Shingling

Definition(s)

A Feature Engineering method in which the Features consist of all N-Grams in a text, for some number N. For example, the Trigram Shingling of the text “To be or not to be” consists of the Features “to be or”; “be or not”; “or not to”; and “not to be.” Note that the Features overlap one another in the text, suggesting the metaphor of roof shingles. 1
