目前中文搜索引擎尚不能进行语义检索,经OWL—S语义扩展后的语义Web服务检索也未充分考虑中文词语之间无空格的特点。基于语义Web服务技术与中文分词技术,提出基于中文分词的OWL—S/UDDI语义Web服务检索模型。该模型对中文检索请求语句进行中文分词并附加语义,所生成的服务请求OWL—S文档与语义扩展UDDI中的OWL—S服务描述进行匹配,进而实现Web服务的动态查找与组合。实验结果表明,语义Web服务检索可提高Web服务发现的质量。
Semantic retrieval could not be done in the current Chinese search engine, and the character of Chinese without spacing between words has not been considered in semantic web service retrieval after OWL-S semantic expansion. On the basis of the techniques of web service and Chinese word segmentation, the OWL-S/UDDI semantic web service retrieval model based on Chinese word segmentation is proposed. In this model, the service request OWL-S documents generated by Chinese word segmentation and the semantic expansion match with the OWL-S descriptions of web service in semantic expansion of the UDDI, consequently, the dynamical searching and composition of web services are implemented. The experimental results show that the quality of web service discovery can be improved by the semantic web service retrieval.
