摘要: 为了实现组合相关处理的自动化和智能化,提出一种基于语义的Web服务自动组合算法。该算法采用深度优先的方法计算概念间的语义相似度,基于前驱服务生成从请求输入到请求输出的服务组合方案。实验结果表明该算法充分利用Web服务功能的语义信息,与已有算法相比,简化了自动组合过程。

关键词: 语义距离, 语义相似度, 前驱服务

Abstract: To realize the automation and intelligence of relative treatment for compositon, this paper proposes a Web service automatic composition algorithm based on semantics. It adopts depth first method to compute the semantic similarity among concepts, generates the service composition scheme from request-input to request-output based on the pre-services. Experimental results show that the algorithm fully imposes semantic information of Web services, compared with existing algorithm, it simplifies the course of automatic combination.

Key words: semantic distance, semantic similarity degree, pre-service
