Recommended Usage
- Hybrid deduper, where a single incoming record can quickly be evaluated independently against each record in an existing large master database.
- Batch processes where NGRAM is set on a single non-first matchcode component.
- Databases created with abbreviations or similar word substitutions.
- Multi word field data where a trailing word does not appear in every record in the expected group or data contains acceptable variations of one of the keywords.
Not Recommended For
- Databases where the number of errors with relation to the string length result is a small number of common substrings.
- Gather/scatter, survivorship, or record consolidation of sensitive data.
- Quantifiable data or records with proprietary keywords not associated in our knowledgebase tables.
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.
