中文摘要：

[目的／意义]挖掘图书馆借阅数据，从网络属性、节点重要性和社团模块来研究各学科书籍之间的关系，有助于指导图书资源管理、读者服务和学科建设工作。[方法／过程]基于复杂网络的理论和方法对图书馆学生借阅数据进行分析，以各类目书籍为节点，构建图书共现网络。在此基础上，对加权网络的网络属性和节点重要性进行探讨，并通过随机游走算法划分书籍社团。[结果／结论]研究揭示了书籍及学科间的内在联系，同时，也为加权网络的实证研究提供一定的经验材料。

英文摘要：

[Purpose/significance] Mining library book-borrowing data and analyzing relationships among books of different subjects from the perspectives of the network attributes, the importance of nodes and community modules will con- tribute to guiding book resources management, library services and subject construction. [Method/process] In order to analyze the book-borrowing data of students, this paper built a co-book network whose nodes were the books of different subjects, based on the theory and methods of the complex network. On this basis, the network attributes and the impor- tance of nodes were analyzed in a weighted network. The books were divided into different communities by Walktrap. [Result/conclusion] This research reveals the inner relationships of books, and also provides some empirical materials for empirical research of a weighted network.
