Creates a builder backed by the provided map.

Method Detail

enabled

public CompleteLabelFilterDescriptor.AttributeBuilder enabled(boolean value)

Remove truncated phrases. Tries to remove "incomplete" cluster labels. For example, in a collection of documents related to Data Mining, the phrase Conference on Data is incomplete in a sense that most likely it should be Conference on Data Mining or even Conference on Data Mining in Large Databases. When truncated phrase removal is enabled, the algorithm would try to remove the "incomplete" phrases like the former one and leave only the more informative variants.

labelOverrideThreshold

public CompleteLabelFilterDescriptor.AttributeBuilder labelOverrideThreshold(double value)

Truncated label threshold. Determines the strength of the truncated label filter. The lowest value means strongest truncated labels elimination, which may lead to overlong cluster labels and many unclustered documents. The highest value effectively disables the filter, which may result in short or truncated labels.
