Hiya, I'd like to point folks to some informative posts concerning DL Safe SWRL rules and a kind of Uncertainty extension to OWL. These, I imagine, shall be inputs to the Rules task force and the Uncertain OWL task forces. Both are ongoing. Rules: http://clarkparsia.com/weblog/category/semweb/rules/swrl/ Pronto (Probabilistic Pellet): http://clarkparsia.com/weblog/category/semweb/probabilistic-reasoning/ (Both are in reverse chronological order...sorry :)) The Pronto series is being written by Pavel Klinov which Clark & Parsia,LLC has the great good fortune to have as an intern this summer. Pavel did the extension to Pellet he describes in these posts. We've not yet figured out how we're going to let folks get their hands on it, but we're working on it :) The other interesting bit is how we used axiom annotations to extend OWL with probabilities. (hence touching on the rich annotation task force). This is a bit of a risky move in the sense that the probability annotations are definitely a "must-understand" kind of extension. There isn't a good drop back if you ignore them. I've been playing with using annotations for an OntoClean extension, but there I think ignoring the OntoClean annotations is a safe thing to do for many purposes. I think it'd be nice if the annotation system gave us some of this sort of extensibility. Enjoy. Cheers, Bijan. P.S., OWLED TaskForces: http://code.google.com/p/owl1-1/wiki/TaskForces As you can see, they are starting to heat up a bit. The controlled natural language page has some good stuff. If you are interested in working on any of these tasks, contact the point person. I'm using subject tags for easier filtering...I hope that's ok.
