Searching for similar records using a Neural Network for inexact matching

Many applications require the matching of names, and although exact matching is often used, inexact matching is useful when we want to take into account the possibility of spelling errors. Soundex codes can provide a form of inexact matching but even exact matching of Soundex codes can miss obvious matches like fog and phogg. Neuro-fuzzy Soundex combines the extended Soundex codes provided by the Soundex supernode with neuro-fuzzy (inexact) matching to provide a very flexible name and word matching technique.
