Claim One:
1. A cluster storage apparatus for outputting groups of valid alpha words as potential candidates for the correct form of an alpha word misrecognized by an OCR machine, comprising: a two-dimenational array of alpha word read only storage locations, each location having a group of alpha words arranged such that adjacent locations contain alpha words having similar OCR misread propensities; means for assigning numeric values to the characters of the input alpha word based upon the read reliability of the characters; a first-dimensional accessing means for addressing said locations based upon the values assigned to the characters of which the input alpha word is composed; a second-dimensional accessing means for accessing said locations based upon the number of characters in said input alpha word; said first-dimensional accessing means calculating the first-dimensional address as a magnitude ##EQU7## where L.sub.N is the numeric value assigned to each alpha character; whereby an input alpha word which is potentially in error can be associated with that portion of the read only storage which contains potential candidates for the correct form of the input alpha word.
