Research On The Intelligent Tutoring System Based On The Ontology And The Data Mining Technology

The Intelligent Tutoring System is a kind of digitized study support system in virtue of the artificial intelligence, it can compatibly organizes the teaching resources, implements teaching strategy, provides the teaching service, and carries on the teaching appraisal. The intellectualized degree of the present Intelligent Tutoring System is insufficient, the resources is unable to be used effectively, and it cannot provide the corresponding instruction according to the learners' individuality to realize the individual teaching. We hoped developing an auto-adapted tutoring system to assign study resources, establish individual study path, and change the " impartial treatment " of traditional education according to the cognition level and the style of learners, and then implement the individual education.The research of this article is a crossed study of computer application, artificial intelligence, and educational technique. We have done more thorough research on the educational psychology, data mining and ontology. The main research work as follows, and obtains the certain research results.1. Because of the constructing and implementation of the network study behavior intelligence analysis system based on individual teaching principle, we have accumulated the empirical data that have analysis value, have grasped the cognition level and the study style of each learner. We choose the ID3 algorithm, and make the improvement, then analyze the study model information, form learner study characteristic, and establish the tree classification model of individual study behavior.2. We introduced domain ontology, and constructed the related ontology model of the learners and the study resources in the intelligent tutoring system, simultaneously carried on the semantic description to the study resources, established the study resource distribution library, and then produced individual study navigation way according to the learner's individual characteristic to support the individual study.3. The prototype intelligent tutoring system based on the ontology and the data mining technology has been realized, including the study style analysis and management subsystem, teaching resource management subsystem, teaching resource distribution subsystem. This system provides study resources that adapted to the demands of each learner and enables the full display of study potential in the specific designed environment.The paper finally summarized the research work of this article, and discussed some solution of question as well as the further research work prospect.
