在社交问答社区中，总答案评分是衡量集体智慧的一个指标。通过先动优势的透镜来分析社交问答社区中参与者对答案进行评分和推荐的模式，以解决第一个发布的答案是否比随后提交的答案具有评分优势的问题。作为长期参与者观察的一部分，对提交给Answer Bag社交问答网站的答案的评分按提交顺序进行比较，并对页面浏览量和答案质量进行标准化。结果表明，第一次提交的答案始终比第二次提交的答案多积累大约17%的评分点，并且每个后续答案的评分点往往会下降。讨论了影响评级活动的社会因素以及对解释未来社会问答数据的影响。
Aggregate answer ratings serve as a metric of collective intelligence in social Q&A communities. The patterns by which participants in a social Q&A community rate and recommend answers are analyzed through the lens of first-mover advantage, to address the question of whether the first answer posted has a ratings advantage over those subsequently submitted. As part of a long-term participant observation, ratings for answers submitted to the Answer bag social Q&A site were compared by order of submission and normalized for page views and answer quality. The results suggest that the first-submitted answer consistently accumulates roughly 17% more rating points than the second answer submitted, and that the rating points of each subsequent answer tend to decline. Social factors influencing rating activity and implications for interpreting future social Q&A data are discussed.
