Abstract

Over the past decade there is an increase in requirement of web application, and to the most of the web application relational schema is attached as a backend. The idea of semantic web was presented by Tim Berners-Lee, and it has captured the focus of many researchers in past few years. The promises of future web have brought the researchers to the point where to obtain the benefits of future web; we need to make conversion of current web i.e. web 2.0 to future Web i.e Semantic Web. There will be relational schema to ontology conversion required while making such transitions. There is a need to have some automated or semi automated approach for this issue as it will be hard to convert relational schema to ontology manually. The paper discusses some of the available techniques for the conversion, and focuses on the foreign key identification in the relational schema then compares some already presented techniques and concludes the results on the experimentation carried out on different relational schemas.
