Package org.nlpub.watset.graph

Class Watset<V,E>

java.lang.Object

org.nlpub.watset.graph.Watset<V,E>

Type Parameters:

V - the type of nodes in the graph

E - the type of edges in the graph

All Implemented Interfaces:

org.jgrapht.alg.interfaces.ClusteringAlgorithm<V>

public class Watset<V,E>
extends Object
implements org.jgrapht.alg.interfaces.ClusteringAlgorithm<V>

Watset is a local-global meta-algorithm for fuzzy graph clustering.

Watset builds an intermediate undirected graph by inducing different senses of each node in the input graph.

This implementation of Watset is known as Simplified Watset. It does not need a context similarity measure.
