Abstract

Systems and methods for determining a location of a target in a document. Information compiled from a training document is created, the information comprising a reference and a reference vector tying each reference to the target. The reference is compared to a new reference in a new document to determine if there are any similar references that are the target, wherein similar references are: position similar, or type similar, or both. When the new reference comprises a typo, an optical character recognition (OCR) mistake, or both, the new reference is still determined to be the target because of the new reference's location.
