Research On The Subject Evolurion And Cooperative Relationship Of Hotpot Research In The Field Of Information Systems

The field of information systems has been developing at a high speed,and the attention of various research topics is constantly changing,at the same time,emerging research topics are constantly emerging.Summarizing the development trend of information management research is helpful to grasp the development trend of information system,discover the core issues and work priorities in the research process,and provide reference for relevant researchers.Therefore,it is necessary to summarize and analyze this aspect.The main research contents of this paper are:using Latent Dirichlet Allocation(LDA)model,Analyze the study of 8 international top academic journal articles in the field of information systems from 2008 to 2017 to identify the research topics and discover the evolution of the themes and the relationship among the subjects,the authors and the research institutions.In addition,based on the cooperation among the authors of the papers and the cooperation among the authors' institutions,by applying social network analysis methods,this paper builds a network map,and analyzes the close relationship between collaborative researches and the reason behind it with Gephi software.After analyzing the results of LDA modeling and studying the Gephi network map,the main conclusions are as follows:1)According to the evolution trend of attention,it can be roughly divided into ascending type,stable type,declining type and so on;2)There is a leading role in the field of information systems,but its role is limited;3)The cooperation between authors has promoted the development of the information system field,and the cooperation is greatly affected by regional factors;4)There are many small-scale cooperative groups.
