Enabling the IBM Global Name Recognition Name Hasher feature

Enabling IBM Global Name Recognition Name Hasher feature for UMF <NAME> segment data quality processing can improve name parsing, culture classification, and name hash generation.

Before you begin

If you are enabling the Name Hasher on an existing installation for the first time, contact IBM Services or Support for assistance. All existing data from all data sources must be reloaded to prevent the entity resolution of new data from failing against the existing data in the entity database.

About this task

These instructions are summaries of the tasks that must be completed to enable the Name Hasher. All steps are completed using the Configuration Console. Click the link to get the step-by-step instructions for each task.

Procedure

  1. Enable the DQM function 282 to create name hashes. This function turns on the Name Hasher functionality within the pipelines. If you used the Name Hasher prior to product version 8.0 fix pack 2, see the instructions for migrating to the upgraded Name Hasher. You might want to reuse some of the parameters used by DQM 282.
  2. Enable the DQM function 610, so that the Name Hasher can create composite name hash attributes.
  3. Configure the Default w/ Name only candidate builder for enhanced name hashing.
  4. Configure each data source for enhanced name hashing.
  5. Disable full name parsing in DQM function 252. The Name Hasher creates name hash variants for all name parts, not just the full name.
  6. Configure DQM rule 255 for enhanced name hashing By completing this step, you keep the name standardization capability of DQM 255, but you disable the standard name hashing to use the enhanced name hashing of the Name Hasher. You also ensure that pipeline validation check of verifying that DQM 255 is enabled does not fail and shut down the pipelines.
  7. Enable the DQM function 260 for the UMF <NAME> segment. This DQM function assigns name cultures to incoming name data. The Name Hasher requires name culture to apply multi-cultural expertise to enhanced name hashing. Make sure that Name Manager is turned on. (Typically, Name Manager is on.) If you enable the DQM rule 260 and Name Manager is not turned on, DQM 260 rule fails, and the pipelines shut down.
  8. Set the system parameters for the Name Hasher. By completing this step, you configure the necessary system parameters for the pipelines used during enhanced name hashing.
