| 摘 要： | 提出一种基于概念格的图书协同推荐方法。首先建立用户与图书之间的概念格,然后根据概念格中图书节点之间的继承关系,从下向上回溯用户之间的共同偏好,快速计算用户之间的相似度,以确定目标用户的"最近邻居"。最后通过计算协同推荐值,实现对目标用户推荐其可能感兴趣的图书,从而为图书的协同推荐提供支持。

| Abstract: | The method of effectively recommending users books based on concept lattice is proposed in the process of collaborative recommendation of digital library. Firstly, the concept lattice of customers and books is built. Secondly, according to the inheritance relationship of nodes in concept lattice, the similarity degrees between users can be calculated by searching the common preference between users, and then "nearest neighbors" of the target user can be confirmed. Finally, recommending books can be realized by calculating the collaborative recommendation value. |
