Abstract

The invention provides a single-classification collaborative filtering method based on a user personality hierarchical structure, and relates to the field of computer data processing. The method for applying the user personality hierarchical structure to the single-classification collaborative filtering algorithm provided by the invention is suitable for processing implicit feedback data. A traditional single-classification collaborative filtering method does not have a hierarchical structure fused with a user; according to the method provided by the invention, based on weighted matrix decomposition, users are layered by introducing personality trait information, a layered structure of the users is constructed, existing information is fully utilized, the problem of data sparseness is relieved, and the unfriendliness of a recommendation system to new users is reduced, so that personalized recommendation of commodities to the users is more accurate.

Description

technical field [0001] The invention relates to the technical field of computer data processing, in particular to a single-category collaborative filtering method based on user personality hierarchical structure. Background technique [0002] With the development of e-commerce, the products on major shopping websites are extremely rich, and how to help users easily select favorite items from a variety of products has become a major challenge. In this environment, the recommendation system has gradually become one of the tools to deal with this challenge, and has been applied to major e-commerce shopping sites and video music sites, increasing the two-way economic benefits and overall satisfaction of consumers and businesses. [0003] Collaborative filtering method is one of the most popular product recommendation methods, which can predict the user's preference for items only by the user's historical browsing data or scoring data. However, in shopping and music video websit...
