DAML
BBN was the Integration and Transition Contractor for the DARPA Agent Markup Language (DAML) program, 2000-2005– Coordinated the efforts of 25 research teams– Led the Joint US/EU ad hoc Agent Markup
Language Committee, participated in W3C RDF Core and Web Ontology Working Groups
– Developed a number of tools, data sets, and applications
– Maintained daml.org and SemWebCentral.org

Open source software repository based on GForge
145 projects, 854 users Still maintained at BBN Hardware and software
upgrade in progress

R&D
DAML was the first and last large US Semantic Web research program– The DARPA Director thought we were “done”
once OWL became a W3C Recommendation Smaller R&D efforts in other agencies Several DARPA “seedling” projects Our focus has shifted to applications using
the Semantic Web (explicitly or not)– Government and commercial
8
™
Data Integration
Many of our applications focus on some aspect of data integration– Diverse databases, web services– Co-reference resolution among incomplete data sets
• Which of 500 references to John Smith refer to the same person?
– Combining structured and unstructured information (RDF encoding of natural language processing output)
– Translation between ontologies using SWRL plays a key role in many of solutions
