I'm a member of the USC/ISI Information Integration Research Group and the USC Computer Science Database Group.

Current Projects

• Argos focuses on automatic web service composition (applied to a transportation planning domain).
• EntityBases is developing techniques to extract, link, and integrate massive amounts of data from numerous heterogeneous sources.
• CALO (Cognitive Assistant that Learns and Organizes): working on facilitating information integration by learning source models.
• Heracles is an interactive data-driven constraint-based hierarchical planner.

Past Projects

• SIMS and Ariadne are mediator architectures that integrate information from distributed and heterogeneous data sources.
• The DGRC Energy Data Collection EDC project integrates information from government databases and extends the integration framework of SIMS by leveraging large ontologies such as SENSUS (now OMEGA ) and natural language processing techniques.
• Proteus focuses on web service composition and execution.
