Logic Inference-Based Semantic Web Service for KB Retrieval

Because the ontology-based knowledge base is distributed and heterogeneous, a logic inference-based semantic Web service is presented in this paper. By use of the query converter, the service can retrieve the knowledge base by logic inference. Then the service can retrieve each distributed knowledge base independently and by the unified interfaces supplied by the service, the problem of heterogeneity becomes transparent for other services. The experiments show that this service is very perfect in retrieving the knowledge base.
