1. Intra-sentence event-event classifier

	Pruning Heuristics: If none of the conditions listed below are satisfied then the event pair is pruned, 
	otherwise the pair is passed onto the classifier. 
	* are the events in the pair consecutive?, or
	* is there only one entity between the events in the pair?, or
	* are the two events the first and the last events, respectively, in the sentence?

2. Intra-sentence event-time classifier

	Pruning Heuristics: If none of the conditions listed below are satisfied then the entity pair is pruned, otherwise the pair is passed onto the classifier.
	* are the entities in the pair consecutive?, or
	* is there only one entity between the event-time pair?, or
	* are the two entities the first and the last entities, respectively, in the sentence?

3. Inter-sentence classifier for events in adjacent sentences

	Pruning Heuristics: If the condition below is not satisfied then the event pair is pruned, otherwise the pair is passed onto the classifier.
	* are the paired events from adjacent sentences either in the first and last positions, or the last and first positions in their respective sentences?

4. Inter-sentence coreferent event-event classifier

	Pruning Heuristics: If the condition below is not satisfied then the event pair is pruned, otherwise the pair is passed onto the classifier.
	* do events in the pair have matching head words?
