文字刺激触发的信息偶遇——基于社交问答平台的日记研究

Information Encountering Triggered by Textual Stimuli:A Diary Study Based on Social Q&A Platform

[目的/意义]以知乎为代表的社交问答平台是有利于信息偶遇发生的信息环境,研究这一特定环境中的信息偶遇过程,特别是以用户提问形式存在的文字刺激对信息偶遇的触发机制,将进一步丰富信息偶遇的理论基础并对社交问答平台的设计提供优化启示。[方法/过程]以知乎平台为研究背景,采取基于关键事件技术的日记法采集了181个有效的信息偶遇事件,采用定量和定性相结合的方式,对偶遇提问的内外在特征、偶遇过程中用户与提问相关信息的交互、以及用户与提问相关信息的交互强度和提问特征间的关系进行分析。[结果/结论]长度较短、可理解性和新颖性较高的提问更容易被用户偶遇;在偶遇过程中,用户倾向于在注意到提问后先检查问答帖的文字、图片和视频内容,随后采取一系列捕获行为;用户与信息的交互强度与提问的外在特征没有显著关系,在内在特征上,提问的新颖性越高,人们对其的趋近程度越强。

[Purpose/Significance] Social Q&A platform represented by Zhihu is an information environment conducive to information encountering(IE). Studying the IE process in this specific environment, particularly the trigger mechanism of textual stimuli in the form of user questions, will help enrich the theoretical foundations of IE and provide optimization strategies for the design of social Q&A platform. [Method/Process] A diary study of IE was conducted in the context of Zhihu services. A total of 181 valid IE incidents triggered by textual stimuli on Zhihu were collected. With an online questionnaire created based on the critical incidental technique(CIT), we analyzed the internal and external characteristics of the encountered questions, the interaction between users and questions related information, and the relationship between characteristics of textual stimuli and users’ interactions with the encountered questions both quantitatively and qualitatively. [Results/Conclusions] Questions with shorter length, higher comprehensibility and novelty were more likely to be encountered by users. In the IE process, users tended to examine the text, pictures and video of the Q&A post after paying attention to the question, and then take a series of actions to capture the information. The interaction intensity between users and information had no significant relationship with the external characteristics of questions. In terms of internal characteristics, the higher the novelty of a question is, the more likely users are willing to approach to it.
