Automatic Migration From Imperfect Relational Database To Resource Description Framework

Abstract

The existing data on the web is growing increasingly diverse and extensive. Unfortunately, most of the current data is not semantic web friendly. The relational database (RDB) is considered one of the most popular structured data models. This work aims to automatically migrate from an imperfect RDB to a resource description framework (RDF). This issue has been ignored by previous work. Imperfectness means the lack of constraints in RDB. We attempt to construct an algorithm to migrate the RDB (including imperfect ones) to RDF. Results and evaluation showed that the proposed algorithm has succeeded in finding the relationship in RDB and migrating the RDB to RDF.
