Theoretical Reflection,Determination and Innovative Application of Subject-Specific Core Publisher in the Digital Intelligence Era
Book acquisition is one of the core functions of a library which determines the quality and development of a library's collection and provides foundation for user services and functional operation.Since the 1990s,the concept of core publishers has been a focus of theoretical research and practice in library book acquisition.Past research revealed significant progress in theoretical development and practical case studies of subject-specific core publishers.However,there are still weaknesses in theoretical depth and practical application.In the era of digital intelligence,it has become an urgent demand to refine conceptual classifications of core publishers to enhance relevance and practicality,ensure a set of unified measurement methods and meet the needs for large-scale and intelligent book selection models.In terms of conceptual refinement,the article proposed to refine the existing general concept of core publishers into three categories according to function:publishing book core publisher,collection book core publisher and citation book core publisher,and defined them separately.It adopted the combination of Bradford's Law and the traversal method for partitioning to address issues related to the unification of core publisher determination methods,automated calculations,strategy optimization,and objective results.It selected the core publishers of Chinese language collections at Xiamen University Library as the subject for determination.A set of indicators including library holdings and borrowing data was chosen to form the indicator system.591 publishers were selected as the subjects for analysis,ultimately resulting in a statistical table of 220 categories of library holdings and borrowing data served as the sample for measurement.Using the entropy method,it was determined that the weight of borrowing book indicators should generally be higher than that of library holdings indicators.It indicated that this approach addresses the difficulties in optimizing the determination of core publishers and identified a well-balanced optimal partitioning strategy based on the distribution density characteristics of publishers across various categories.In terms of application innovation,the article adopted the core publishers as indicators with secondary and tertiary level of the Chinese Library Classification categories,constructing a multi-dimensional and comprehensive data for book acquisition and librarian training,promoting the coordinated development of book acquisition and comprehensive construction of library collections and facilitating the further transformation of book intelligent acquisition from hierarchical analysis model to machine learning model.
