The trigger/entity, argument and multi-argument event detectors missed 22, 28 and 6 events, respectively.
The multi-argument event detector combines multiple trigger-argument pairs found by the argument detector to create complete event structures, and assigns an event type to them.
Also, since the multi-argument event detector shares features with the argument detector, as detailed in Table 1, the outputs of argument detectors trained on different source corpora can provide additional features to the multi-argument event detector trained on the target corpus.
Figure 3 illustrates the four different modules of the system, i.e. the trigger/entity detector, argument detector, multi-argument event detector and modification detector, together with sample outputs of each module.
EventMine also performed particularly well on events with multiple arguments, such as Binding and Regulation, since the multi-argument event detector is specifically tailored to detecting of events with multiple arguments, as described in Section 3.1.
EventMine consists of four modules: (i) event trigger detection marks likely triggers and assigns them types, (ii) argument detection identifies likely trigger-argument pairs and assigns them roles, (iii) multi-argument event detection combines trigger-argument pairs into likely event structures and (iv) modification detection assigns modification flags (Negation and Speculation).
"Whatever the arguments, events here 70 years ago left a deep wound and diminished all our humanity," he said.
An approach along these lines sheds light on the intricate properties of past participles and the auxiliaries they occur with, the determinants of auxiliary selection as well as the interplay of argument and event structure.
Typical errors include wrong assignment of arguments, wrong event types, and missed arguments.
In terms of arguments, all event and entity types were generalized as EVENT and ENTITY, respectively.
