Research And Development, Web-based Remote Answering System

With the popularization of the Internet, distance education has developed to web-based education after correspondence courses via post system and courses via TV. As a new educational mode which brings information technology and education together, with new theory which is different from the traditional education and new character which contains numerous" revolutionary factors", web-based distance education injects new vigor into education. As a new thing which hasn't developed fully, however, web-based distance education faces a great deal of problems and difficulties. Question-answer is the key to the teaching-learning activities, but the network's getting involved hinders this two-way exchange between learners and instructors. Thus, research and developing question-answering system, that is, how to giving learners satisfied reply efficiently is the core mission to the development of web-based distance education. The task of this thesis is to put forward a model of web-based question answering system being characterized by its primary intelligence. This thesis has five chapters. The first part introduces the purpose of the research and comparatively analyzes present research status. The second part introduces the web-base distance education system as a whole, describing each module and its function in detail, and 昦lso discussing how to develop this system through analyzing problems and difficulties confronted with and feasible solving methods. The next two parts illustrates in detail automated question answering system which is one of the most important parts of the whole system, including the principles of design, developing project, key technology and realization of the system. The last part compares, analyzes and evaluates the system model and proposes the prediction of the development of the system.
