The Name Hasher uses IBM Global Name Recognition technology
to enhance name hashing by creating variant hashes for each incoming
name. The variant name hashes enable entity resolution to use fuzzy
name matching during name analysis and scoring.
The following scenarios show the benefits of when you
might use the Name Hasher:
- When much of the data can be matched only on the <NAME> segment
- When much of the data can be matched only on the <NAME> segment
and most of the data does not conform to the Anglo culture first name,
middle name, and last name notation
Using the Name Hasher with the Name Manager name scoring
algorithm provides the ability to classify names for culture and accurately
compare and score names on the candidate list in a culturally-sensitive
context.
The Name Hasher is not enabled by default. You use
the Configuration Console to enable the Name Hasher and the associated
DQM functions.
Attention: Contact IBM Services or Support
if you are upgrading from Name Hasher from product versions 8.0 or
4.2, and if you are an existing customer enabling Name Hasher for
the first time. In both cases, without assistance from IBM Services
or Support, entity resolution of new data fails when compared against
the existing data in the entity database.
