Study on the construction of digital library model under semantic Grid environment

This paper proposes a semantic grid structure of digital library under semantic grid environment by combining the research results of grid computing with the research o f the digital resource´s semantic cooperation in digital library, and discusses the key technologies and services of digital library knowledge organization under semantic grid environment. Then not only discusses semantic notes and knowledge discovery on the basis of ontology, but also the model conversion tacit knowledge based on ontology. On this basis, it describes the ideas about the structural model under the semantic grid environment. Lastly it analyzes this modal from Knowledge acquisition layer and knowledge organization layer and knowledge grid service and application layer.
