Abstract:

This paper provides a comprehensive and intuitive overview of the progress and evolution of library technology application research in China, based on an analysis of CSSCI-indexed papers from CNKI published between 1998 and 2024. The study employs Sentence-BERT and Dynamic Topic Models (DTM) to extract semantic and thematic features from the texts. Utilizing the K-means algorithm for topic clustering, it examines thematic evolution from a macro perspective. A co-occurrence network of key terms is subsequently constructed to analyze focal points at different stages from a micro perspective. The findings reveal that library technology application research in China centers on nine major themes, and identify five distinct phases of development. The study highlights the substantial influence of emerging technologies in driving advancements in the field. The research closely tracks technological developments, actively investigating new applications of these technologies in libraries, with the aim of enhancing efficiency, intelligence, and personalized services.
