Match Analysis

You can analyze match rules to check the number of match token phrases generated.

The number of match token phrases generated for match groups is very important for the matching process. The number of match token phrases generated has a direct impact on the performance of a match rule. The Analyze Match Rules job analyzes the generation of match token phrases and the performance of the match rules configured in your tenant.

For the generation of match token phrases, the Analyze Match Rules job checks for the following:
  • If too many tokens are generated by a subset of the processed entities than the specified threshold for the specified match groups.
  • If too few tokens are generated by a subset of the processed entities than the specified threshold for the specified match groups.

To analyze the performance of match rules, this job checks the number of match pairs generated for the specified set of entities.

You can use this information to improve your tokenization scheme or tune your match rules to ensure that matching in your tenant produces the desired results.
