Besides, we describe how a freely available system can be tuned to cover also the simplification of phrases, and perform an evaluation comparing different experimental settings. Italiano. La semplificazione lessicale automatica è stata affrontata fino ad ora dalla comunità di ricerca TAL concentrandosi sulla sostituzione di parole singole con altre parole singole.
