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.

Getting ready

This recipe uses the following files:

  • Datafile: names.txt

  • Stream file: Neuro_Fuzzy_Soundex.str

  • Supernode library file: Soundex_Digits.slb

How to do it...

To search for similar records using a neural network for inexact matching, perform the following steps:

  1. Open the stream file (Neuro_Fuzzy_Soundex.str) by going to File | Open Stream.

  2. Zoom in to the supernode Target. This selects a specific target record...
