Abstract

Converting web data to semantic format is an important task for the next generation of the web. A huge amount of web data is stored in databases. Moreover, many approaches are proposed to map between DB and web ontologies. This paper proposes an approach to convert DB to RDF with extra user-defined rules. These extra rules, which extend the original data, enable semantic query engines to answer more queries. The proposed approach generates RDF data, which represents not only the original relational database but also extra discovered relations based on user defined rules. A prototype for the proposed approach is applied on a large database to show the effectiveness of the proposed idea.
