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 study of OWL-S, aiming at the shortcomings of OWL-S, this paper extends OWL-S effectively and adds quality description information such as location information and time, cost and reliability to obtain an extended semantic Web Services Description Model --OWL-S +. Aiming at the OWL-S + model, a matching strategy that takes service and quality performance into account and improves the matching efficiency is proposed. Finally, through an example, the discovery of transportation construction project quality inspection and evaluation service, it proves the validity of OWL-S + model and matching strategy.
