Embodiment Construction

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0053] In view of the topic modeling process of UGC content in the related art, since the target object corresponds to multiple features, and there is no correlation between the multiple features, it is impossible to establish a model for the target, which leads to the result of dividing each target object into groups. Inaccurate question.

[0054] In order to solve the above technical problems, an embodiment of the present invention provides an object divisio...

Abstract

The present invention provides an object partitioning method and device based on the object behavior and subject preference. The method comprises the following steps of: acquiring an initial documentset of a first number of target objects; obtaining a topic preference vector of each target object by using a potential Dirichlet distribution model; normalizing a behavior vector of each of the target objects; updating the initial document set with the subject preference vector and the standard behavior vector; calculating a category group to which each target object belongs by using a potentialDirichlet mixing model based on an updated document set of each target object; obtaining an average value of subject preference vectors and an average value of standard behavior vectors of all targetobjects in each category group respectively to obtain a feature vector of each category group. The embodiment of the invention can realize the modeling of a plurality of different characteristics, isconducive to determining the classification of each target object, and improves the object division result.

Description

technical field [0001] The invention relates to the technical field of text data processing, in particular to an object division method and device based on object behavior and theme preference. Background technique [0002] With the development of online social media and e-commerce websites, etc., platforms for generating content based on target audiences (UGC) have become an indispensable part of people's daily life. The development of UGC-based platforms has brought huge business opportunities to enterprises, which can help enterprises discover needs, develop products, and manage customers. [0003] In the process of processing the above-mentioned content in the related art, topic modeling is usually used, and then the topic in the above-mentioned content is discovered by using the topic model, and then each target object is grouped. However, the target object corresponds to multiple features. Since there is no correlation between multiple features, it is impossible to bu...
