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
6
™
SemWebCentral.org
 Open source software
repository based on
GForge
 145 projects, 854 users
 Still maintained at BBN
 Hardware and software
upgrade in progress
7
™
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
