Method Detail

setDocClusters

public void setDocClusters(DocClusterSet clusterSet)

Description copied from interface: ClusterModel

This method is equal to calling the setDocCluster method for all clusters.

Specified by:

setDocClusters in interface ClusterModel

Parameters:

clusterSet - all new clusters

getDistance

public double getDistance(IRDoc doc,
                          DocCluster cluster)

Specified by:

getDistance in interface ClusterModel

Parameters:

doc - the document

cluster - the document cluster

Returns:

the distance between the document and the cluster

getClusterNum

public int getClusterNum()

Specified by:

getClusterNum in interface ClusterModel

setFeatureFilter

public void setFeatureFilter(FeatureFilter selector)

Description copied from interface: ClusterModel

A feature selector is set. After that, the excluded features do not count in cluster model any more.

Specified by:

setFeatureFilter in interface ClusterModel

getFeatureFilter

public FeatureFilter getFeatureFilter()

Specified by:

getFeatureFilter in interface ClusterModel

Returns:

the feature selector used for the cluster model
