【摘要】 通过把Web服务抽象成为具有输入和输出接口的实体,提出了基于接口匹配的Web服务组合方法.以当前标准-WSDL(Web Services Description Language,简称WSDL)作为服务接口的描述语言,从消息参数名和数据类型两方面通过使用聚类技术,将操作中的参数名归类为具有语义的概念,结合现有的WordNet语义词典,提出了服务接口匹配算法。该算法通过计算服务接口之间的相似程度,找出潜在的消息依赖关系,能够自动、动态地发现潜在的Web服务,从而实现Web服务自动组合。最后,在TRP系统上对匹配算法进行了实验评估。更多还原

【Abstract】 This paper proposes a novel automatic Web service composition method based on interface matching, by abstracting Web service as an entity with input and output interface. With the current standard-WSDL as Web service description language, the interface matching algorithm is proposed from two aspects: name and data type of parameter in Web service message. This algorithm utilizes both clustering techinique and WordNet for parameter name matching. Parameters in service message are classified into concept cluster by utilizing clustering technique. The interface matching algorithm can discover potential message dependency by computing the similarity between service interface, which fulfils automatic and dynamic Web service discovery. Thus the automatic Web service composition is achieved. In the end, the matching algorithm is evaluated on the Textile Resource Planning system by experiments.更多还原
