Information retrieval personalized recommendation service research method based on reader interests and preferences

Abstract

The invention belongs to the field of book management, and particularly relates to an information retrieval personalized recommendation service research method based on reader interests and preferences, which comprises the steps of analyzing a user interest and preference model technology, and classifying and summarizing an information collection mode, a user interest description mode and a project description mode in the interest and preference modeling technology; analyzing a solution of an existing personalized recommendation technology on a user interest change problem, and proposing an improved interest model; analyzing implementation processes, application fields and respective advantages and disadvantages of the at least three book personalized recommendation systems; an improved book personalized recommendation model is provided by analyzing and comparing a book personalized recommendation technology and combining the characteristics of a reader interest and preference model ina personalized book information service technology. Through comparison and analysis of several personalized recommendation technologies, a research method for information retrieval personalized recommendation service based on reader interest and preference is constructed, so that the utilization rate of library information resources is expected to be improved.

Description

Technical field: [0001] The invention belongs to the field of book management, and in particular relates to a research method for information retrieval personalized recommendation service based on readers' interest preferences.
