. It was about knowledge diversity on the Web, still an incredibly important topic. In RENDER, we developed ideas for the flexible representation of knowledge, and how to deal with contradicting and incomplete information. We analysed Wikipedia to understand the necessity of these ideas.

In 2010, I was finishing my PhD at KIT, and got an invitation by Yolanda Gil to work at the ISI at University of Southern California for a half year sabbatical. There, Yolanda, Varun Ratnakar, Markus and I developed a prototype for Wikidata which received the third place in the ISWC Semantic Web Challenge that year.

In 2011, the Wikimedia Data summit happened, invited by Tim O'Reilly and organised by Danese Cooper, to the headquarters of O'Reilly in Sebastopol, CA. There were folks from the Wikimedia Foundation, Freebase, DBpedia, Semantic MediaWiki, O'Reilly, there was Guha, Mark Greaves, I think, and others. I think that's where it became clear that Wikidata would be feasible.

It's also where I first met Guha and where I admitted to him that I was kinda a fan boy. He invented MFC, RDF, had worked with Douglas Lenat on CYC, and later that year introduced Schema.org. He's now working on Data Commons. Check it out, it's awesome.

Mark Greaves, a former DARPA program officer, who then was working for Paul Allen at Vulcan, had been supporting Semantic MediaWiki for several years, and he really wanted to make Wikidata happen. He knew my PhD was done, and that I was thinking about my next step. I thought it would be academia, but he suggested I should write up a project proposal for Wikidata.

After six years advocating for it, I understood that someone would need to step up to make it happen. With the support and confidence of so many people - Markus Krötzsch, Elena Simperl, Mark Greaves, Guha, Jamie Taylor, Rudi Studer, John Giannandrea, and others - I drafted the proposal.

The Board of the Wikimedia Foundation approved the proposal as a new Wikimedia project, but neither allocated the funding, nor directed the Foundation to do it. In fact, the Foundation was reluctant to take it on, unsure whether they would be able to host such a project development at that time. Back then, that was a wise decision.

Erik Möller, then CTO of the Foundation, was the driving force behind a major change: instead of turning the individual Wikipedias semantic, we would have a single Wikidata for all languages. Erik was also the one who had secured the domain for Wikidata. Many years prior.

Over the next half year and with the help of the Wikimedia Foundation, we secured funding from AI2 (Paul Allen), Google (who had acquired Freebase in the meantime), and the Gordon and Betty Moore Foundation, 1.3 million.

Other funders backed out because I insisted on the Wikidata ontology to be entirely under the control of the community. They argued to have professional ontologists, or reuse ontologies, or to use DBpedia to seed Wikidata. I said no. I firmly believed, and still believe, that the ontology has to be owned, created and maintained by the community. I invited the ontologists to join the project as community members, but to the best of my knowledge, they never made significant contributions. We did miss out on quite a bit of funding, though.

There we were. We had the funding and the project proposal, but no one to host us. We were even thinking of founding a new organisation, or hosting it at KIT, but due to the RENDER collaboration, Mathias Schindler had us talk with Pavel Richter, ED of Wikimedia Deutschland, and Pavel offered to host the development of Wikidata.

For Pavel and Wikimedia Deutschland this was a big step: the development team would significantly increase WMDE (I think, almost double it in size, if I remember correctly), which would necessitate a sudden transformation and increased professionalisation of WMDE. But Pavel was ready for it, and managed this growth admirably.

On April 1st 2012, we started the development of Wikidata. On October 29 2012 we launched the site.

The original launch was utterly useless. All you could do was creating new pages with Q IDs (the Q being a homage to Kamara, my wife), associated those Q IDs with labels in many languages, and connect to articles in Wikipedia, so called sitelinks. You could not add any statements yet. You could not connect items with each other. The sitelinks were not used anywhere. The labels were not used anywhere. As I said, the site was completely useless. And great fun, at least to me.

QIDs for entities are still being often disparaged. Why QIDs? Why not just the English name? Isn't dbp:Tokyo much easier to understand than Q1490? It was an uphill battle ten years ago to overcome the anglocentricity of many people. Unfortunately, this has not changed much. I am thankful to the Wikimedia movement to be one of the places that encourages, values, and supports the multilingual approach of Wikidata.

Over the next few months, the first few Wikipedias were able to access the sitelinks from Wikidata, and started deleting the sitelinks from their Wikipedias. This lead to a removal of more than 240 million lines of wikitext across the Wikipedias. 240 million lines that didn't need to be maintained anymore. In some languages, these lines constituted more than half of the content of the Wikipedia. In many languages, editing activity dropped dramatically at first, sometimes by 80%.

