Date of birth precision is the scoring process used by entity resolution to determine whether two compared dates of birth represent the same date.
This comparison takes into account various measures of similarity of the date of birth strings including: integer positions, transpositions, and deltas of day, month, and year values. The measures are analyzed to determine an likeness score between 2 and 100. You can configure date of birth precision settings based on four categories of similarity:
The system provides a pre-configured setting of Tight as the minimum level of likeness for a resolution rule to consider two compared dates of birth to be the same. Changing this setting will affect the number of matches and can affect the number of entity resolutions performed by the system. Carefully consider changes to this setting and be sure to test any changes before implementing them in a production environment.
