Metaphone 3 information

Question

Does anyone know where code can be found for Metaphone 3 matching for T-SQL or at least something that describes in detail the difference between Double Metaphone and Metaphone 3? I have been working on evaluating different matching algorithms in SQL Server and would like to see how this algorithm performs but can find very little information on it.

Answer 1

Metaphone-3 is a commercial product from http://www.amorphics.com/.

Answer 2

There's a Java implementation of Metaphone3 in the source code of OpenRefine, which is a BSD-Licensed former Google product: Metaphone3.java.
