The Design and Development of Question Answering System
Abstract: With the development of information technology, distance education based on the internet will be the main trend of teaching in the future. Question answering system, as an important part on the internet, worked out the communication problem between students and teachers in such a teaching form that people don’t need to face to face. The system adopts the C/S structure and takes the Visual Studio 2005 as development platform, then applies SQL2005 as back-end database and utilizes C# as programming language achieving functions of the user’s registering and logging on, students questioning, management of question answering, management of user’s information and management of question etc. Through debugging, compiling and implementation, the system with simple style interface is fast and convenient to use.
