Weakest match

Use this query to identify the lowest-scoring record pair, also referred to as the weakest match, within every Amperity ID cluster to improve the overall quality of Stitch results.

Note

There should be a notable decline over time for the number of clusters in which the weakest match is below the Stitch threshold. These clusters are required to have transitive connections to other high-quality pairs. If records are matched in clusters that do not have transitive connections to other high-quality pairs, it’s important to investigate those clusters to confirm if they were accurately clustered together and do have transitive connections to other high-quality pairs.

When to use
