Research On Construction Of Knowledge Map Of Library And Information Science Based On Ontology

With the application of knowledge management in various fields, in the development of subject research, many scholars begin to pay close attention to the knowledge management.They use knowledge management theory and tools to clear the boundary of subject and analysis the relationship between their subject and other subjects,optimize the retrieval method of subject knowledge,analysis tacit knowledge from explicit knowledge, increasecommunication between different researchers,and share knowledge from other researchers.Knowledge map is an effective knowledge management tool which has been widely used.But the discipline knowledge map traditional mainly adopt keywords and hierarchical directory structure of traditional retrieval methods,the users cannot analysis the knowledge association efficiently,mining the tacit knowledge from explicit knowledge,share knowledge and update knowledge.Based on the above consideration, this paper introduced the ontology technology.Combining the normative with unity advantages of ontology to build a knowledge map of Library and information science.This paper studied the construction of knowledge map of Library and information science based on ontology based on the research results of Ren Ruijuan’team.Firstly,the relevant theories and technologies of knowledge managemnet,knowledge map,and ontology were studied,which was the theoretical basis of knowledge map realization.Secondly,this paper studied the related concepts of ontology,ontology visualization technology and relevant theories of knowledge map and technology,which is the theoretical basis of constructing knowledge map.Thirdly,analyzed the principles,framework and the construction process of knowledge map based on ontology.On the basis of the analysis of keowledge,I began tobuiilt knowledge map of Library and information science based on ontology.Firstly, the knowledge of Library and information science was summarized to determine knowledge nodes in knowledge map,the ontology structure was analyzed,and then began to instantiate ontology,ontology formalization code, then visualize the ontology,finally the knowledge map was evaluated to determine whether to meet the actual needs of knowledge map.In the last part of this paper is mainly to the main work of this paper summary, puts forward the deficiencies.
