与传统 Web 搜索相比,社会化搜索为新一代互联网用户获取信息提供了很多便利,无论对于搜索过程还是搜索结果而言,都更具个性化、情境化与智能化.然而,信息价值问题始终困扰着社会化搜索平台的健康发展.本研究聚焦于不同用户满意度及任务复杂性水平下,社会化搜索平台中用户的信息价值感知差异性,采取准实验研究方法来验证提出的三个研究假设.研究结果表明,①用户感知信息价值的各项指标与用户满意度呈正相关;②"新颖性"、"原创性"、"启发性"与任务复杂性呈正相关,其余的10个指标则呈负相关;③任务复杂性和用户满意度能够对信息价值指标产生交互作用,且结果差异较大.相关研究结论有助于社会化搜索平台明晰用户的个性化需求,并对提升用户信息搜索能力及信息素养有所裨益.%Compared with the traditional Web search, social search provides users with increased convenience. It is more personalized, contextualized, and intelligent both for the search process and results. However, some issues with information value are always great concerns for the healthy development of social search platforms. In this study, we focus on the user-perceived difference of information value in the context of social search from two perspec-tives—user satisfaction and task complexity—and also conduct quasi-experiments to verify three proposed research hypotheses. Findings reveal the following: ① user perceived difference on information value and user satisfaction are positively correlated; ② variables such as novelty, originality, and enlightening associated with task complexity are positively correlated, while the other 10 indicators show negative correlations; ③ an interaction effect exists between task complexity and user satisfaction on information value, and the results are varied among different indicators. Results yield some implications for explicating users' personal information needs on social search platforms and betters our understanding of the facilitation of information searching ability and information literacy.and betters our understanding of the facilitation of information searching ability and information literacy.
