The problem of knowledge sharing in e-learning has received a lot of attention in recent years. It covers the cross research area including information-integration, and ontologies etc. The paper provides a semantic integration approach to solve the knowledge sharing problem. An ontology based knowledge organization model is firstly built to improve the traditional information resources model, and...
Resource management in distributed and heterogeneous databases is an urgent problem nowadays. In this paper, a framework is proposed to give an efficient method to solve this problem. This framework has two main parts. First, the Web service architecture is given by analyzing many metadata standards and databases. By using Web service technology, the ontology-based framework of is proposed to address...
The paper proposes a concept segmentation method to extract meta-knowledge from the multi-source knowledge base. We improve the traditional structure-based extracting method by using the concept hierarchical partition. The concept and concept relationship can be described with ontology model, which can discover the semantic relationship between concepts. Then a self-learning of meta-knowledge model...
The semantic Web constitutes an environment in which human and machine agents will communicate on a semantic basis. It appears as a promising technology for implementing e-learning. In this paper we have described an approach to bring knowledge service to the semantic web for the area of education and learning. We have shown how knowledge service functionalities can be embedded into semantic Web services,...
