Abstract

The invention discloses a university library-oriented books personalized recommendation method, and solves the problems of poor large-scale data storage and query, extendibility and recommendation effect in an existing books recommendation algorithm of a university library. According to the basic thought, the method comprises the following steps of firstly, building a graph model by taking readers, books and the like in the library as nodes; secondly, converting operation log files of the readers into a reader-books category preference matrix, calculating similarity between the readers by the reader-books category preference matrix and a reader personal information matrix, and establishing an associated graph spectrum by taking operations and mined information as edges; thirdly, by combining the associated graph spectrum with spectral clustering, proposing a new books personalized recommendation model, and performing calculation to obtain class cluster distribution about the readers; and finally, when books recommendation needs to be carried out, calculating a recommended books list according to a collaborative filtering algorithm in a class cluster corresponding to a reader.

Description

technical field [0001] The invention belongs to the technical field of machine learning, and more specifically relates to a method and system for personalized recommendation of books oriented to university libraries. Background technique [0002] In the daily study and life of various colleges and universities, libraries play an important role both among students and among teachers. Students and teachers cannot do without the help of libraries to find documents or learning materials. However, with the explosive growth of modern information, the number of books in university libraries has exceeded one million. Although modern technologies such as digital libraries have alleviated this problem to a certain extent, readers still need to search through keywords. Browsing and screening among many search results, and in many cases, readers do not know what their target books are. Facing such problems, the personalized book recommendation system was born. [0003] The current rese...
