15. A new, highly ambitious effort by Vulcan Inc., which also develops Semantic MediaWiki+ and venture invests in sem tech. Multi-institutional. Addresses fundamental requirements for scaling Semantic Web to widely-authored Very Large KBs in business and science that answer questions, proactively supply info, and reason powerfully. A knowledge representation (KR) system: reasoner, language, UI, interchange. Radically extends the KR power of W3C OWL, SPARQL, and RIF – and of SQL Defaults and robust conflict handling – cope with knowledge quality and context Higher-order and flexible meta-reasoning – elevate meta-data to meta-knowledge Actions and events, cf. production rules and process models – activate knowledge Use cases in business policies, ontology mapping, e-commerce, biomed. Redefining the KR playing field for semantic web, business rules, and rule-based process management. How You can be Involved: In ~ fall 2009: try out SILK software; comment on SILK language design Visit the SILK webpage, subscribe to (rare) announcements, cooperate in other ways “Semantic Rules Take the Next Big Step in Power” http://silk.projects.semwebcentral.org Catch the SemTech-2009 talk Thurs. 6/18 9:45-10:45am presented by Benjamin Grosof, Vulcan Inc.
