This paper mainly introduces the ontology building, put forward a calculating method of semantic similarity based on ontology, and apply it to build user interest model, learning resource model and personalized recommendation model. Based on the above work, we build a personalized learning system based on ontology. Finally the validity of the model were verified by contrast experiment.
"HowNet"[1] is a commonsense knowledge database. The description object of "HowNet" is the concept represented by Chinese and English words. It is used to reveal the relationship between the concepts and the relationship between attributes of concepts. It has a rich of lexical semantic knowledge and world knowledge, and those knowledge is the basic resource of Chinese information...
Based on learners' personalization features, the personalized learning system can actively recommend learning contents for learners to learn, which fully reflects the thought and idea of modern education. Nowadays, it has become one of the hot research topics in the domain of learning system development. This paper constructs vector space model for learning resources in knowledge base and also constructs...
In this paper, the representation method of user interest model is a combination of vector space model with Ontology. It introduces the algorithm of semantic similarity when calculating the term weight, and considers the semantic similarity of words, and then the term weight is updated through the Bayesian network. This paper focuses on the steps of building and updating the user interest model, and...
The constructing and updating of user interest model, determines the accuracy of the user information representation, and directly influences the service quality for the users. This paper will show you by introducing some browsing action data into user interest model updating strategy, carrying on the experiment by using the designed system, and obtaining the reasonable values of browsing behavior...
Data structure is the specialized core course for students majoring in computer science and technology, which has considerable difficulty not only in learning but also in teaching. Project-based learning (PBL) model is an important means for learning, it had been introduced to the curriculum in the past few years. We conducted project-based learning research and practice making full use of network...
