This difference is reflected in the way that major news stories often emerge: an initial single, focussed story emerges but is later replaced with several potentially overlapping sub-stories covering different aspects of the story. Our results suggest that a dynamic approach may be required for newsworthy topic detection, finding an initial clear burst and subsequently seeking more subtle and overlapping topics.

2]. 1 The three data sets differ in the rates of tweets, determined by the popularity of the topic and the choice of filter keywords. The mean tweets per minute (tpm) were: Super Tuesday, 832 tpm; FA Cup, 1293 tpm; and US elections, 2209 tpm. eu/results/datasets/72-twitter-tdt-dataset. 30 C. Martin et al. 41 s respectively.

To generate the sets of Tweets used in the evaluation, we crawled Twitter during the events using appropriate sets of filter keywords, such as the names of the participants.
