Proof reading of text data generated through optical character recognition

A non-transitory computer program product for supporting proof reading of text data generated through optical character recognition, the computer program product comprising a computer readable storage medium having computer program code embodied therewith, the computer program code executable by a processor to perform:

• preparing a first proof reading tool for performing carpet proof reading on the text data;
• preparing a second proof reading tool for performing side-by-side proof reading on the text data;
• recording a log of proof reading operations having been performed by using the first proof reading tool and the second proof reading tool;
• and
• determining, for each attribute serving as units in which carpet proof reading is performed with the first proof reading tool, whether or not to use the first proof reading tool in proof reading of the attribute, by comparing a first estimated value of a time taken when proof reading is performed by using the first proof reading tool with a second estimated value of a time taken when proof reading is performed by using the second proof reading tool without using the first proof reading tool, the first and second estimated values being calculated on a basis of the log.
