摘要: 提出一种新型Overlay网络服务发现机制,该机制充分利用概念之间的语义相似性,从语义概念树模型扩展概念相似度的计算,并将该语义概念树模型应用到Overlay网络服务发现机制的研究中。实验证明,该语义概念模型能够根据用户的想法和查询词条的内在含义进行相近语义短语的查找,实现匹配机制的语义化,提高了服务发现的查准率。

Abstract: A method is presented to discover Overlay Web service based on semantic model. The method uses the semantic similarity among concepts, broadens the calculation of concept similarity by semantic concept tree model and applies the model in Overlay networks service discovery method. Experimental results demonstrate that the semantic model could find similar terms by the meaning and realize semantic matching. The method promotes discovery precision.

Key words: semantic model, Overlay networks, service discovery, concept tree
