System and method for creating a searchable word index of a scanned document including multiple interpretations of a word at a given document location

摘要

Multiple recognition engines ( 110 ) provide different interpretations ( 116 ) of a word at a given location within a scanned document ( 108 ). A word node corresponding to each unique interpretation is stored within a word index ( 102 ), with each word node being linked to word nodes of previously and subsequently recognized words.
