Uncovering the Dynamics of Epistemic Emotions in Asynchronous Online Video Learning: The Long-tail Effects of Like Behavior

With the rapid development of information technology, online learning has become an integral part of modern education. Our study explores the long-tail distribution of learner behaviors in asynchronous learning video forums, focusing on platforms like Bilibili. By integrating Long Tail Theory with sentiment analysis, we propose a three-stage model of cognitive-emotional evolution, revealing content activation and social activation as dual driving factors influencing learner engagement. Our findings provide new insights for optimizing content recommendations and learner interactions in online education.
