Filtering Record Pairs

You can filter pairs by priority, assignment, and other characteristics.

Open filtering options by selecting Filter filter on the Pairs page.

To close the filters panel, select Filter filter again.

Tips for Filtering Pairs

To use filters to review and label pairs effectively:

  • Prioritize high-impact pairs.
  • For a "To-do" list, set the My assignments filter to Open. Alternatively, set the My response filter to No Response.
  • Attribute filters allow you to select attributes and how similar or dissimilar their values are.
  • To reduce the number of pairs that display further, you can apply more than one filter.

Filtering Options




  • High-impact pairs: Pairs that have the most utility for training the machine learning model.
  • Pairs with comments.


  • My assignments: Pairs that are assigned to you.
  • All expert assignments: All pairs assigned for review.

When you select either filtering option, you can further filter to assignments that are skipped, open, or completed.


Filter by expert, Tamr Core, or your own responses to Tamr Core's suggestions for pairs, as well as by Tamr Core's confidence in its own suggestions.

  • Has expert responses: Pairs with a response from any project contributor.
  • Inferred and Learned Pairs: If one or both of these optional features are enabled, pairs that Tamr Core inferred labels for based on changes in record grouping keys, or pairs learned from cluster verification. See Grouping Obvious Duplicates or Learned Pairs.
  • My response: Pairs where your response is one of Anything, Match, No match, Skip, or No Response.
  • Experts agree on: Pairs where all contributors agree on Match, No match, Skipped.
  • Verified response: Pairs where the expert response has been verified as Match, No match, Anything (that is, either match or no match), or Nothing.
  • Tamr's response: Pairs where Tamr Core's response is Match, No Match, or Anything (either match or no match), or Nothing.
  • Tamr's confidence: Pairs where Tamr Core's confidence is High, Medium, or Low.


  • Show pairs from: Select source dataset(s) to view pairs from.
  • Top row from: The first in a pair can be selected from a specific source.
  • Bottom row from: The second in a pair can be selected from a specific source.

Note: For a mastering project that includes the record grouping step, the error message “No record pairs matching your filters” appears if groups contain records from a dataset that you do not select.

Attribute SimilaritiesFilter by the similarity of selected attributes and the specified similarity score range.When Tamr Core pairs two records, it compares the values for each attribute and calculates a similarity score from 0 to 100 for that pair of values. This filter option can help you find and label pairs that, based on your knowledge of the data, have a greater likelihood of matching or not matching. Because Tamr Core cannot compute a similarity score if one or both of the values are null, empty, or blank, you can also define a filter for pairs that do not have a similarity score for an attribute. Enable the Pairs without similarity scores toggle.See example below of filtering by attribute similarity.

Filtering pairs based on attribute similarity.
