The Study of Secondary Intelligent Organization Methods of CBT Training Library based on Information Entropy

In order to realize the intelligent of computer based training system, this paper puts forward a knowledge form retrieval method based on information entropy. Through analyze the inner link which existing between the knowledge forms, we can build knowledge base, and can find the knowledge forms which cause the failure of training through information entropy calculation. Use information entropy and combination entropy calculation formula, we can retrieval and construction the knowledge chains which cause training failure, and regroup into learners training knowledge base. Overall, this paper puts forward the algorithm of knowledge base secondary organization, this algorithm can automatic ruled out the training knowledge which the leaner has mastered, and we can improve the efficiency of CBT system through the strengthening training.
