From: Coreference based event-argument relation extraction on biomedical text
Formula | Description |
|---|---|
event(i) ⇒ ∃t.eventType(i, t) | If there is an event there should be an event type |
eventType(i, t) ⇒ event(i) | If there is an event type there should be an event |
role(i, j, r) ⇒ event(i) | If j plays the role r for i then i has to be an event |
event(i) ⇒ ∃j.role(i, j, Theme) | Every event relates to need at least one argument. |
