摘要
对我国图书馆人才队伍建设与管理领域进行文本挖掘,揭示该领域研究热点主题。选取中国知网(CNKI)相关文献摘要作为研究语料,运用Python的gensim库构建LDA主题模型,进行文本挖掘,利用困惑度和一致性确定最佳主题数量、计算各主题强度。最终确定10个热点主题数量,其中高校图书馆员培养、图书馆建设与阅读推广、公共图书馆服务、多角度合作、用户需求与满意度这五个主题的主题强度较高,揭示了主题演化趋势。
s from related literature on CNKI(China National Knowledge Infrastructure)were selected as the corpus for this study.The LDA topic model was constructed using the Gensim library in Python to perform text mining.The optimal number of topics was determined based on perplexity and coherence measures,and the strength of each topic was calculated.Ten hot topics are identified,with the cultivation of college librarians,library construction and reading promotion,public library services,multi-angle cooperation,and user needs and satisfaction being the topics with higher strength,reveal trends in topic evolution.
