The Ontology Of Mobile User Information Behavior Research In China Based On Co-word Analysis

In the end of 20 th Century,the Chinese academic society began the research of user management and service based on network,and the research of user information behavior was highly valued by both theory and application.During in 21 th Century,with the arrival of mobile Internet,the environment of information utilization gradually migrates from the traditional Internet to the mobile Internet.The research of user information behavior in the mobile Internet has become a branch of information user subject,which has produced a large number of achievements till now and has a great of characteristics of the growth period.How the future mobile user information behavior research is going to mature,how the theory and method system will be deepened,what kind of position in modern user management and service,and so on,the answer to these questions needs scientific and rational basis,so it is necessary to sum up the existing results with systematical,comprehensive and scientific research.On the platform of CNKI,This paper retrieval literature about mobile user information behavior published during in 2007 to 2016,download the bibliography and obtain the high-frequency key words,after the building of high frequency co-word matrix,we uses co-word analysis tools to sum up the hot topics in the field.On this basis,we construct the ontology of mobile user information behavior and predict its future development trend based on ontology visualization analysis.This paper,consisting of five parts,performs the investigation and analysis by literature research,co-word analysis,ontology construction and other methods.Firstly,illustrating the main points of mobile user information behavior at home and abroad,and expounding the research background,research contents,research methods and innovation points of this paper.Then we introduce the concept and operation process of co-word analysis and ontology construction.Secondly,expounding the process of obtaining the research data,discriminating the extraction method of the high frequency keyword threshold,and completing the extraction of high frequency keyword table and the construction of high frequency co-word matrix.Thirdly,UsingSPSS as a co-word analysis tool,carrying out factor analysis,cluster analysis and multi-dimensional analysis based on high frequency co-word matrix of mobile user information behavior and summarizing the hot topics in the research of mobile users information behavior in China.Next,based on the research hotspot of mobile user information behavior in China,designing the ontology of mobile user information behavior with introduction of authors,subjects,years and the other related elements,and construct the ontology by Protégé.In the last,we output the visual atlas of the ontology.Analyzing the specific research situation from hot topics,core authors,core subjects,core year and so on,and predicting the future development trend of this field.
