Package org.openrefine.clustering

Class Clusterer

java.lang.Object

org.openrefine.clustering.Clusterer

Direct Known Subclasses:

BinningClusterer, kNNClusterer

public abstract class Clusterer
extends Object

Abstract interface for a clusterer.

Once computeClusters has been called, the Clusterer instance is expected to be serializable to Jackson, which is how clustering results are retrieved.

TODO this should be changed: the interface should specify JSON serialization and add abstract methods to retrieve clustering results instead.
