【摘要】：随着互联网上稳定易用的公共Web服务大量涌现，语义Web服务试图以一种相对智能的方式使服务的发现、执行和组合自动完成，语义标注是将Web服务转化为语义Web服务的必要手段，而目前的语义标注方法普遍面临标注质量不理想的问题，因此如何提高Web服务标注质量变得越来越重要。本论文实现一个基于用户交互的Web服务语义增强系统，该系统充分将用户的交互性和用户反馈信息考虑到标注系统中来，文章首先提出一种标注质量评价指标，以此来筛选出自动标注质量不理想的Web服务。其次，分析Web服务标注质量不理想的原因，融合“人”计算的概念，通过引入三种用户交互方式对Web服务标注质量不理想的结果进行修正。最后，通过本体可视化及交互操作对本体进行维护，并提出一种本体扩展算法，用于扩展相应的本体，进而提高Web服务语义标注质量；同时，存储用户交互操作记录，对相同或相似的Web服务标注结果进行自动修改，从而减少用户交互次数。综上，该系统通过引入用户交互，将语义标注与领域本体的扩展相结合，不仅修正了Web服务语义标注质量不理想的结果，而且也扩充并完善了相应的本体，，从而提高Web服务语义标注质量。
[Abstract]:With the emergence of stable and easy-to-use public Web services on the Internet, semantic Web services attempt to automate the discovery, execution and composition of services in a relatively intelligent way. Semantic annotation is a necessary means to transform Web services into semantic Web services. However, the current semantic annotation methods generally face the problem of unsatisfactory annotation quality. Therefore, how to improve the quality of Web services annotation becomes more and more important. In this paper, a Web service semantic enhancement system based on user interaction is implemented. The system takes user interaction and user feedback information into account. In this way, Web services with unsatisfactory quality can be selected. Secondly, the reasons for the unsatisfactory quality of Web services are analyzed, and the concept of "human" computing is fused. Three kinds of user interaction methods are introduced to correct the unsatisfactory quality of Web service annotation. Finally, the ontology is maintained through ontology visualization and interactive operation, and an ontology extension algorithm is proposed to extend the corresponding ontology. Furthermore, the quality of Web service semantic annotation is improved, and the user interaction record is stored, and the same or similar Web service annotation results are automatically modified so as to reduce the number of user interactions. In summary, by introducing user interaction, the system combines semantic annotation with extension of domain ontology, which not only corrects the unsatisfactory quality of Web service semantic annotation, but also extends and perfects the corresponding ontology. In order to improve the quality of Web service semantic annotation.