But then something happened. Those edits were mostly bots. And with those bots gone, humans were suddenly better able to see each other and build a more meaningful community. In many languages, this eventually lead to an increased community activity.

One of my biggest miscalculations when launching Wikidata was to entirely dismiss the possibility of a SPARQL endpoint. I thought that none of the existing open source triple stores would be performant enough. Peter Haase was instrumental in showing that I was wrong. Today, the SPARQL endpoint is an absolutely crucial piece of the Wikidata infrastructure, and is widely used to explore the dataset. And with its beautiful visualisations, I find it almost criminally underused. Unfortunately, the SPARQL endpoint is also the piece of infrastructure that worries us the most. The Wikimedia Foundation is working hard on figuring out the future for this service, and if you can offer substantial help, please reach out.

Today, Wikidata has more than 1.4 billion statements about approximately 100 million topics. It is by far the most edited Wikimedia project, with more edits than the English, German, and French Wikipedia together - even though they are each a decade older than Wikidata.

Wikidata is widely used. Almost every time Wikipedia serves one of its 24 billion monthly page views. Or during the pandemic in order to centralise the data about COVID cases in India to make them available across the languages of India. By large companies answering questions and fulfilling tasks with their intelligent assistants, be it Google or Apple or Microsoft. By academia, where you will find thousands of research papers using Wikidata. By numerous Open Source projects, by one-off analyses by data scientists, by small enterprises using the dataset, by student programmers exploring and playing with it on the weekend, by spreadsheet enthusiasts enriching their data, by scientists, librarians and curators linking their datasets to Wikidata, and thus to each other. Already, more than 7,000 catalogs are linked to Wikidata, and thus to each other, really and substantially establishing a Web of linked data.

I will always remember the Amazon developer who approached me after a talk. He had used Wikidata to gather data about movies. I was surprised: Amazon owns imdb, why would they ever use anything else for movies? He said that imdb was great for what it had, but Wikidata complemented it in unexpected ways, offering many interesting connections between the movies and other topics which would be out of scope for imdb.

Not to be misunderstood: knowledge bases such as imdb are amazing, and Wikidata does not aim to replace them. They often have a clear scope, have a higher quality, and almost always a better coverage in their field than Wikidata ever can hope to have, or aims to have. And that's OK. Wikidata's goal is not to replace these knowledge bases. But to provide the connecting tissue between the many knowledge bases out there. To connect them. To provide a common set of entities to work with. To turn the individual knowledge bases into a large interconnected Web of knowledge.

I am still surprised that Wikidata is not known more widely among developers. It always makes me smile with joy when I see yet another developer who just discovered Wikidata and writes an excited post about it and how much it helped them. In the last two weeks, I stumbled upon two projects who used Wikidata identifiers where I didn't expect them at all, just used them as if it was the most normal thing in the world. This is something I hope we will see even more in the future. I hope that Wikidata will become the common knowledge base that is ubiquitously used by a large swarm of intelligent applications. Not only to make these applications be smarter, by knowing more about the world - but also by allowing these applications to exchange data with each other more effectively because they are using the same language.

And most importantly: Wikidata has a healthy, large, and comparatively friendly and diverse community. It is one of the most active Wikimedia projects, only trailing the English Wikipedia, and usually similarly active as Commons.

Last time I checked, more than 400,000 people have contributed to Wikidata. For me, that is easily the most surprising number about the project. If you had asked me in 2012 how many people would contribute to Wikidata, I would have sheepishly hoped for a few hundred, maybe a few thousand. And I would have defensively explained why that's OK. I am humbled and awestruck by the fact that several hundred thousand people have contributed to an open knowledge base that is available to everyone, and that everyone can contribute to.

And that I think is the most important role that Wikidata plays. That it is a place that everyone can contribute to. That the knowledge base that everyone uses is not owned and gateguarded by any one company or government, but that it is a common good, that everyone can contribute to. That everyone with an internet connection can lend their voice to the sum of all knowledge.

We all own Wikidata. We are responsible for Wikidata. And we all benefit from Wikidata.

It has been an amazing ten years. I am looking forward to many more years of Wikidata, and to the many new roles that it will play in the years to come, and to the many people who will contribute to it.

Shoutout to the brilliant team that started the work on Wikidata: Lydia Pintscher, Abraham Taherivand, Daniel Kinzler, Jeroen De Dauw, Katie Filbert, Tobias Gritschacher, Jens Ohlig, John Blad, Daniel Werner, Henning Snater, and Silke Meyer.

And thank you for all these amazing pictures of cakes for Wikidata's birthday. (And if you're curious what is coming next: we are working on Wikifunctions and Abstract Wikipedia, in order to allow more people to contribute more knowledge to even more people!)
