Study And Design Of Mapping Teaching Intelligent Network Answering System

The designing purpose of surveying and mapping network assistant teaching system is to develop a network teaching platform of surveying and mapping network assistant teaching system as its model. The network teaching platform, as the extending environment and means of the class teaching, should combine with the traditional class teaching. To satisfy the requirements of teaching and learning from both teachers and students, the whole process of the teaching should get supports from the beginning to the end. Evolving network education firstly relies in answering system with the features of convenience and effectiveness as Internet-based Distance Education Support Platform because it can answer the knotty problems from students and eliminates the obstacles on the way of learning. Therefore, answering system is one important of Internet-based Distance Education Support Platform.This thesis analyzes the features of the answering system present in detail, especially its shortcomings, and on the basis of the analysis this paper puts forward the working model of intelligent question answering system. This thesis firstly introduces the basic position of Chinese words segmentation techniques in intelligent question answering system, then analyzes the characteristics of the problems of intelligent question answering system, and finally in light of these characteristics, develop the word segmentation algorithm of intelligent question answering system which is suitable for the professional teaching of surveying and mapping. Based on the words segmentation results, the paper does further researches on the properties of the issues, then does researches into the calculation method of weighted semantic similarity, and puts forth new calculation formula for the problem similarity. In this paper, the application and realization of the calculation methods are studied, including the determination method of words weight in professional fields.
