Embodiment Construction

[0088] like figure 2 As shown, the present invention comprises the following steps:

[0089] Step 1: Build a social media hashtag generation system. The system such as figure 1 As shown, it consists of an encoding module, a feature fusion module, a topic module and a generation module.

[0090] The encoding module is connected with the feature fusion module and the generation module, and its function is to extract the feature vector of the post, which is composed of a word embedding layer and a sequence encoding layer. The encoding module extracts N in the input post s feature vector of words, the N s The feature vector of each word is aggregated into the feature vector of the entire post, which is referred to as the post feature vector. put N s The feature vector of each word is sent to the generation module, and the feature vector of the entire post is sent to the feature fusion module and the generation module. N s is the total number of words in the post, as a po...

Abstract

The invention discloses a social media theme tag generation method based on themes, and aims to generate theme tags of posts in social media and improve the average precision mean value of the generated theme tags. According to the technical scheme, firstly, a social media theme tag generation system is constructed; preparing a microblog data set for training the social media theme tag generation system to obtain a training set and a verification set; a training set is divided into two steps, in the first step, a multi-cycle gradient descent method is adopted to train a partblock in a generation system, in the second step, the multi-cycle gradient descent method is adopted to train an allblock in the generation system, a verification set is used for verification, and an optimal network weight parameter is obtained. And the trained social media theme tag generation system performs theme tag generation on the post input by the user. By adopting the method, the average precision mean value of the generated tags can be improved, and the generated theme tags are credible and reliable.

Description

technical field [0001] The invention relates to an information processing method in the computer field, in particular to a topic-based method for generating social media hashtags. Background technique [0002] Social media refers to the content generation and exchange platform based on user relationship on the Internet. In the Internet age, social media has become an important channel for individuals to express their opinions and communicate. Users share opinions, insights, experiences and opinions on social media.
