摘要：Web service collaboration is a feasible solution for complicated task resolving. To reach high performance collaboration, sponsor requires competent participants. In this article, we propose an ability evaluation based selection methodology for candidate web services. The ability of web service can be evaluated from four aspects: time, resource, goal and quality. We first propose the formal semantic descriptions of both web service ability and task. Then, the evaluation methods of time, resource, goal and quality are addressed, and the comprehensive ability evaluation is calculated through above four aspects' evaluation. Furthermore, service selection process, which is consists of three stages: task publishing, ability evaluation and service negotiation, is presented. Finally, examination showed that the selection method given in this paper is effective. © 2011 IEEE.
