Abstract
A system and method for utilizing distance measures to perform text classification includes text classification categories that each have reference models of reference N-grams. Input text that includes input N-grams is accessed for performing the text classification. A text classifier calculates distance measures between the input N-grams and the reference N-grams. The text classifier then utilizes the distance measures to identify a matching category for the input text. In certain embodiments, a verification module performs a verification procedure to determine whether the initially-selected matching category is a valid classification result for the text classification.
Claims41
