Abstract：Currently, semi-supervised or unsupervised event extraction remains a challenge. According to the nature of Chinese language, this paper proposes a dual-view-based bootstrapping approach to extract event patterns. According to a small set of seeds, it applies a cross filtering method to two views, document relevance and semantic similarity, and extract new patterns in each iteration. Our experimental results show our system outperforms the existed systems.
