摘要： 合成方案自动转换为BPEL4WS 模块是Web Services 实时动态语义合成系统SASO 的核心组成部分。该文使用DAG 作为Web Services 合成方案的表示方法；在此基础上提出了WTOP 自动转换算法，通过运行时代码动态生成的方法，实现从DAG 到BPEL4WS 的自动转换。

Abstract: Automatically converting Web Services composition plan into BPEL4WS is an essential step in semantic and automatic service orchestration system. This paper employs DAG as an expression of Web Services composition plan, and proposes an automatic conversion algorithm WTOP which automatically converts the DAG into BPEL4WS through dynamic code generation at runtime.
