The Luhn summarizer returns the most significant sentences of a text by : 1 - Calculating frequencies ratio of significant terms (discounting ones with ratio outside an arbitray range, ie "normalized"). 2 - Calculating each sentence rating ((number of significant terms)² / (greatest distance between two significant terms)). 3 - Sorting sentences according to their weight and returning the first n of them.
