 Orange NMF is an add-on for Orange_ data mining software package. It provides non-negative
 matrix factorization algorithms (NMF) through NIMFA_ and robust singular value decomposition (rSVD).
-it includes pre- and post-data processing widgets. The pre-processing widgets are designed to deal with
-normalizations, missing data, etc. The post-processing widgets are designed to view and assess the results
-of matrix factorization.
+It includes widgets that deal with missing data in input matrices, their normalizations, viewing and assessing
+the quality of matrix factors returned by different matrix factorization algorithms.
