Class BaseCluster

java.lang.Object
  org.carrot2.filter.stc.algorithm.BaseCluster

public final class BaseCluster
extends Object

A base cluster in the STC algorithm. A base cluster is basically a Node in suffix tree with an associated score and assigned later links to other nodes in base clusters graph.

Field Summary

protected int	id id number assigned by the creator of this object
protected List	neighbors Base clusters this object has links to in base clusters graph
protected Phrase	phrase This node's phrase
protected float	score Score of this base cluster (passed to constructor)

Constructor Summary

BaseCluster(PhraseNode node, float score)
Public constructor for BaseCluster requires a node and precalculated score

Method Summary

void	addLink(BaseCluster neighbor) Adds a link to another BaseCluster (used when constructing base clusters graph
int	getId() getter for id
List	getNeighborsList() Retrieves the list of neighbors of this base cluster
PhraseNode	getNode() Getter for node variable
Phrase	getPhrase() Getter for this base cluster's phrase object
float	getScore() Getter for score variable
boolean	isMerged()
void	setId(int id) Setter for id
void	setMerged(boolean merged)
