Research of Transactions Goods Domain Ontology Building Method Based on Reputation Recommendation Trust Model

In reputation recommendation system of E-Commerce, while two recommendation nodes recommended the same node, their transactions goods content similarity could be used to judge the credibility of their recommendation, so concept similarity of transactions goods domain ontology could be used to a computing method of transactions goods content similarity, transactions goods domain ontology need be created firstly in order to obtain similarity between theirs. This paper proposes a hierarchical building method for trade goods domain ontology based on types and key attributes. Through top-down ontology analysis and design as well as bottom-up ontology building and integration, this method can quickly build a prototype of trade goods domain ontology, then ontology is recreated, according to experts´ evaluations, and forms a complete trade goods domain ontology ultimately.
