Method Detail

exactPhraseAssignment

public DocumentAssignerDescriptor.AttributeBuilder exactPhraseAssignment(boolean value)

Only exact phrase assignments. Assign only documents that contain the label in its original form, including the order of words. Enabling this option will cause less documents to be put in clusters, which result in higher precision of assignment, but also a larger "Other Topics" group. Disabling this option will cause more documents to be put in clusters, which will make the "Other Topics" cluster smaller, but also lower the precision of cluster-document assignments.
