摘　　要：针对Web服务发现中存在的语义异构、逻辑推理复杂、应用实施代价较大以及查准率有待进一步提高等问题,提出了一种基于功能语义标注的Web服务发现方法。定义了领域功能语义模型和本体映射机制,对服务进行功能语义标注以增加语义信息;服务发现时,先对其功能进行语义相似度匹配,满足给定阈值的服务再进行接口匹配。仿真实验表明,提出的方法在保证服务匹配效率的同时,有效避免了语义异构问题,相比传统方法查准率提高了34.1%。Aiming at the existing problems in Web service discovery such as semantic heterogeneity,complexity of logical reasoning,much cost to implement,and the precision can be further improved,this paper presented a Web service discovery approach based on functional semantic annotation.Defined a Web service domain functional semantic model and the correspon-ding mapping mechanism,added functional semantic information to Web service by annotating the function of Web service.During the service discovering,firstly matched services according to the function using semantic similarity,then discovered according to the interface only with the results that satisfied the given threshold.A serial of experiments illustrate that the method improves the service matching efficiency,effectively avoids semantic heterogeneity,and compared with the traditional method the precision increases by 34.1%.
