发明名称 Optical character recognition system having context analyzer
摘要 <p>An optical character recognition (OCR) system (2) is provided, in which syntactical and semantic rules (6), provided along with an input image (4) to be scanned and applicable to the contents of the scanned image, are used in connection with the results of the OCR scan to identify the scanned characters. As a result, the recognition rate and confidence are enhanced. By providing the checking based on syntactical and semantic rules within the OCR system (2), application programs (8) which would receive and use the OCR results are freed from the added burden of having to perform their own syntactical and/or semantic checking on the OCR results the application programs (8) receive from the OCR system (2). <IMAGE></p>
