摘　　要：针对图书馆书目推荐系统忽略用户需求的缺陷,研究基于计算机网络技术的图书馆书目推荐系统设计。用户通过用户模块的用户展示界面登录系统,书目推荐模块接收用户登录信息后由数据挖掘引擎启动协同过滤模块,通过基于协同过滤的书目推荐算法充分挖掘计算机网络内图书信息,使用各图书关键词权重计算图书、用户、图书与用户间相似度,依据相似度利用匹配树原则对图书生成匹配规则,符合最小支持度以及最小置信度的图书建立推荐书目,并将推荐结果通过用户展示界面展示给用户。系统测试结果表明,采用该系统可充分考虑用户需求,为用户推荐所需书目,且推荐书目的召回率、覆盖率、准确度、新颖度均处于理想范围内,具有较高的实用性。In view of the defect that the existing library bibliographic recommendation systems ignore the needs of users,a library bibliographic recommendation system based on computer network is designed. The user logs in the system by the user display interface of the user module. In the bibliographic recommendation module,the data mining engine is used to start the collaborative filtering module after receiving the user′ s login information. The book information in the computer network is fully mined by the collaborative filtering based bibliographic recommendation algorithm. The keyword weights of each book are used to calculate the similarities between books,the similarities between users,and the similarities between books and users. On the basis of the similarity,the matching tree principles are used to generate matching rules for books. The books that meet the minimum support and the minimum confidence are used to establish a recommended bibliography,and the recommended results are showed to users by user display interface. The system test results show that the designed system can fully consider the needs of users and recommend the required bibliographies for users,and the recall rate,coverage,accuracy and novelty of the recommended bibliographies are within the ideal range. Therefore,the system has high practicability.
