Research On Context-based Knowledge Support System Of Bank Service For Foreign Students In China

Foreign students learning and practicing Chinese face many difficulties. On one hand, they lack effective Chinese language learning tools in the mobile environment; while on the other hand, the less understandings of China's public service knowledge affect their Chinese language learning effectiveness and efficiency. Especially during their applying and dealing with bank services, they particularly need relevant bank service knowledge support. Towards the real problems for foreign students in China, this paper proposed a context-based knowledge support system of bank service as a solution. The requirement knowledge representation, support knowledge representation and matching method for the above two parts were further studied as the core mechanisms for achieving system functions. The contributions of this paper can be summarized as follows:(1) The context-based knowledge support system of bank service analysis. This paper conducted foreign students' requirement analysis, support knowledge analysis and system function analysis from these three aspects.(2) Knowledge representation model and matching method research. Contexts categorized into Student, Service, Practice and Practice Recovery these four collections, are adopted to describe user's requirements. The user's requirements are represented in XML format as the requirement representation model. Towards the features of bank services and Chinese language practice contents, an OWL ontology and database schema support knowledge representation model was studied. Based on the structure features of the requirement and the support knowledge, a corresponding matching method was constructed.(3) The context-based knowledge support system of bank service design. Towards two main functions of bank service knowledge support and Chinese language practice support, this paper designed system function, system framework, system physical structure and system interaction process.(4) The context-based knowledge support system of bank service realization. Under Client/Server mode, Java Servlet-based server application and Java ME-based mobile application were realized. A system application case was given at the end of this paper.The proposed requirement knowledge representation, support knowledge representation and the requirement-support knowledge matching method studied in this paper indicate new path and direction for the same kind of research problem. The context-based knowledge support system of bank service constructed in the mobile environment can effectively support foreign students to practice Chinese language. It provided complete models, methods and techniques under the practical problem of foreign students'learning and practicing Chinese language.
