摘　　要：在研究语义Web描述模型OWL-S基础上,针对OWL-S的缺点,对OWL-S进行了有效扩展,增加了地域位置信息和时间、费用、可靠性等质量描述信息,得到一个扩展的语义Web服务描述模型--OWL-S+。针对OWL-S+模型,提出了一种综合考虑服务功能和质量性能的、有助于提高匹配效率的匹配策略。最后通过一个实例-交通建设项目质量检验与评估服务的发现证明了OWL-S+模型和匹配策略的有效性。Based on the analysis of semantic Web description model （OWL-S）, an extended OWL-S model （named as OWL-S＋ ） is put forward according to the shortcoming of the OWL-S model. The OWL-S ＋ adds 5 attributes of describing quality information, zone area, time, cost and reliability. On the basis of extended OWL-S＋ , an efficient matching strategy is proposed in order to improve efficiency of matching between the requests and the services. The matching strategy takes the performance and quality of service into consideration. Finally, the advantage of the OWL-S ＋ and matching strategy is proved by a Semantic Web Service Discovery application-Transportation Construction Project Quality Inspection and Appraisal Services Discovery-OWL-S ＋.
