Class NestedExtraction

      edu.washington.cs.knowitall.extraction.NestedExtraction

public class NestedExtraction
extends edu.washington.cs.knowitall.nlp.extraction.SpanExtraction

A class that represents a nested relation. An example of a nested relation is theoryThat(heliocentrism, centerOf(sun, universe)). A nested relation has the following components:

• Argument 1 - e.g. heliocentrism
• Nested Relation - e.g. theory that
• Argument 2 - e.g. sun
• Base Relation - e.g. center of
• Argument 3 - e.g. universe

Arg2, the base relation, and arg3 are collectively referred to as the base extraction.
