一种基于本体的Web服务信任度计算模型
Trust computation model based on ontology for Web service
摘要
Abstract
The trust degree gotten by the traditional trust models is usually a single value and lacks context information,which makes its implication be ambiguous.Besides,these models are generally restricted in certain domain.As a result,trust computation can't be fulfilled due to the absence of common knowledge between domains.To solve these problems,this paper proposed a trust computation model based on context ontology for Web service.Ontology technology facilitated the expression and inference for context information and provided the shared knowledge base for different domains.In the proposed model,the context information concerned by user was taken as the decisive factors to compute the indirect trust degree.On the basis of semantic matching for context concepts,trust computation cross domains was finally realized.Experimental results validates the feasibility and effectivity of the model.关键词
