摘　　要：OPAC平台检索日志含有图书馆用户潜在的阅读需求,分析和研究用户检索行为是图书馆开展精准化阅读服务、提升创新服务水平的主要依据。杰卡德(Jaccard)系数法具有较强的处理文本数据向量功能,能挖掘文本词汇的内在联系。文章以Jaccard相似系数为基础分析OPAC平台检索数据,从词汇词频和相似关联词汇入手,深入探究馆藏资源与用户需求间的关联,并根据分析结果提出图书馆馆藏资源建设、阅读服务工作的新方向和新路径,从而为用户提供精准化阅读服务。OPAC platform retrieval log shows the potential reading needs of library readers.Analyzing and studying readers'search behavior is the main basis for libraries to carry out targeted reading services and improve the innovative services of the library.Jaccard coefficient method is efficient in processing text data vectors and can explore the internal relationship of text vocabulary.Therefore,based on the Jaccard similarity coefficient,this paper analyzes the retrieval data of OPAC platform,and identifies an innovation path for libraries to construct collection resources and providing reading services accordingly.That is how libraries can provide targeted services for users.

关 键 词：OPAC Jaccard系数 用户检索行为 图书馆 阅读服务
