transitiveClosure

public static int[] transitiveClosure(RelationSet relSet,
                      String relationName,
                      int annotationId)

Computes the transitive closure for symmetric transitive relations (such as co-reference). Given a relation name and a seed annotation ID, this method returns the IDs for all annotations that are:

• the seed annotation
• in the given relation (regardless of position) with another annotation from this set

Parameters:

relSet - the RelationSet used as context.

relationName - the relation to be used for computing the closure.

annotationId - the ID for the seed annotation.

Returns:

an array containing the IDs of all the annotations in the closure.
