任务特征对视频用户学习型搜索交互的影响研究
Influence of Task Characteristics on Learning-Oriented Search Interaction of Video Users
摘要
Abstract
This study aims to explore how two task characteristics—task type and task complexity—affect the interaction behaviors and effects of video users in learning-oriented search contexts.Using a comprehensive approach combining experimental methods,questionnaires,and interviews,the research employs bilibili as the test platform.Screen recordings are used to collect search behavior data from 32 participants during the user-search engine results page(U-SERP)interaction stage and the user-content(U-C)interaction stage.The interaction effects of video users'learning-oriented search are evaluated from four dimensions in the user-personal knowledge(U-PK)interaction stage:information encountering,knowledge recording,knowledge comprehension,and knowledge gain.The study finds that task complexity primarily influences users'search interaction behaviors during the U-SERP interaction stage,while task type has a more significant impact during the U-C interaction stage.Additionally,task type exerts a greater influence than task complexity during the U-PK interaction stage.The findings contribute to enhancing the search interaction experience and learning effects of users,and provide insights for optimizing the interaction design and user service functions of video retrieval platforms.关键词
