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.

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。
