Event Hypergraph Model and Event Type Recognition

This paper develops an event type recognition approach based on hypergraph to avoid the impact of independence assumption in vector space model.The approach firstly represents the Multi-ordering relationship among event elements by an event hypergraph.Then the approach displays the attribute and its structure of one(series of) event(s) in various dimensions by the event hypergraph model integrated by the type component and dimension component.Lastly the approach computes the event similarity by the attribute and its structure.The experimental results showed that this approach can increase the efficiency of recognition to 83.0%(F-score),which is better than SVM or ME based on vector space model.
