Cross-Scenario Inference Based Event-Event Relation Detection.

Event-Event Relation Detection (RD2e) aims to detect the relations between a pair of news events, such as Causal relation between Criminal and Penal events. In general, RD2e is a challenging task due to the lack of explicit linguistic feature signaling the relations. We propose a cross-scenario inference method for RD2e. By utilizing conceptualized scenario expression and graph-based semantic distance perception, we retrieve semantically similar historical events from Gigaword. Based on explicit relations of historical events, we infer implicit relations of target events by means of transfer learning. Experiments on 10 relation types show that our method outperforms the supervised models.
