Contemporary science and technology are changing with each passing day,and the fields of disciplines are numerous and complicated.Knowledge categories are highly differentiated and tend to be integrated at the same time,it is difficult to study a single discipline to meet the needs of society,so multi-disciplinary research is gradually developed.This paper studies the current situation and evolution trend of interdisciplinary intersection of library and information science in China by using LDA topic model,which is mainly divided into the following five steps:(1)Download the title information of 35472 articles in 10 core journals of library and information science in CSSCI database in the past 15 years,and use self-compiled programs to extract the corresponding journal names of these references,and classify them into corresponding disciplines.(2)Form the three-level index of cross-discipline,determine the three disciplines of management,law and medicine as the three cross-disciplines of library and information science,and use the python program to crawl 86075 abstracts of these three disciplines in the past 15 years.(3)Use jieba word segmentation software to segment the abstract,and use Notepad++ to clean the data.(4)Based on the Eclipse integrated development environment,the number of model topics is determined by confusion degree,the research topics of three disciplines in the past 15 years are extracted by LDA,the topic is identified according to the topic-term probability distribution file,the topic intensity of each topic is calculated according to the document-topic probability distribution file,and the subject topics intersecting with domestic library and information science are analyzed in detail.(5)Introduce the time factor,clarify the knowledge information implied in the cross-literature of library and information science and the three disciplines,and analyze the topic evolution situation according to the topic intensity distribution,so as to provide a basis for relevant personnel to carry out scientific research and scientific research topic selection.The research found that the topics of management science,economic society,network security,government functions,patent technology,human capital,and e-government have always been hot topics in the cross-research of library and information science and management.(1)Based on big data and cloud computing technology,build a smart city and smart rural security system to provide a theoretical reference for public service indicators in urban and rural poor areas close to the national average.(2)Optimize the mode of government function transformation based on the Internet +,continue to guide the problem of inconsistency with the public domain in the process of government function transformation,and maximize the use of social resources and high-tech means to scientifically and rationally manage public domain resources.The topics of well-off society,intellectual property,sociology,reform and opening up,think tanks and artificial intelligence have always been hot topics in the cross-research of library and information science and law.The future cross-research points of the two disciplines are as follows:(1)Improve library legislation and strengthen The construction of the legal environment of libraries will more reasonably promote the transformation of library services,enable domestic libraries to integrate with international standards as soon as possible,and ensure the dual rights of libraries and readers.(2)In the era of artificial intelligence,make full use of think tanks to provide reference for government legislative decisions;based on domestic laws,strengthen the construction of public libraries,build a more efficient public library service system,and adhere to innovation,coordination,greenness,openness,The new development concept of sharing will gradually improve the cultural literacy of citizens and promote the establishment of a comprehensive well-off society.The topics of diabetes,depression,AIDS,clinical medicine,sub-health,and hypertension have been hot topics in the cross-research of library and information science and medicine;The future cross-research hotspots of the two disciplines are as follows:(1)Theoretical methods of using library and information science In-depth analysis of medical literature,timely discovery of shortcomings in China's medical research,and take targeted measures to strengthen cooperation between personnel in different regions and improve the efficiency of medical research.(2)Vigorously develop smart medicine,attach importance to the prevention of various diseases,collect patient information and manage it systematically,so that medical equipment,medical staff and patients can communicate and interact more effectively,thereby improving the level of medical treatment.
