Research On Disciplinary Structure And Evolutionary Track Based On Multidimensional Metrology

With the development of the times and the progress of science and technology,The massive influx of information resources being brought in the discipline construction process.The content of many disciplines has been rapidly expanded,and the original disciplinary structures are also changed.How to timely and accurately show the objective existence of the disciplinary structure,and to find that the evolution of academic trace,has gradually become the focus of scholars' research.Through the study of subject structure and evolutionary trace,scholars can track the hotspots and frontiers of a field,find out the factors that affect the integration and fission of disciplines,and grasp the law of discipline development.This paper analyzes the key words,topics,authors and literatures in the core journals of library and information in the past 5 years.The content analysis,co-word analysis,cluster analysis,co-cited and cooperative network analysis and other measurement methods are used.From the micro,medium view to the macro three angles of the subject structure and subject evolution analysis,following conclusions are above:Firstly,discipline evolution does exist life cycle,and influenced by two factors inside and outside,Integration,division,expansion,disappearance,reorganization and a series of evolution will occur.Secondly,from the two aspects of the keyword and the author of the subject structure of the study,we found that the use of key words to study the subject of the subject of the conclusions are more objective,and based on the study of the author to make up for the lack of keyword analysis.Only from the perspective of the literature unit analysis of the academic structure cannot observe the development of the overall discipline of the pulse.Thirdly,only the combination of disciplinary structure and disciplinary evolution can fully reflect the development trend of disciplines.A breakthrough study of the discovery will be able to promote the progress of the other research.The study of any one side is not up to the expected results and objectives of this paper.
