CDL-based Semantic Representation for Web Databases

One important task toward making web machine understandable is representing web data into semantic formats. Since a huge amount of web data stored in databases, researchers pay much care to convert DB to semantic format. Most of the previous work depends on domain ontology to covert DB to RDF. However, depending on domain ontology has many problems. This paper proposes converting web DBs into CDL semantic format, which does not depend on domain ontology. In addition, CDL describes semantic structure of web content based on a set of predefined concepts and semantic relations. The first step to convert DB to CDL is representing DB schema into a semantic network. The second step is automatic generation for CDL based on the semantic network. A prototype is presented to show the effectiveness of the proposed approach. Semantic represenation, semantic database, Concept Description Language
