Complex Relationships for the Semantic Web

Introduction Relationships are fundamental to supporting semantics [Wie97, She96], and hence to the Semantic Web [LHL, FM01 ]. Till date, focus has been on simple relationships such as isa and is-part-of, as in DAML/OIL [Ont]. In this work, we adapt our earlier work on MREF [SS98] to develop a framework for supporting complex relationships. A framework to manage complex relationships as discussed here becomes the basis for knowledge discovery from the information interlinked by the Semantic Web. Our work primarily builds upon earlier research in integrating information systems that has also been applied to exploiting web-accessible distributed across heterogeneous information sources. Primary focus of information integration systems has been to model these diverse data sources and integrate the data by resolving the heterogeneity involved to provide global views of domains (one point access) for querying. We shift the focus from modeling of the information sources for purpose of quer
