互动视频是一种以一定的故事逻辑组织而成、支持用户通过点击互动选项跳转至不同的视频片段的新型视频模式。这一视频类型在互联网中吸引了大量用户的参与，以哔哩哔哩弹幕网为主，许多用户主动选择观看互动视频。从满足用户需求的角度，以“使用与满足”为理论基础，互动视频产生了何种传播效果是值得关注的一个问题。本研究采用了定量和定性相结合的研究方法，使用了文本分析法和LDA主题分析相结合的研究方法，对五个互动视频的6789条评论进行了分析。这五个视频分别具有代表性的特征，分别为：知识类互动视频、游戏类互动视频、基于影视IP的剧情类互动视频、无IP支持的剧情类互动视频、测试类互动视频。依照“使用与满足”理论中五个需求的框架对评论进行编码后，文章对五个视频中对应各类需求的评论占比进行描述性统计。随后，文章以五类需求作为分类，对评论进行了LDA主题分析，并使用gephi进行可视化呈现。研究发现，互动视频满足用户需求的效果会因互动视频类型的差异而有所不同。大部分的视频以满足用户的情感需求为主，而互动视频对于用户压力释放需求的满足程度较低。用户五类需求的网络节点都紧密围绕着视频的主题，互动视频的互动形式使其本身的内容满足了用户的各类需求。

Interactive video is a new type of video format which is organized with a story line and supports users to jump to different segments by clicking interactive options. This type of video has attracted a large number of users on the Internet, mainly on video platforms like Bilibili in China. Many users actively choose to watch interactive videos. From the perspective of satisfying users’ needs, it is noteworthy to explore the communication effects generated by interactive videos basing on the "uses and gratifications" theory. This study adopted a combination of quantitative and qualitative research methods, using text analysis and LDA topic analysis. 6789 comments in five interactive videos were analyzed. These five videos have representative characteristics, containing knowledge-based interactive videos, game-based interactive videos, plot-based interactive videos adapted from film and television IPs, plot-based interactive videos without IP support, and psychological test-based interactive videos. After coding the comments according to the five-demand framework in the "uses and gratifications" theory, the article conducted descriptive statistics on the proportion of comments corresponding to various needs in the five videos. Subsequently, this article used LDA analysis to analyze the comments corresponding to the five types of needs and visualized them using Gephi. This study found that the effect of interactive videos on satisfying needs varies depending on the type of interactive videos. Most videos mainly satisfy users' emotional needs, while interactive videos satisfy users' needs for stress relief to a least extent. The network nodes of users' five types of needs are closely centered around the theme of the videos. It is obvious that the interactive form of interactive videos prompts their content to satisfy various user needs.
