The Method of Concept Similarity Computation in Taxonomy Ontology

This paper describes a method to calculate the concept similarity in taxonomy ontology and help searching system of E-commerce to answer users’ query more effectively. Instead of using the current ontology mapping methods which are focus on analyzing the terms’ relationship based on some thesauruses and special construction definition of terms, in this paper we firstly show the creation of taxonomy ontology, and then based on it, we describe a method to calculate the similarity between terms in the taxonomy ontology and terms in source ontology. Following with this method, the similarity can be calculated and used in answering users’ queries. Finally, this paper supplies an instance to validate this method.
