An optical character recognition system which can extract information from documents into machine readable form for selected inclusion into a data base uses human classification through the use of translucent ink pens of colors which correlate to field designations. The ink pens, commonly known as highlighters, are used to mark the selected text. An optical scanner reads the marked document and converts it to electronic data which is stored into data base fields according to the color marked regions.
