Direct Known Subclasses:

LabeledBinaryExtraction, NormalizedBinaryExtraction

public class ChunkedBinaryExtraction
extends SpanExtraction

Represents a binary extraction from a ChunkedSentence. A binary extraction has three parts: two arguments (arg1 and arg2) and a relation (rel). Each of these parts corresponds to a disjoint span of words in a sentence. The relation is represented as a ChunkedExtraction object, and the two arguments are represented as ChunkedArgumentExtraction objects.
