SIMS II: Single Interface to Multiple Sources of Incomplete Information

Abstract

With the current explosion of data, retrieving and integrating information from various sources is a critical problem. This report describes work performed at USC/ISI, aimed at developing a general and extensible approach to this problem, with attention paid also to cases where knowledge of the ultimate sources is incomplete or inaccurate. The SIMS approach exploits a semantic model of a problem domain to integrate the information from various sources; databases, knowledge bases and more. The domain and the information sources are modeled. Queries submitted to SIMS are mapped into a set of queries to individual information sources. The data obtained is then returned to the user. SIMS utilizes techniques from the areas of knowledge representation, planning, learning, and data mining.
