Class LinearPosition

java.lang.Object

edu.illinois.cs.cogcomp.edison.features.factory.LinearPosition

All Implemented Interfaces:

FeatureExtractor

public class LinearPosition
extends Object
implements FeatureExtractor

Given two constituents, indicates whether the first is before or after the other or have an overlap.

Important note: To be able to specify the two constituents as input, the feature extractor assumes the following convention: The constituent that is specified as a parameter to the getFeatures function has an incoming relation from the first constituent. Furthermore, this incoming relation should be the only such relation.

This convention does not limit the expressivity in any way because the two constituents could be created on the spot before calling the feature extractor.
