摘要 

【目的】识别并对比分析国内外健康问答社区用户信息需求, 总结演变规律和探究演变原因。【方法】选取“慢友帮”和“DailyStrength”糖尿病群组用户问答数据, 基于主题和时间视角, 利用主题编码、社会网络和内容分析方法, 对比分析主题分布、演化及共现规律。【结果】国内外社区用户核心需求都是“疾病如何治疗”; 且对于慢性病社区而言, “饮食”主题与其共现主题关系很密切。【局限】尚未将问答相关程度纳入分析框架, 对主题演变及内容研究不够深入。【结论】国内社区处于发展期, 国外社区处于稳定期; 国内社区具有“问答属性”, 而国外社区兼具“问答属性”和“社交属性”。

Abstract

[Objective] This paper identifies and analyzes the information needs of domestic and international question and answer health communities, aiming to find the patterns of regulation evolutions and explore the reasons. [Methods] First, we selected diabetes related data from ManYouBang and DailyStrength. Then, we compared topic evolution and co-occurrence, from the perspectives of theme and time, and using theme coding, social network and content analysis. [Results] The essential needs of HCQA users were “how to treat the disease”. For the chronic disease community, the “diet” theme was closely related to its co-occurrence themes. [Limitations] Our research did not examine the relevance of answers to questions, thus more in-depth study is needed on the topic evolution and content. [Conclusions] Domestic HCQA community is still developing while their foreign counterparts are stable. The former has only “question and answer attribute” while latter has both “Q&A” and “social” attributes.
