public class EventFlattener
extends org.apache.uima.analysis_component.JCasAnnotator_ImplBase

Creates FlattenedRelation instances according to EventMention annotations in the CAS. This means that multiple EventMention annotations that are connected with each other (in the way that one event is the argument of another) are all flattened together in a single annotation. The position of the annotation will be the position of the root event type, i.e. the event that is no argument to another event.

Each EventMention that is not the argument of another EventMention is taken as a kind of 'event structure root'. For these root events, the root itself and all its direct and indirect arguments are assembled to form an instance of FlattenedRelation.

The features agents and patients are only filled for regulations and their subtypes (negative/positive regulation). This is because according to the event definition of BioNLP Shared Task - in which format the EventMention annotations are expected only define causal roles for arguments of those event types.
