摘要: 针对集中式的语义服务发现机制成为服务发现和匹配时的瓶颈问题,结合P2P和聚类的思想,探讨一种基于P2P的Web Services聚类与组合模型。理论分析与仿真实验表明,该模型在Web Services的匹配速度和查准率上均有提高,可以为用户提供由Web Services组合而成的增值服务,在一定程度上解决了集中式的语义服务发现机制在面向服务计算过程中的瓶颈问题。

Abstract: For the problem that the centralized mechanism for semantic service discovery is becoming a choke point during service discovery and matching, a novel model of Web Services is proposed which makes use of some ideas from the peer-to-peer technology and the clustering method. Both theoretical analysis and simulation results show that this model is able to improve the matching speed as well as to raise the precision, and moreover, it can provide users with of value-added response from Web Services combination, and also deal with the problem of the centralized mechanism for semantic service discovery during the service-oriented computation.

Key words: P2P technology, clustering, Web Services, services composition
