Consonants

Specifics

Only consonants will be compared. Vowels will be removed. ‘Y’ is defined as a vowel in this algorithm.

Summary

This algorithm removes vowels from the string and compares two strings based on their consonants.

Returns

Returns a match if two strings’ consonants match exactly.

Recommended Usage

Hybrid Deduper, where a single incoming record can quickly be evaluated independently against each record in an existing large master database.
Databases created via real-time data entry where audio likeness errors are introduced.
Databases of US and English language origin.

Not Recommended For

Database where disemvoweling was used to reduce storage space (https://en.wikipedia.org/wiki/Disemvoweling).

Do Not Use With

UTF-8 data. This algorithm was ported to MatchUp with the assumption that a character equals one byte, and therefore results may not be accurate if the data contains multi-byte characters.
