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...

ACM Review II

Thanks to Mary-Lynn Bragg for answering my complaint about non-accessible reviews so quickly. She sent me the review to read, and I was quite happy with it. Michael Lesk, one of the guys who built Unix, wrote the review, and recommended it to "designers of volunteer or collaborative systems and [...] those studying cooperative work.". Thanks, Michael, thanks Mary-Lynn.

Sooo -- read our straightforward and easy to read paper! :)

By the way -- I still think ACM Computing Reviews should offer their reviews for free to the public. This would increase the impact of their reviews dramatically, and also the impact of the reviewed papers.

Wikimania 2006 is over

And it sure was one of the hottest conferences ever! I don't mean just because of the 40°C/100°F that we had to endure in Boston, but also because of the further speakers there.

Brewster Kahle, the man behind the Internet Archive, and who started Alexa and WAIS Inc., told us about his plans to digitalize every book (just a few Petabytes), every movie (just a few Petabytes), every record (just a... well, you get the drill), and to make a snapshot of the web every few months, and archive this. Wow.

Yochai Benkler spoke about the Wealth of Networks. You can download his book from his site, or go to a bookstore and get it there. The talk was really inviting to read it: why does a network thingy like Wikipedia work and not suck? How does this change basically everything?

Next day, there was Mitch Kapor, president of the Open Source Application Foundation -- and I am really sorry I had to miss his talk, because at the same time we were giving our workshop on how to reuse the knowledge within a Semantic MediaWiki in your own applications and websites. Markus Krötzsch, travel companion and fellow AIFB PhD student, and basically the wizard who programmed most of the Semantic MediaWiki extension, totally surprised me by being surprised about what you can do with this Semantic Web stuff. Yes, indeed, the idea is to be able to ask another website to put stuff up on yours. And to mush data.

There was David Weinberger, whose talk made me laugh more than I had for a while (and I am quite merry, usually!). I still have to rethink what he actually said, contentwise, but it made a lot of sense, and I took some notes, it was on the structure of knowledge, and how it changes in the new world we are living in.

Ben Shneiderman, the pope on visualization and User Interfaces had an interesting talk on visualizing the Wikipedia. The two talks before his, by Fernanda Viegas and Martin Wattenberg, were really great, because they have visualized real Wikipedia data -- and showed us a lot of interesting data. I hope their tools will become available soon. (Ben's own talk was rather a bit disappointing, as he didn't seem to have the time to take some real data, but only used fake data to show some general possible visualizations. As i had the chance to see him in Darmstadt last year anyway, I didn't see much new stuff).

The party at the MIT Museum was great! Even though I wasn't allow to drink, because I forgot my ID. I'd never think anyone would consider me looking younger than 21. So I take this as the most sincere compliment. Don't bother explaining they had to check my ID even if I looked 110, I really don't want to hear :) I saw Kismet! Pitily, he was switched off.

Trust me. I was kinda tired after this week. It was lots of fun, it was enormously interesting. Thanks to all the Wikipedians, who made Wikipedia and Wikimania possible. Thanks to all these people for organizing this event and helping out! I am looking forward to Wikimania 2007, wherever it will be. The bidding for hosting Wikimania 2007 are open!

ACM Review

ACM Computing Reviews reviewed our paper on the Semantic Wikipedia. Yay! Pitily, I can't read the review because I need a login.

Would love to see what they're saying, but I guess it's not meant to be open to the public. Or to the authors.

Maybe the hottest conference ever

The Wikipedia Hacking Days are over. We have been visiting Siggraph, we had a tour through the MIT Media Lab, some of the people around were Brion Vibber (Wikimedia's CTO), Ward Cunningham (the guy who invented wikis), Dan Bricklin (the guy who invented spreadsheets), Aaron Swartz (a web wunderkind, he wrote the RSS specs at 14), Jimbo Wales (the guy who made Wikipedia happen), and many other people. We have been working at the One Laptop per Child offices, the office to easily the coolest project of the world.

During our stay at the Hacking Days, we had the chance to meet up with the local IBM Semantic Web dev staff and Elias Torres, who showed us the fabulous work they are doing right now on the Semantic Web technology stack (never before rapid application deployment was so rapid). And we also met up with the Simile project people, where we talked about connecting their stuff like Longwell and Timeline to the Semantic MedaWiki. We actually tried Timeline out on the ISWC2006 conference page, and the RDF worked out of the box, giving us a timeline of the workshop deadlines. Yay!

Today started Wikimania2006 at the Harvard Law School. was not only a keynote by Lawrence Lessig, as great as expected, but also our panel on the Semantic Wikipedia. We had an unexpected guest (who didn't get introduced, so most people didn't even realize he was there), Tim Berners-Lee, probably still jetlagged from a trip to Malaysia. The session was received well, and Brion said, that he sees us on the way of getting the extension into Wikipedia proper. Way cool. And we got bug reports from Sir Timbl again.

And there are still two days to go. If you're around and like to meet, drop a note.

Trust me — it all sounds like a dream to me.

Wikimania 2006

I am here in Boston now, walking the sacred grounds of Harvard and MIT, and listening and talking with the great people who created the MediaWiki software that runs Wikipedia. At Thursday, Markus and I will host the Semantic Wikipedia panel, where we present the state of our implementation, and talk about how to make it real. We also have a tutorial on Sunday, about how to reuse knowledge from a Semantic MediaWiki.

If you're around Boston, MIT, Harvard, or if you even attend Wikimania and the Hacking Days, and want to meet -- contact me!
