ABSTRACT:
Various technologies and techniques are disclosed that identify possible incorrect recognition results. Handwritten input is received from a user. A recognition operation is performed on the handwritten input to produce an initial recognition result. A possible incorrect recognition is identified using the self-consistency process that identifies the possible incorrect recognition when the initial recognition result is not consistent with a normal writing style of the user. The self-consistency process performs a comparison of the initial recognition result with at least one sample previously provided by the user. If the comparison reveals that the initial recognition result is not consistent with the at least one sample, then the result is identified as possibly incorrect. A classifier confidence process can be alternatively or additionally used to identify a possible incorrect recognition result. The user interface for displaying the final result can be modified as appropriate given the possible incorrect recognition result.
