基于BERTopic模型的用户层次化需求及动机分析
User Hierarchical Need and Motivation Analysis ased on BERTopic Model:Taking Douyin Platform as an Example
摘要
Abstract
[Research purpose]This study aims to analyze the composition of user-generated content on the short video platform,extract its structure and evolution rules under the influence of time evolution and social events,tap the internal behavioral needs of short video us-ers,and explore its potential motivating factors for user participation behavior.[Research method]Taking 2.37 million short video re-lease data on the Douyin platform as research sample,this research uses the BERTopic model to implement topic clustering,summarizes users'attention to topics within a certain period of time,and introduces Maslow's Hierarchy of Needs theory to reveal the needs and moti-vations behind user participation behaviors in the context of the Internet.[Research conclusion]Firstly,in terms of the hierarchy of needs,users have varying levels of attention to different levels of hierarchical needs,and this level of attention ranges from high to low as follows:esteem needs,safety needs,love and belonging needs,self-actualization needs,and physiological needs.And their order can re-main stable over time.Secondly,users show a higher level of engagement in social events,and these events can significantly affect the content of users'video releases.However,it has a minor impact on the distribution of users'attention at different levels of needs.Finally,there are differences between the users'focus in interacting with videos and posting videos.When publishing videos,users are more con-cerned about meeting esteem needs,while during interactions,the focus on self-actualization needs significantly increases.关键词
