History,Schools and Trend in Knowledge Map:Investigation and Visualization Based on SSCI and CSSCI
Cao Shu-ji · 2015
As an interdisciplinary research field with rapid development, the history and focuses of knowledge map are of great difference between domestic and foreign academia in different disciplines. This article has done a comprehensive research on important theoretical schools, technological development trails, research focuses, core researchers and organizations by implementing theories and methods of knowledge map.The methods of informetrics analysis are used on the knowledge map related journal articles in Social Science Citation Index( SSCI) and China Social Science Citation Index( CSSCI) from 1998 to 2014,using the tools of SATI、UCINET、Net Draw、Cite Space. Results are shown specifically according to development phases, node articles, highly cited papers, disciplinary distribution, core authors and core journals, high frequency keyword co-ocurrence, author co-citation and keyword network, to reveal the distribution characteristics of time, content and disciplines of knowledge map research and to draw a picture of the development of schools, interdisciplinary study and contributions made by library and information academia by analyzing and computing comprehensive index of core authors, finally to propose the development trend of this field.The main findings of this article are as follows: 1) 2008- 2012 is the period of rapid development and the year 2012 celebrated the most harvest of research achievements and then researches began to decline gradually. We can divide four phases of domestic and international research and the research trail follows a pattern of theory research—implication research—implication expansion of theory and technology—expansion of implication fields. 2) Research focuses of domestic and international academia are alike in combining research of knowledge map with knowledge management, information retrieval and ontology. The two technology and implication research schools are formed internationally while there formed informetrics and implication schools domestically. 3) The research trend includes the weakening and derivation of the knowledge map research, more interdisciplinary research and application research and more cooperation and innovation of knowledge creators.Knowledge map is a fusion of natural science and social science in the multi-disciplinary field of research and application, and because of the incompatibilities of social science and natural science journal citation data at home and abroad, this study is conducted only based on articles in the field of social science journals. The follow-up study should be spread to other subjects to draw more comprehensive results.This article provides new theoretical research angles and data to master the development trail of knowledge map through summarization of its venation, genre and trend. This article also can support the library and information academia to promote creative research and implication of knowledge map, such as research on knowledge organization based on citation analysis, intelligent aggregation of internet information resource of specific fields, construction of classification system and evaluation of internet information resource, and so on.This article has made a comprehensive, integrated, systematical analysis on knowledge map research at home and abroad and investigated time axis, research focus, schools, core researchers and organizations,co-research relationship, and revealed relationship between researchers by computing co-author comprehensive index. 11 figs. 3 tabs. 29 refs.
