I don’t have a whole lot more to say about Semantic MediaWiki than I said over a year ago. The summary is to turn the universal encyclopedia into the universal database while simultaneously improving the quality of the encyclopedia.
Flip through Denny Vrandecic’s recent presentations on Semantic MediaWiki (a smaller pdf version not directly linked in that post). There’s some technical content, but flip past that and you should still get the idea and be very excited.
I predict that Semantic MediaWiki also will be the killer application for the Semantic Web that so many have been skeptical of.
Yaron Koren also says that Semantic MediaWiki is “the technology that will revolutionize the web” and has built DiscourseDB using the software. DiscourseDB catalogs political opinion pieces. Koren’s post on aggregating analysis using DiscouseDB. Unsurprisingly this analysis shows the political experts making bad calls.
Koren also has created Betocracy, another play money prediction market where users create claims. It looks like Betocracy is going for a blog-like interface, but I can’t say more as registration obtains a database error.
One prediction market and Semantic MediaWiki connection is that making data more accessible makes prediction markets more feasible. Obtaining data necessary to create and judge prediction market contracts is expensive.
