™ Copyright ©2009 BBN Technologies 5 Semantic BBN  Research –DARPA Agent Markup Language (DAML) –Geospatial –Prediction –Machine Learning  Tools –Parliament –Snoggle –Asio Scout TM  Collaboration –semwebcentral.org –Peer-reviewed papers, conference sponsorship, and books... –Working groups  Applications –Broad range of government and commercial applications from research explorations to production deployment Innovation Loop

™ Copyright ©2009 BBN Technologies 6 The Digital Whitewater Challenge  Volume –~ 8 exabytes/month –AT&T alone – 18 petabytes/day –youtube alone is now more than all Internet traffic in 2000  Variety –Modes: 40% video –Formats: IM, , Blogs, XML, –Places: MySpace, Facebook, Second Life, Darkweb... –Trillion unique URLs –Fractal – Laptop, Enterprise, WWW  Velocity –38 minutes to find one document –10 second lead worth millions/lives  BUT... –Is it true? –Is it useful? –Can you find it in time?

™ Copyright ©2009 BBN Technologies Semantic Web Application Lifecycle  Model Creation Ontology Development Mapping Sense Making  Steady State Identify Outliers Model Adaptation

™ Copyright ©2009 BBN Technologies Data Integration  Many of our applications focus on some aspect of data integration Diverse databases, web services Combining structured and unstructured information (RDF encoding of natural language processing output) Translation between ontologies using SWRL plays a key role in many of our solutions Presentations at SemTech 2007 and

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” Catch the SemTech-2009 talk Thurs. 6/18 9:45-10:45am presented by Benjamin Grosof, Vulcan Inc.
