Unified Scores table¶
The Unified Scores table records all pairwise comparison scores and match categories for all groups of records. For each group of records, records all pairwise scores that are present between records within that group.
The Unified Scores table is added to databases in the Customer 360 page when:
The Stitch QA database is added using the “Stitch QA” database template.
A customer 360 database is added using the “Customer 360” database template.
A table is added to a custom database using the Unified Scores table as a passthrough table.
Use with Stitch QA¶
The Unified Scores table is the foundation for the Detailed Examples table in the Stitch QA database, which is the starting point for any quality review of Stitch output and is an important part of the Stitch QA workflow.
Use with Customer 360¶
The Unified Scores table enables using the Amperity ID to discover information about how groups of records were scored and to verify those scores against other data points.
Important
The Unified Scores table should not be used outside of the Customer 360 page. It should not be used to build queries or segments or be configured to send data to downstream workflows.
Column reference¶
The Unified Scores table contains the following columns:

Amperity ID |
String |
The unique identifier assigned to clusters of customer profiles that all represent the same individual. The Amperity ID does not replace primary, foreign, or other unique customer keys, but exists alongside them within unified profiles. Note The Amperity ID is a universally unique identifier (UUID) that is 36 characters spread across five groups separated by hyphens: 8-4-4-4-12. For example: 123e4567-e89b-12d3-a456-426614174000

Score |
Float |
A score has a value from “0.0” to “5.0” that represents the combined score assigned to the record pair by Stitch. A score has two parts: the score is on the left side and the score’s strength is on the right. The record pair score correlates to the match category, which is a classifier applied by Amperity to individual record pairs. The record pair score corresponds to the classification:
The record pair strength represents the strength of the record pair score. It is a two digit number. For example: .31 is a lower strength and .93 is a higher strength. Note Scores are shown for records that end up in the same cluster, including any scores that are below threshold. Scores are not shown for records that do not end up in the same cluster.

Match Category |
String |
A match category is a classifier that applies to an individual record-pair within a cluster of record-pairs. The match category is the result of this classification.

Match Type |
String |
The score. Possible values: “scored”, “scored_transitive”, and “trivial_duplicate”. A match is assigned “scored_transitive” when that match was not identified during blocking. For example: three records (A, B, and C). If records A and B and records B and C were identified as matching during blocking, all three records will end up in the same group of records for pairwise comparison. Records A and C have a transitive connection. |
