摘　　要：目前数字图书馆书目查询受到海量数据影响,导致查询查全率和查准率均较低,针对上述问题,设计了基于关联规则的数字图书馆书目查询系统。设计书目分类导航模块,读者通过超链接向书目数据库传输查询申请;使用数字图书馆数目查询接口,监控系统中索引数据的变化,并利用Apache服务器能够动态加载服务器进程空间。根据关联规则构建查询索引,以该索引为依据,设计数字图书馆书目查询步骤。由系统测试结果可知,该系统查全率和查准率最高值均为0.78,具有高效的查询效率。At present,the bibliographic inquiry of digital library is affected by massive data,which leads to the low recall rate and precision rate of inquiry.The navigation module of bibliographic classification is designed.The reader can transfer query application to bibliography database through hyperlink.Using the digital library number query interface,monitoring the changes of index data in the system,and using Apache server can dynamically load server process space.According to the association rules,the query index is constructed,and the steps of digital library bibliographic inquiry are designed.According to the system testing results,the highest recall and precision values of the system are 0.78,indicating efficient query efficiency.
