Soundex Strategy
The Soundex strategy analyzes words and creates group keys from codes that represent word pronunciation.
Soundex codes begin with the first letter in the word and followed by a series of numbers representing successive consonants. Use the Soundex strategy to assign the same code to words that sound similar. Configure the Soundex depth to define the number of alphanumeric characters that the strategy returns.
This strategy focuses on the sound of words instead of spelling, it can group alternate spellings and minor spelling variations. For example, the Soundex codes for Smyth and Smith are the same.
The Soundex strategy can also group mispronounced words. For example, the Soundex codes for the names Edmonton and Edmonson are the same.
Soundex Strategy Properties
Configure the Soundex strategy properties to determine the Soundex settings that the Key Generator transformation uses to create a group key.
The following table describes the Soundex strategy properties:
Property | Description |
|---|
Soundex Depth | Determines the number of alphanumeric characters returned by the Soundex strategy. The default depth is 3. This depth creates a Soundex code consisting of the first letter in the string and two numbers that represent the next two distinct consonant sounds. |
