Abstract: A method and apparatus which enables a computer to understand and manipulate minimally formatted text of such documents as resumes, purchase order forms, insurance forms, bank statements and similar items is disclosed. The documents are digitized by an optical scanner and translated into ASCII text by an optical character reader. The invention manipulates the digital image of the document to find blocks of contiguous text. After separating the text by block, each block is converted into an ASCII character file. Next, these files are processed by a Grammar, which uses pattern matching techniques and syntax rules to enable the host computer to understand the text. After further manipulation by the invention, the text is either stored or outputted in a form which greatly facilitates its use and readability.
