Research on development and application of OWL ontology search middleware

This paper introduces an OWL ontology search middleware and an ontology search service system to demonstrate the functions of the middleware. The middleware can be used to search multiple ontologies at same time, with complex query conditions. Without a deep understanding of ontology’s structure knowledge and ontology query language, a general user can search ontologies just by inputting keywords with the help of the system. The middleware provides an easy way to search ontologies.
