Abstract: 【Purpose/significance】User interaction behavior in virtual academic community is a hot research content in the field of li⁃brary and information.Through combing and analyzing the research system of user interaction behavior in virtual academic community ,it can provide reference for promoting the research of domestic user interaction behavior of virtual academic community【. Method/pro⁃cess】This paper uses topics and retrieval to obtain relevant literature in CNKI and Wos database,visually analyzes the retrieved litera⁃ture through hot keyword statistics,and summarizes it into five hot research topics:mechanism model,characteristics,influencing factors,effect evaluation and reverse behavior of user interaction behavior【. Result/conclusion】On the basis of clarifying the current academic research context,this paper puts forward a forward-looking direction of user interaction behavior in virtual academic community,that is,
continue to deepen the data mining of user conversation interaction behavior; explore the mechanism of reverse behavior and logical behavior beyond the value center; build a knowledge screening system in the process of obtaining information【. Innovation/limitation】Summarize the basic theory and practical application of user interaction behavior research in virtual academic community at home and abroad,and put forward suggestions to promote the development of this field in view of the shortcomings of existing research.
