Research On Course Information Integration Technology Towards Internet

The popularity of the Internet makes the amount of information on the Internet increased dramatically,because of the attributes of the Internet information,which include dispersion,complexity,it is obviously very difficult to find the needed information in such a large Internet ocean.For example,for students and teachers in schools,they all need some high quality exercises resources to improve their own learning and teaching level,because these learning resources scattered as different forms in different places on the Internet,how to effectively use these resources has become a problem to be solved.This paper makes a research on this problem,and puts forward the framework and solving strategies of course exercises information integration towards Internet,the main works are as follows:(1)Put forward a conceptual model of Web information integration for college curriculum exercises.The concepts of curriculum and exercises are defined.For different types of exercises,a formal description method based on regular expressions is proposed.(2)Put forward the information integration and fusion strategy for college curriculum.The appropriate data sources are determined by comprehensive evaluation of different data sources.This paper puts forward the method of identifying and extracting exercise information based on Web snapshot,including the identification of exercise types,the fusion of different data source exercises information,the information supplement of incomplete exercises based on Web.(3)Put forward the evaluation strategy of curriculum exercises,based on AHP analytic hierarchy process and BP neural network.On the basis of comprehensive analysis of a large number of exercise samples,four factors affecting the evaluation of exercise quality are determined.The factor of exercises difficulty is obtained by the neural network algorithm.Finally,the weight proportion relation between the influence factor and the exercise quality system is obtained through the AHP analytic hierarchy process and then achieve our goal of evaluating exercises.(4)Based Web exercise information integration and fusion,this paper design and implement a system based on the model and method proposed.Based on a given course name,the system can automatically find and integrate the related Internet exercises information.The system has some innovation,we have not seen similar system at present.
