Web服务中消息的异构性使服务发现准确率降低并且它对组装后Web服务流程的运行有很大的影响,对此,提出了一种基于本体的Web服务异构消息匹配及其重用机制,通过概念抽取、合并及匹配组合等方法将已有匹配结果应用到下一次匹配过程中,使得消息自动转换系统在与领域和流程相关的匹配能力上有了明显增强.实验表明,匹配的准确率和召回率平均提高了11.1%和13.2%.
Heterogeneous messages in Web services may not only reduce the accuracy of service discovery, but also interrupt the data flow in composite process. So it is necessary to automatically eliminate those heterogeneities for high-level use such as the process execution. This paper proposes an ontology-based match and reuse mechanism for heterogeneous message types. Compared with existing methods, it improves the capability of discovering the domain-related and process-related mapping by the ontologies extracted from message types and the composition of previous matches. In the authors' experiment, the precision and recall rate increase by 11.1% and 13.2% after the proposed method applied.
