Abstract

The invention provides a user portrait constructing method and device as well as a recommending method and device. The user portrait constructing method comprises the following steps: acquiring a user's characteristic data, and determining the type of the characteristic data; constructing a data portrait according to the characteristic data and the type of the characteristic data; and constructing a user portrait according to the data portrait. The technical scheme of the invention realizes that the user owned personalized information is described by using sentence vectors and article vectors, the insufficiency in portraying the user by text labels is compensated, and implicated information at the semantic level can be expressed, so the portrait has semantic information, and the user is more comprehensively and accurately portrayed.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for constructing user portraits, and also to a recommendation method and device based on user portraits. Background technique [0002] Recommender systems have been widely used in many fields with great success. Among them, personalized recommendation is becoming and will eventually become the mainstream of recommendation system. According to the user's own purchase records, access records and other information, recommend products or information that are more in line with his personal needs and interests, which is called personalized recommendation.
