EventPro

EventPro is a module for event detection and classification in a text. It annotates events following the TimeML specifications and classifies them in one of the seven TimeML classes (REPORTING, PERCEPTION, I_ACTION, etc.). As an example, the word "annunciato" (announced) is an event of type REPORTING expressed by a verb, while the word "tagli" (cuts) is an event of type OCCURRENCE expressed by a noun. Both event recognition and classification are based on a statistical classifier. EventPro is available for Italian and English with pre-trained models in the news domain.

Example


Algorithm: EventPro uses Yamcha for feature extraction and SVM as a classification algorithm.

Resources: EVENTI (Italian) and TempEval 3 (English).

Evaluation benchmark: EVENTI at Evalita 2014 and QA-TempEval 2015 (English).
