Step S24: the collation result according to collating in the document the content of revising draws the collation accuracy of collating the user;
Step S25: judge and whether collate accuracy,, otherwise enter step S27 if then enter step S26 greater than preset value;
Step S26: document is collated in output;
Step S27: output information, prompting are collated the user and are collated once more collating document.Next can change step S24 over to.
When obtaining user's collation accuracy, in step S22, specifically can adopt the method for two-way scrambling.
In the method for two-way scrambling, a kind of is that will to discern correct character change at the predeterminated position of identification in the document be other characters, like this in step S24, add up these and come out, the number of words of checking out is accounted for process revise the collation accuracy of the ratio of character sum as this collation user through having how many words to be collated customer inspection in the character of revising.
The another kind of method of two-way scrambling is at the predeterminated position of identification in the document character change of identification error to be the character beyond the correct character of this predeterminated position.Because might exist a certain character usually to be erroneously identified as another character among the OCR result, the press corrector may directly search this another character like this, thereby ignore check and correction to other characters, so this another character can be made amendment, change other characters into, these other characters should not be the correct characters of current location, can impel the press corrector that each character is proofreaded like this, rather than directly search the result of those fallibilities.
When scrambling, can take different scrambling strategies at different collation users.For example collate the user and usually can not collate out, just can carry out scrambling at this characteristics of collating user A for the mistake that exists among some OCR result.Specifically can be before step S22, press the character statistics and collate the collation accuracy of user each character, from being lower than the character of preset value, this collation user's collation accuracy determines one or more characters then, with the character that all or part of described one or more characters in the identification document are corresponding respectively to be obtained when being revised as each character by wrong identification.For example " not " often is identified as " end " such mistake, usually collated user A and ignores, and so just can change " not " that correctly identifies in the identification document into " end ", sees whether collation user A checks to draw.
After step S25, may also comprise and do not collated the individual characters of in step S22, revising that customer inspection goes out, therefore can the content recovery of revising among the step S22 be the content before revising according to the record among the step S22.
