From: Measuring and monitoring collective attention during shocking events
Effectiveness of preserving the most attended hashtags. The plots show the performance, calculated based on precision@L with \(L=100\), for preserving the most attentive hashtags using different sampling methods, tested on the Paris and Brussels datasets. The vertical dotted lines indicate the time of the events. The performance is reported for each hour within the entire week centered on the event happening time (three days before and three days after the attacks). The three methods, CommonTag_RW, CoPerplexity_RW, and CoPerplexity_PRW are more robust under various conditions.
