Research On Subject Services Of University Libraries Based On User Portrait

With the continuous development of the information society,the social environment is changing and the users’ needs are constantly updated,the traditional service mode of college libraries,which is mainly based on documentary information service,must be reformed to meet the social development.Subject service is one of the important initiatives for change and innovation of university libraries,which can make the combination of university library collection resources,human resources and equipment resources with users’ needs,so that resources can be fully utilized and users’ needs can be satisfied.In this paper,in order to improve the quality of subject services,we construct user portraits based on user data,analyze the problems of subject services in college libraries,and accordingly give optimization strategies for subject development in college libraries.Based on this,the article mainly discusses from three aspects.The first part compares and analyzes the research status of user portrait and discipline service at home and abroad,explains the related concepts,and then explains the use and satisfaction theory,Laswell’s 5W communication model and other related theories used in this paper,and sorts out the content of discipline service.In the second part,a questionnaire was designed based on relevant studies and web research,and questionnaires were distributed to different types of universities in China for investigation.Based on the valid data collected from the questionnaires,statistical analysis was conducted using SPSS software,K-mean algorithm,and six types of user profiles were clustered,namely,learning support,teaching support,research support,preference indifference,information literacy,and usage loyalty,and five issues were summarized based on descriptive analysis and clustering results as well as correlation analysis,namely,subject construction,content construction,media construction,object construction,and evaluation construction.In the third part,based on the five problems presented in the preliminary survey of subject services,the strategies for optimizing the development of subject services in university libraries are proposed in terms of user needs,resource construction,subject service content and mode construction,subject librarian team construction and evaluation system construction by using the theoretical basis of use and satisfaction theory and combining with the characteristics of current development of subject services in university libraries and user needs.
