Abstract:
Semantic Web sets the standard for a universal and interoperable data representation that is not only readable to the naked eye but also to computers. The use of Uniform Resource Identifier (URI) and the capability to use description logic through semantic ontology languages makes semantic web the favoured framework to represent knowledge. Semantic Web standards play a vital role in making the existing relational database, which is locked behind in the “deep web”, available for computer processing. In order to map the relational database in its entirety, the methodology should not only map the data but also the domain specific knowledge. The algorithms and their implementation presented in this paper use the meta-data from the data dictionary to construct the initial semantic repository, while using domain specific knowledge during in-processing stage.
