(Plagarized from Wikipedia) An n-gram is a sub-sequence of n items from a given sequence. n-grams are used in various areas of statistical natural language processing and genetic sequence analysis. The NGrams class is a map/table of counts keyed by n-gram sequences of characters or words. The idea is this can be a handy model for classification/clustering/grouping applications.
