#org.bibliome.alvisnlp.modules.RemoveOverlaps

Synopsis

Removes overlapping annotations from a given layer.

Description

org.bibliome.alvisnlp.modules.RemoveOverlaps removes overlapping annotations in the layer layerName.

org.bibliome.alvisnlp.modules.RemoveOverlaps scans each specified layer and finds clusters of overlapping annotations. org.bibliome.alvisnlp.modules.RemoveOverlaps distinguishes three overlapping situations:

1. equal: two annotations have exactly the same span;
2. included: one annotation includes the other completely;
3. overlapping: one annotation overlaps with the head or the tail of the other annotation.

removeEqual, removeIncluded and removeOverlapping specify the behavior for each situation. If the parameter is true, then org.bibliome.alvisnlp.modules.RemoveOverlaps will remove one of the annotations.

annotationComparator controls which annotation is removed.

  By default *org.bibliome.alvisnlp.modules.RemoveOverlaps* removes all kinds of annotations, keeping the longest one.
