Abstract:

With the current explosion of data, retrieving and integrating information from various sources is a critical problem. This report describes work performed at USCISI, aimed at developing a general and extensible approach to this problem. The SIMS approach exploits a semantic model of a problem domain to integrate the information from various sources, i.e., databases and knowledge bases. The domain and the information sources are modeled. Queries submitted to SIMS are mapped into a set of queries to individual information sources. The set of queries is then further optimized, using knowledge, about the domain and the information sources. The data obtained is then returned to the user. SIMS utilizes techniques from the areas of knowledge representation, planning, and learning
