Multi-Ontology Query Based on Ontology Matching
Tan Yi · Computer Technology and Development · 2008
With the development of semantic web,ontology has become the main method of expressing knowledge in many areas.According to their own demand,many areas have established ontologies to describe knowledge of their own area.However,current semantic query of ontology can only query from a single ontology and return appropriate results.To realize a query system that can access many ontologies and return appropriate results,proposed a multi-ontology query method based on ontology matching.The ontology matching algorithm is multi-strategy one,combined based on semantics.The result of experiments shows that the time of excecuting query is in line with the number of ontologies,and does not increase with the heterogeneous of ontologies.
