TEXT CORRECTION METHOD AND RECOGNITION METHOD

WIPO Patent Application WO/2012/004955

A1

Provided is a device that, with respect to recognized sentences that include errors and that are the output of voice recognition or the like, efficiently performs presentation of estimation/correction candidates of misrecognized sections and performs correction processing prioritizing important errors. A feature word list that is a collection of feature words is extracted from a recognized sentence by means of feature word extraction processing, and a term among the terms in the recognized sentence that is not contained in the feature word list is determined to be a term (hereinafter referred to as an anomalous word) that is not appropriate to the context, and it is determined that there is the possibility of an error. The degree of similarity between each term determined to be anomalous and each of the words included in the feature word list is compared, and the terms for which the degree of similarity is determined to be high are considered correction candidates with respect to anomalous words. In this way, feature words are extracted ahead of time.
