摘要
目前基于本体的Web服务匹配方法主要是利用本体的逻辑推理能力,通过计算得到Web服务描述之间的离散值匹配度并实施服务匹配。但基于离散值的粗粒度划分会使每一个离散匹配度下可能仍会有大量的Web服务存在,无法满足用户精确的服务查找请求。在相关研究基础之上,提出了一种基于本体的多模式Web服务匹配策略,并给出了基于实体和功能性的相似度计算方法。通过将基于离散值的逻辑推理服务匹配和基于连续值的服务相似度计算相结合,从而得到服务请求与可用服务的综合相似度,满足了用户不同粒度的服务查找请求,增强了服务匹配过程的可适应性和有效性。
At Present, the main approach for web services matching based on ontology is to use the logic inferring capability of ontology, implement the service matching based on the discrete value which was calculated between the service description. The coarse granularity partition caused there were many web services still exists under every discrete mathcing degree, which can not fulfill the accurate service research. Based on relative research, an ontology-based multimode web services matching approach is proposed and the entity-based and functional-based similarity calculating method is introduced respectively. We can get the comprehensive similarity between service request and available services by put the deductive matching and similarity calculation together. The proposed approach fulfills the service request at multiple levels of granularity for different users, so that the flexibility and effectiveness of the matching process are greatly enhanced.
