Research On The Scientific Structure And Evolution Of Library And Information Science In The Past Ten Years

In recent years,with the rapid development of information technology and information science,the book information science is changing with each passing day under the new situation.Library information science discipline research team growing,research results is increasing,more and more widely,research scope and application discipline influence is also increasing,the overall display a robust development momentum.The scientific structure of a subject is the most basic content of each subject,and any subject and scholar will be involved.It is worth noting that under the joint efforts of scholars at home and abroad in recent years,there are many about the structure of the scientific research method and visualization tools to stand out,they are all so different,moreover,to some extent,can reflect a subject and a field of scientific structure,convenient for experts and scholars from different Angle of view to understand the subject development,also to the overall development of disciplines and regional development provides a new train of thought and ideas.Based on the 2008-2017 Web of Science as the research object,the core focus of library information Science literature from three perspectives respectively from the themes of the subject,country,compare the situation of change in nearly a decade of internal structure,in order to more clearly reflect the library information Science and other disciplines comprehensively the cross between flow direction of development and knowledge can disentangle disciplines relevant factors of internal logical relationship and the distribution and trends of research output,can more clearly understand the discipline knowledge structure of the internal related topics.This study is divided into six chapters,and the related problems of the multi-perspective scientific structure of library and information science are studied and discussed.The first chapter elaborates the research background and significance,and reviews the research status of scientific structure at home and abroad.It also explains the research content,thinking and innovation of this study.The second chapter,explain the relevant concepts and research methods,the concept of the scientific structure interpretation,this study discipline,national view,theme perspective by using the research methods to explain one by one and instructions.The third chapter,from the Angle of subject,through the construction of citation network between disciplines,respectively analyzing the absorption and diffusion of knowledge.understand the book link relations of information science and other disciplines,in order to probe the scientific structure of macro level.The fourth chapter,from the Angle of the state,through the construction of citation network,using field influence among countries formula of quantitative contribution degree of each country to this discipline of assessing scientific structure of medium level.The fifth chapter,from the Angle of the theme,theme extraction and text categorization by the LDA model,recycled every year in every subject corresponds to the literature to determine the number of heat,so as to reveal nearly 10 years research hot spot and tendency of this discipline,finally through the library intellegence time span of the horizontal and vertical different research perspectives fully grasp the scientific structure of change.The sixth chapter,the conclusion part,elaborates the conclusions from the three perspectives of this study.After summarizing the shortcomings of this study,the difficulties and prospects that need to be overcome in the follow-up study are put forward.
