Toward the semantic web - An approach to reverse engineering of relational databases to ontologies

Abstract

We propose a novel approach to reverse engineering of relational da-tabases to ontologies. Our approach incorporates two main sources of seman-tics: HTML pages and a relational schema. This incorporation results in that: (1) only minimal information about a relational database is required to build an ontology; and (2) the ontology is no longer "impaired" by bad-database design, and by optimization and de-normalization of the relational schema. Our ap-proach can be used for migrating HTML pages (especially those that are dy-namically generated from a relational database) to the ontology-based Semantic Web. The main reason for this migration is to make the relational database in-formation that is available on the Web machine-processable.
