1. A non-transitory computer-readable medium comprising computer-readable instructions for correlating a free text expression of an identity to at least one known identity having a plurality of expressions in a database, said computer-readable instructions comprising instructions that: allow an input of a plurality of expressions associated with an input identity; electronically convert the plurality of expressions to phonetic equivalent codes; compare the phonetic equivalent codes to determine correlations between the codes; correlate at least one of the plurality of expressions with the known identity based on the phonetic equivalent code associated with the at least one expression having a threshold correlation to a phonetic equivalent code associated with the known identity; electronically provide the known identity using the at least one expression having a threshold correlation to a phonetic equivalent code associated with the known identity; allow an input of a verification that the electronically-provided known identity matches a desired identity intended at a time of the input of the plurality of expressions associated with the input identity; and eliminate from the database another of the plurality of expressions having a threshold correlation to the phonetic equivalent code for the known identity.
