Research on Ontology-Based Semantic Similarity Computation

This paper we present a method for computing similarity between different concepts. Ontology has the good hierarchical structure of concepts and the support of logical reasoning, and semantic information can be realized through the semantic relationship of concepts. Ontology technology can be well applied to information retrieval. Ontology-based information retrieval is different from the traditional keyword search. Semantic retrieval can be realized because Ontology knowledge base strengthens the intrinsic link of the concepts and the implied and unclear information can be deduced through logical reasoning. Our results show that the general framework is feasible and this method is applicable across different concepts.
