A New Ontology-based Information Retrieval Method
Mass heterogeneous and unstructured web data makes it difficult to find necessary information. Using Web service technology, this article proposes a method of building metadata registry( MDR) and ontology management system(OMS) based on the semantics of metadata and ontology. By producing distributed closure, the search engine(SBWSE) uses an ontology representing language RDF, achieves high efficient access to distributed heterogeneous data, and solve the problem of incomplete and incorrect search results.
