Question Answering Using Web Services: A Case Study in Tourism Packaging

Abstract

While Web Question Answering System WQAS) has made a great progress in the Internet currently, a major limitation is that the information sources current WQASs are using is limited to static page texts. Much users-interested content information is provided to the web dynamically through programs. Web services are becoming the dominant forms of such sorts of programs. In this paper, we propose a novel WQAS architecture that uses Web Services as the information sources. The system adopts a semantic web for content modeling, logic grammar for question parsing, and Hierarchical Task Network HTN) for user query problem solving. A case study in E-Tourism domain is investigated, which implements dynamic packaging for tourism products.
