基于知识图谱对自然语言技术在心理学领域应用的可视化分析OACHSSCD

Objective To summarize the application status and characteristics of natural language processing(NLP)technology in the field of psychology by using knowledge graph analysis.Methods CiteSpace 6.1.R2 software was used for visual analysis,with literature from CNKI and Web of Science(WOS)as research samples,and WOS core library was selected.A total of 257 Chinese articles and 285 English articles were selected through keyword retrieval.Results The total amount of domestic and foreign research literature on the application of NLP in the field of psychology showed an increasing trend year by year.Domestic research institutions showed strong independence,different emphasis on their own research direction,and relatively less cooperation between institutions and authors.In contrast,foreign research institutions have formed a more obvious cooperative network relationship.Conclusion Although domestic and foreign studies show a high similarity in the overall research direction,there are differences in specific concerns.Foreign research focuses more on cutting-edge theory and technological innovation,while domestic research tends to mine and analyze the text data in the field of psychology using NLP technology.
