基于方法聚类的Web服务检索技术

Web Service retrieval based on operation clustering

充分利用Web服务的描述信息,提出基于方法层的Web服务建模方法。在给出服务方法互相关性定义及其度量方法的基础上,提出了一种基于k-means的服务聚类算法产生方法概念,利用这些方法概念,给出了基于方法层的服务检索模型及其相关算法。实验结果表明,所提出的Web服务检索方法具有良好的检索效果。

By taking full advantage of the service description information, an approach for modeling Web services at the operation level was proposed. Base on the definition of service co-relevance and its measuring approach, a Variant k-means clustering method has been developed to group service operations into different operation concepts. A service retrieving model and the corresponding algorithms have also been devised using the operation concepts. Experimental results show that the proposed approach greatly improves the performance of retrieving Web services.
