The Research Status Of Mobile Learning At Home And Abroad From The Perspective Of Knowledge Graph

With the deepening of informationization at home and abroad and the massive popularity of mobile learning,a large number of scientific research results about mobile learning at home and abroad have been published in the form of papers in various journals.In the face of a large amount of information about mobile learning,how to effectively analyze and evaluate it,and excavate and sort out useful information from it,effectively grasp the research trend of mobile learning at home and abroad,and provide corresponding research development for mobile learning.Theoretical support is provided for the development of mobile learning in China.With the deepening of information technology and the popularization of mobile learning at home and abroad,a large number of research results on mobile learning at home and abroad have been published in various journals in the form of papers.Faced with a huge amount of information about mobile learning,how to effectively analyze and evaluate it,dig out and sort out useful information,and effectively grasp the research situation of mobile learning at home and abroad,so as to provide the corresponding quantitative basis for the research and development of mobile learning,so as to provide theoretical support for the development of mobile learning in China.In this paper,CNKI and Web of Science database are used as data sources.Through the visual comparison and analysis of the literature data retrieved from CNKI and Web of Science,it intuitively displays the situation of publications,journals,researchers' cooperation,research institutions' cooperation,research hotspots and research frontiers in the field of mobile learning at home and abroad.Through a comparative analysis of various aspects of mobile learning at home and abroad,it can learn from the development experience of mobile learning abroad and find the problems existing in the development of knowledge graph in China,and put forward corresponding suggestions for the problems.Determine research focus,judge classic literature,and assist overview for subsequent practice researchers.It provides reference and decision basis for further practice.This paper is divided into five parts.The first part mainly discusses the concept,development,research background and research significance of mobile learning.The second part mainly introduces the research method,analysis process and analysis index selection.The third part mainly uses visual analysis software to conduct in-depth analysis on the publishing situation,literature growth stage,core journals,core authors and core institutions in the field of mobile learning at home and abroad.The fourth part mainly analyzes the research hotspots,evolution of research topics and research frontiers in the field of mobile learning at home and abroad.The fifth part mainly summarizes the research conclusions,suggestions and shortcomings of the paper on the basis of the full study,and looks forward to the future research.It is hoped that through text mining of mobile learning research at home and abroad,valuable information can be drawn.In order to provide useful reference information for researchers,we hope to make a modest contribution to improving the development of mobile learning in China.
