Design And Realization Of Intelligent Q/A System's Based On Knowledge Tree

As the rapid development of Internet and social informationization , the dissemination and generation of knowledge had a rapid growth. Although the traditional way of classroom education and face-to-face Q/A still hold main status , it is incapable of meeting the people's demand for lifelong education,consolidating the knowledge and dealing with difficulties. In this context, distant education and various Q/A system generated. As an important auxiliary tool of active learning and examination of learning situation, intelligent Q/A system try to invent an actual and face-to-face Q/A environment.It is a beneficial supplement of the traditional education for it reflects constructivism and makes students to experience classroom instruction personally education.With the development of data mining's application in many fields, people devoted in seeking new direction and space in recent years.The article that aimed at solving problems and using successful experience of advanced intelligent Q/A system overseas applied the data mining algorithm to the intelligent Q/A system, proposed and realized the Q/A design proposal based on the knowledge tree's, and aimed at solving problems and using successful experience of advanced intelligent Q/A system. We also used intellectualized technology in aspects such as question pattern matching and knowledge database design. At the same time, we solved the difficulties in inputting formula in web page and making the system advanced and superior.It is said that a good education software is not only necessarily to highlight its technical characteristics, but also need to integrate our thinking of education. The teaching and learning ideologies in the intelligent Q/A system specially the social constructivism are important to us for student-centered, teacher-led double main teaching.A period of on-line practice proved that recall of intelligent search and accuracy of the intelligent Q/A system is quick and accurate.This system had intelligence as well as self-renewal.And this system also had user-friendly merits such as formula input and prompt feedback.Completion of this research projects is not only good for the educators to understand blending learning and teaching based on intelligent Q/A system, but also important for extensive development of intelligent Q/A system and other education software. Finally, let our educator pay attending to long-distance teaching and auxiliary study by network,and carry on more thorough theory and the practice exploration in this field.
