基于B站弹幕文本的互动式参与文化形成路径研究
A Study on the Formation Path of Interactive Participation Culture Based on Bilibili’s Comment Text

互动媒介生产平台，降低了用户参与网络公共文化的门槛，从而形成一种集消费、生产、传播于一体的互动参与式文化。弹幕评论是考察互动式参与文化形成路径的重要切入口。本研究选取B站三种不同类型且热度较高的视频，通过对弹幕文本进行数据抓取与词频、情感与主题聚类可视化分析，探讨了弹幕主题、情感及视频文本之间的关系。可知不同类型的视频会激发不同的弹幕议题，触发不同的弹幕文本生成机制与参与者身份认同，弹幕评论的文本依赖性和参与感则是形成这种独特互动文化的关键路径。
The interactive media production platform reduces the threshold for users to participate in network public culture, thus forming an interactive participatory culture integrating consumption, production and dissemination. Bullet-screen commentary is an important entry point to study the formation path of interactive participation culture. In this study, three different types of popular videos from bilibili.com were selected, and the relationship between the theme, emotion and video text was discussed through data capture and visual clustering analysis of the bullet screen text, word frequency, emotion and theme. It can be seen that different types of videos will stimulate different bullet-screen issues, trigger different bullet-screen text generator speculation and participant identity, and the text dependency and sense of participation of bullet-screen comments are the key path to form this unique interactive culture.
