基于本体和QoS的面向敏捷供应链知识服务匹配研究


  摘 要:为了加强面向敏捷供应链的知识服务的服务描述信息的机器可理解性,提高用户需求和服务能力之间功能匹配的准确性,在总结和分析相关服务发现和匹配算法的基础上,提出了一个基于扩展OWL-S和服务质量QoS的知识服务描述模型。提出一种基于本体计算语义相似度的方法,利用此方法实现服务的功能性匹配。最后用一个服务匹配实例说明了该匹配算法在充分考虑用户需求方面的有效性。

  Abstract:In order to strengthen the machine-understanding of description of services in agile supply chain-oriented knowledge services and increase the accuracy of matching between user needs and services capabilities, on the basis of summarizing and analyzing the relevant service discovery and matching algorithms, this paper proposed a knowledge services description model based on the expansion of the OWL-S and QoS. Besides, it also proposed an algorithm of calculating semantic similarity based on ontology, made using of which the functional matching was achieved. At last, it used a service matching example to illustrate the effectiveness of this matching algorithm in taking full account of user needs.
