Class DirectConfirmationBasedCoherence

java.lang.Object

org.aksw.palmetto.DirectConfirmationBasedCoherence

All Implemented Interfaces:

Coherence

public class DirectConfirmationBasedCoherence
extends Object
implements Coherence

This type of coherence measure is a non-vector-based coherence. It uses only the probabilities derived from the data source to caluclate the coherence.
