Ananlysis Of The Hotspots Of Chinese Library And Information Science(1998-2007)

With the globalization and information time coming,Chinese Library and Information Science(abbreviation LIS)has undergone great changes since 1998. Facing the enormous changes in development of discipline, Chinese academics in LIS are eager to learn systematically, comprehensively, intuitively the development of it in the past decade, such as: what its hotspots are; how its subject structure is; what the trends are; what have effect on Chinese LIS as the popularization of the Internet and electronic resources widely used. And co-occurrence analysis, which quantifies the co-occurrence information of all kinds of information carrier, not only inherits the advantages of qualitative and quantitative analysis, but also overcomes the drawbacks of subjective factors of qualitative analysis. So co-occurrence analysis can excavate profoundly and accurately connotative or potential useful text knowledge; it can dig out the affinity-disaffinity relationship of subject investigated; it can also reveal the structure and changes of subject investigated represented subject or topic. Co-occurrence analysis depending on computer technology becomes important means and tools to support information content analysis for simplicity of its methods and reliability of its results, and its main types are co-word analysis and co-citation analysis. In view of this, this paper tries to use co-word analysis and Author Co-citation Analysis to reveal the main hotspots of Chinese LIS from 1998 to 2007.This paper is divided into the following five sections:The first part discusses the practical value and theoretical significance of the thesis, and summarizes the main research methods and contents.The second part explains the theoretical basis,the type and process of co-occurrence analysis,and introduces the development of co-occurrence analysis at home and abroad. The third part mainly uses the co-word analysis method of co-occurrence analysis to make microscopically empirical analysis on research highlight of Chinese LIS between 1998 and 2007. Five years as a period, it performs cluster analysis, cluster relationship analysis and strategical diagram analysis to the high-frequency keywords of eight core journals of Chinese LIS, and reveals microscopically the research hotspots of Chinese LIS in different period. To sum up, the research hotspots of Chinese LIS is not only a stability there been a change over the past decade, but also is endowed with new features of the times. So the research scope and content of Chinese LIS has a certain characteristics of inheritance, continuity, stability, expansibility, variability.The fourth part mainly uses the author co-citation analysis method of co-occurrence analysis to make empirical analysis by cluster analysis, multidimensional scaling analysis and social network analysis on highly cited authors of eight core journals of Chinese LIS between 1998 and 2007, in order that grasp the structure and research focus of Chinese LIS from a macro point of view. Therefore, it concludes that the hot research realm of Chinese LIS has formed,but the research power is imbalance in hope of further refinement, At the same time, the discipline has have new research fields emerging and achieved gratifying results for the last decade.The last one mainly uses the comparative analysis method, deductive method and inductive method to comprehensively, intuitively and vividly display the trend of Chinese LIS between 1998 and 2007. Meanwhile, the paper also points out the innovations and shortcomings in this research.
