Title:

METHOD AND DEVICE FOR VERIFYING RECOGNITION RESULT IN CHARACTER RECOGNITION

Document Type and Number:

WIPO Patent Application WO/2018/024243

Kind Code:

A1

Abstract:

A method and device for verifying a recognition result in character recognition. The method comprises the following steps: constructing, via a recognition result output by a character recognition process, a hidden Markov chain of a character string to be recognized, wherein the recognition result comprises candidate characters of all characters to be recognized in the character string to be recognized, and each of the characters to be recognized corresponds to at least one candidate character (210); solving, according to the hidden Markov chain and a pre-trained state transition matrix, the recognition result, so as to output an optimal path of the candidate characters, wherein a candidate character string comprises at least one candidate character corresponding to each character to be recognized (230); recognizing, according to a state transition probability in the optimal path, a non-Chinese character in the character string to be recognized (250); and verifying, according to the non-Chinese character in the character string to be recognized, the recognition result, so as to feed back a verification result (270).
