媒体注意力动态

Dynamics of Media Attention

V. A. Traag, R. Reinanda, J. Hicks, G. van Klinken

摘要:

人类注意力动力学的研究分析了注意力是如何集中在特定的主题,问题或人。在在线社交媒体中,有明显的外生冲击、突发动态和指数或幂律寿命分布的迹象。在这里,我们分析了传统媒体的注意力动态,重点放在报纸文章中的人的共同出现。结果与在线社交网络和注意力大不相同。不同的制度似乎在两个不同的时间尺度上运作。在短时间尺度上,我们看到了突发动态和快速衰减的边缘寿命和注意力的证据。这种行为消失了较长的时间尺度,并在该制度中,我们发现泊松动力学和较慢的衰减寿命。我们建议,级联泊松过程可能会发生,在很长的时间尺度上以恒定的速率出现的问题,在较短的时间尺度上更快的动态。

英文摘要:

Studies of human attention dynamics analyses how attention is focused on specific topics, issues or people. In online social media, there are clear signs of exogenous shocks, bursty dynamics, and an exponential or powerlaw lifetime distribution. We here analyse the attention dynamics of traditional media, focussing on co-occurrence of people in newspaper articles. The results are quite different from online social networks and attention. Different regimes seem to be operating at two different time scales. At short time scales we see evidence of bursty dynamics and fast decaying edge lifetimes and attention. This behaviour disappears for longer time scales, and in that regime we find Poissonian dynamics and slower decaying lifetimes. We propose that a cascading Poisson process may take place, with issues arising at a constant rate over a long time scale, and faster dynamics at a shorter time scale.
