摘　　要：实现基于功能语义的Web服务过滤是简化服务检索计算量、提高服务发现准确率的有效方法之一。针对现有常用Web服务描述语言不能很好地支持服务基于功能的语义描述的问题,通过定义服务功能描述模型,构建领域功能本体,提出了一种基于功能语义的Web服务描述方法,并详细给出了基于OWL-S的实现,在此基础上,给出了一种服务预检索方法。该方法可有效地支持用户实现基于功能的语义服务检索,滤除无关服务,降低精确匹配计算量,提高服务查找效率。Functional semantic based Web service filter is a useful method to decrease the computation of service discov- ery. According to the problem that current semantic-based services description languages can not support service func- tional description, this paper firstly defined a functional based Web service semantic description model and created a do- main oriented functional ontology. Based on this, a service description method was raised and a realize method based on OWL-S was expressed clearly. Finally a pre-filter method was raised. The pre-filter method can support the service dis- covery based on functional semantic, filter out unrelated services, decrease the computation of accurate service match and increase the matching efficiency.
