The emergence of digital humanities has a profound impact on the research process and content of the humanities,and it is naturally connected to the library whose main function is knowledge organization. The purpose of this paper is to examine the relationship between Library Science and digital humanities,to seek the integration of development paths,and to broaden the research field of Library Science through the statistical analysis and data mining on the digital humanities.

    The paper sets Web of Science core data as the data sources,including SCI-E(1965-2015),SSCI(1965-2015)and A & HCI(1975-2015),and chooses article for document type. In order to fully reflect the general picture of the field of digital humanities,we obtain basic data set by using the key words “humanities digital” and “computing humanity”. Then we select digital history,computational linguistics,digital art,digital archaeology as search terms to mine in the field；we select computational turn,GIS,text mining and visualization,virtual reality,social media as search terms in order to reveal the text mining and visualization technology in the humanities；we select E-research,digital scholarly as search terms to explore humanities research practice and academic culture under the drive of the digital humanities. We finally obtain 958 related articles as data analysis set. Using SATI3.2,CiteSpaceIII tool,the paper carries out the quantitative statistics and qualitative analysis on those papers.

    The study shows that computational linguistics,the construction of large-scale databases and electronic text have contributed to the birth of humanities computing,which becomes a cross research field of computer science and the humanities. Along with the development of digital humanities research,its connotation becomes more compatible and emphasizes computational turn,and considers the the reconstruction of the context and content of humanistic knowledge,so as to construct the contemporary knowledge system and cognitive style. The evolutionary path of the digital humanities research shows that the theory,method,and practice of Library Science and digital humanities research have the trend of synergetic development. From the perspective of technology application and data foundation,Library Science is the basic subject of digital humanities,and it will be one of the main applications of digital humanities achievements.

    The hot topics of digital humanities research are as follows:the basic theoretical questions of the digital humanities,the turning of academic practice in humanities under the drive of technologies,the change of academic culture in humanities caused by a new mode of cooperation and the construction of the infrastructure for the study of digital humanities. Comparative analysis shows Library Science is a basic subject of digital humanities. The practice and research of the digital humanities cannot be separated from the database and electronic text which are closely related to the library,even some of the digital libraries are regarded as digital humanities projects. On the essence of discipline,both Library Science and digital humanities originated in the practice,some of them coming from the practice of information services. In the field of practice,the library and the digital humanities are both concerned with the research and practice of the recorded information and text.

    Finally,the paper puts forward that the libraries in China need a much broader perspective to study library and digital humanities,create a friendly digital humanities environment,and establish an effective organization and management and so on,to explore digital humanities theory and practice. 10 figs. 1 tab. 54 refs.
