SimpleLabelAssigner, UniqueLabelAssigner

public interface ILabelAssigner

Assigns labels to base vectors obtained from the factorization.

Method Summary

void	assignLabels(LingoProcessingContext context, org.apache.mahout.math.matrix.DoubleMatrix2D stemCos, com.carrotsearch.hppc.IntIntOpenHashMap filteredRowToStemIndex, org.apache.mahout.math.matrix.DoubleMatrix2D phraseCos) Assigns labels to base vectors found by the matrix factorization.

Method Detail

assignLabels

void assignLabels(LingoProcessingContext context,
                  org.apache.mahout.math.matrix.DoubleMatrix2D stemCos,
                  com.carrotsearch.hppc.IntIntOpenHashMap filteredRowToStemIndex,
                  org.apache.mahout.math.matrix.DoubleMatrix2D phraseCos)

Assigns labels to base vectors found by the matrix factorization. The results must be stored in the LingoProcessingContext.clusterLabelFeatureIndex and LingoProcessingContext.clusterLabelScore arrays.

Parameters:

context - contains all information about the current clustering request

stemCos - base vector -- single stems cosine matrix

filteredRowToStemIndex - mapping between row indices of stemCos and indices of stems in PreprocessingContext.allStems

phraseCos - base vector -- phrase cosine matrix
