Abstract

The invention relates to a movie user portrait construction method, which comprises the following steps of 1, selecting users who have published Chinese movie comments in a movie community website, and collecting static data and dynamic data of the users; 2, constructing a three-layer label system of a movie user portrait according to the obtained multi-dimensional data of the sample movie user; 3, according to the corresponding relation between the multi-dimensional data of the movie users and the labels in the label system, the first-layer labels and the second-layer labels of the movie users are predicted from bottom to top according to the label hierarchy, and a perfect single-user portrait model is constructed; and step 4, carrying out movie preference analysis on the group movie users with a certain type of common characteristics, generating a third-layer label of the movie user portrait, and constructing the group user portrait. According to the invention, the original data of the user is analyzed and mapped to generate the label system, so that the attribute labeling of the movie user and the construction of the group user portrait model of the crowd with the same attributeare realized.

Description

technical field [0001] The invention relates to a method for constructing movie user portraits, and belongs to the fields of big data, data mining, natural language processing, and machine learning. Background technique [0002] In the context of big data and social media, Internet platforms analyze user information and potential user preferences in behavior, and carry out personalized promotion of platform information. User portrait, that is, labeling of user information, is a target user model based on a series of real data. User portraits can use "labeling" to mark users' social attributes, living habits, and consumption behaviors. As a main part of the recommendation system, user portraits are widely used in business fields such as e-commerce product recommendation and advertiser advertisement placement by mining user personality characteristics, individual differences between users, and platform user group characteristics. With the outline of user portraits, the platf...
