| Outline of Final Research Achievements |
In this research, we have developed an OCR error correction system with the aim to improve the accuracy of digitization of modern documents. We have constructed language resources of modern documents for evaluation of our system and construction of language model for modern documents. We have constructed an error correction system consist of three part, OCR error detection, candidate character generation and selection of a character from candidates. In each part, we use both letter shape information and language model to detect error or to generate candidates. We confirmed that feedback of OCR error correction to the OCR system leads to an improvement of accuracy of the OCR system.
