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
