The Research Onknovvledge Network And Its Evolution Of The Information Sciencein China

With the development of the Internet,contemporary information science presents multi-dimensional changesboth in interdisciplinary methods and academic background.The trend of research development continues to expand the breadth and depth of the course,which also makes scientific collaborationbehaviorsand research focus in the process of dynamic changes.Digging potential partners and potential cooperative topics of Information Science and exploring of its structure and evolution of the topic helps to quickly capture knowledge network of scientists,hot frontier research and development and scientific research and contributes to decision-makers and managers to provide basis for decision making.Therefore,the study of Information Science Knowledge Network is important.The main contents are as follows:First,this paper reviews the disciplinary structure research status,in order to study the feasibility of visualization methods and necessity of Information Science structure and trends from the perspective of scientific knowledge network analysis.Second,through combing the disciplines and knowledge network content of the information science research,we describe the application of knowledge to study mapping method of the knowledge network.Third,with the application of social network analysis method,information science collaboration network has beenvisualized.The coreacademic cooperation teams,the potential partners and cooperation topics were identified according to the 2-mode heterogeneousmatrix and network.Fourth,the integrated use of TF*IDF and link-comm clusteringalgorithm recognize the topic structure of Information Science.Fifth,social network analysis and 3-mode co-occurrence analysis method is applied to disciplines thematic network analysis,network evolution,which reveals features found in different years with classic and typical topics.Finally,this paper summarizes the whole work and possibilities of the further study.Paper explores the relations between researchers and related topics of information science andidentifies potential partners and potential research topics.Additionally,typical keywords and its revolution reveal the discipline's knowledge structure.These studies reflect,to some extent,revolution and trend of the hot topicsin discipline,which benefits scholarsfrom understanding the development and improvement of information science.
