一种需求驱动的自主Web服务聚集方法

Approach for Autonomous Web Service Aggregation Driven by Requirement

引入具有主动搜索需求能力的自主Web服务概念,提出基于环境本体的意图-行为-实现机制,用于描述服务请求和自主Web服务能力,构型了一种需求驱动的自主Web服务聚集的模型.给出了基于意图-行为-实现机制的需求能力匹配算法和自主Web服务聚集算法.最后,通过对应用案例的研究来展示该方法的可行性.

A new concept,Autonomous Web Service （AWS）,to search requirement autonomously,is introduced in this paper.An intention-behavior-achievement mechanism based on environment ontology is proposed to specify the service request and the capability of AWS.A model of AWS aggregation driven by requirement has been figured out.The matching algorithm between the requirements and the AWS capability and the AWSs aggregating algorithm have been designed based on the intention-behavior-achievement mechanism.Finally,a case study is given to show the feasibility of this method.
