What configuration change could increase a low consolidation rate in identity resolution?

  1. Change reconciliation rules

  2. Increase the number of matching rules

  3. Include additional attributes

  4. Reduce the number of matching rules

The correct answer is: Increase the number of matching rules

Increasing the number of matching rules can significantly enhance the consolidation rate in identity resolution. Matching rules are the criteria that help determine if two pieces of data refer to the same entity. By expanding the range of matching rules, more variations and patterns within the data can be captured, improving the system's accuracy in identifying matches. When more matching rules are introduced, the identity resolution process becomes more comprehensive, considering potential similarities that may have been overlooked with fewer rules. This is particularly important in scenarios where identity data may have inconsistencies or variations in representation (like spelling mistakes or different formats). Additionally, having more matching rules allows the system to leverage additional logic for reconciling records, which ultimately contributes to a higher consolidation rate. A rich set of rules acts like a more sensitive filter that can better discern legitimate matches from false positives, thus improving the overall effectiveness of identity resolution. Although the other options can also play a role in identity resolution, they may not directly contribute to improving the consolidation rate as effectively as increasing the number of matching rules.
