Abstract

A document understanding system capable of document structure analysis together with character recognition system has bee developed and applied to an Optical Character Reader (OCR) system to generate format data automatically. In the registration step, a document with table type construction is scanned by the system as an example. The OCR extracts the rectangular fields from the document, recognizes the characters in the fields and then identifies the label name of it. The OCR generates the format data of each field from the relations between fields and label names by consulting a knowledge-base. In the recognition step, the system recognizes the handwritten Chinese characters (Kanji) using the generated format data.
