摘要

许多注意力市场表现出稳定的集中模式,少数制作人吸引并维持了比其他制作人更大的观众份额。这种不平等通常遵循与累积优势相一致的模式,这是一个随着时间的推移,业绩会变得更加复杂的过程。对网络新闻来源的关注具有这些特点;然而,在线观众也分散在许多不同的新闻制作人身上。社交媒体和推荐系统是如何促成这些注意力动态的?在本研究中,我们考察了两种范式模型:累积优势驱动的集中化模型和随机性驱动的碎片化模型。我们根据流行的社交媒体网站Reddit上的新闻来源关注的大规模经验数据集来评估这些模型。虽然我们发现了高度的注意力集中,但我们没有发现随着时间的推移而稳定的受欢迎程度,这是累积优势的特征。更确切地说,消息来源的受欢迎程度的增加和减少似乎是随机的,与随机模型一致。这些结果表明,即使在缺乏强有力的驱动机制的情况下,注意力不平等仍然存在。他们还表示,社交媒体系统可能会破坏对最重要新闻来源的关注积累。追求更公平分配的数字注意力市场需要新的信息组织和分发机制。

Concentration without cumulative advantage: the distribution of news source attention in online communities
Many attention markets exhibit stable patterns of concentration, where a few producers attract and sustain a far greater share of the audience than others. This inequality often follows patterns consistent with cumulative advantage, a process in which performance compounds over time. Attention to news sources online possesses these characteristics; however, online audiences also fragment across many disparate news producers. How do social media and recommender systems contribute to these attention dynamics? In this study, we examine two paradigmatic models: concentration driven by cumulative advantage and fragmentation driven by stochasticity. We evaluate these models against a large-scale empirical dataset of news source attention in the popular social media site Reddit. While we find high levels of attention concentration, we do not find the stable popularity over time that characterizes cumulative advantage. Rather, sources gain and lose popularity seemingly at random, aligning with a stochastic model. These results demonstrate the persistence of attention inequality, even in the absence of a strong driving mechanism. They also suggest that social media systems can undermine the accumulation of attention to the most prominent news sources. Digital attention markets striving for more equitable allocation require novel mechanisms of organizing and distributing information.
