      void assignLabels​(LingoProcessingContext context, org.carrot2.math.mahout.matrix.DoubleMatrix2D stemCos, com.carrotsearch.hppc.IntIntHashMap filteredRowToStemIndex, org.carrot2.math.mahout.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
