public class IndexFeatures
extends java.lang.Object

Identifies and compares the features of a GraphNode that are relevant for anaphoric reference, for example person, gender, and number.

indexFeaturesMatch

public static final boolean indexFeaturesMatch(GraphNode node1,
                                               GraphNode node2,
                                               int verbosity)

This static method returns true if the two GraphNodes agree in their index features and are therefore candidates for the coreference relation

Examples: "sie" and "die Frau", "sie" und "die Kinder" and so forth.

Parameters:

node1 - The first node to be matched against the index features.

node2 - The second node to be matched against the index features.

verbosity - The level of verbosity.

Returns:

True if the given GraphNodes agree in their index features.

indexFeaturesMatch

public static final boolean indexFeaturesMatch(GraphNode node1,
                                               GraphNode node2)

This static method returns true if the two GraphNodes agree in their index features and are therefore candidates for the coreference relation

Examples: "sie" and "die Frau", "sie" und "die Kinder" and so forth.

Parameters:

node1 - The first node to be matched against the index features.

node2 - The second node to be matched against the index features.

Returns:

True if the given GraphNodes agree in their index features.
