A Dynamic Evolutionary Framework for Timeline Generation based on Distributed Representations
Table 2. Performance of models on Crisis data
['Methods', 'ROUGE-1', 'ROUGE-2', 'ROUGE-S']
Regression method is shown as a strong supervised baseline, and Wang’s method is the past state-of-the-art method on this dataset. They don’t explicitly consider much natural feature of the timeline, such as coherence and overall, thus fails to capture the semantic relations between events in short titles. We lead throughout the timeline by the coherence of the events and a global view of the topic. The same hyper-parameters as 17 Timelines are set, and it shows that Viterbi timeline can improve the performance significantly in general.
