DTD2OWL2: A New Approach for the Transformation of the DTD to OWL

The expansion of data sources existed in the web affects on the quality of research information. The correct answer (answer specific) of a request is all depend terms selected for their construction. Such as these terms sometimes mean more sense, the intended meaning may not be found. Fort this need, the Semantic Web has come to cover the semantic level, it proposed an ontological representation of data sources. This representation is implemented by OWL (Web Ontology Language). The current challenge of the Semantic Web is the transformation of data formats exist (SQL, XML ...) to the form of ontology (RDF, OWL ...), in order to facilitate the integration of data sources exist in the semantic web. Our target is to provide a series of extension concepts of DTD2OWL method, a simple and effective method for transforming XML documents into OWL ontologies.
