Patent Images
1. A method comprising:
- receiving, at a processor, a set of uncertain characters obtained as a result of a recognition process of a text image, the set of uncertain characters including an image of an uncertain character, a hypothesis about the uncertain character, and a confidence level associated with the hypothesis;
causing, by the processor, a display device to present to a user the image of the uncertain character from the set of uncertain characters over a text readout;
receiving, at the processor from a user input, marking data for the uncertain character; and
adjusting, using the received marking data, the confidence level associated with the hypothesis about the uncertain character for obtaining a confirmed hypothesis linked to the uncertain character.

Abstract
An improved method for verifying whether a character-recognition technology has correctly identified which characters are represented by character images involves displaying the uncertain character images in place of their respective hypothesis characters in a document being read a verifier. The verifier may mark incorrectly spelled words containing the uncertain character images. Based on the markings, a system adjusts a confidence level associated with the hypothesis about the uncertain character in order to obtain a confirmed hypothesis linked to the uncertain character.

16. A non-transitory computer-readable medium having stored thereon instructions executable by a processor to cause the processor to perform functions, the functions comprising:
-
receiving a set of uncertain characters obtained as a result of a recognition process of a text image, the set of uncertain characters including an image of an uncertain character, a hypothesis about the uncertain character, and a confidence level associated with the hypothesis; causing a display device to present to a user the image of the uncertain character from the set of uncertain characters over a text readout; receiving from a user input marking data for the uncertain character; and adjusting, using the received marking data, the confidence level associated with the hypothesis about the uncertain character for obtaining a confirmed hypothesis linked to the uncertain character. - View Dependent Claims (17, 18, 19, 20)

21. A system comprising:
-
a communication interface configured to receive a set of uncertain characters obtained as a result of a recognition process of a text image, the set of uncertain characters including an image of an uncertain character, a hypothesis about the uncertain character, and a confidence level associated with the hypothesis; a processor configured to; cause a display device to present to a user the image of the uncertain character from the set of uncertain characters over a text readout; receive, via the communication interface from a user input, marking data for the uncertain character; and adjust, using the received marking data, the confidence level associated with the hypothesis about the uncertain character for obtaining a confirmed hypothesis linked to the uncertain character. - View Dependent Claims (22, 23, 24, 25)
