Abstract

In this paper, we investigate a semi-supervised method, that is, self-training algorithm in event detection and type recognition. First, we get two kinds of feature vectors of sentences for event detection and type recognition task respectively. Second, we use self-training algorithm to filter the non-event instances and identify type for every event instance. The experimental result on the ACE2005 corpus shows that our model using self-training algorithm can identify the majority of non-event instances and also has a good precision and recall rate in event type recognition.
