Hello everyone,


We have a quick update regarding the Mismatch Finder tool. In the next deployment scheduled for November 1, the tool will let you report mismatches on qualifiers in addition to the main part of a statement.


A Quick Overview

For those who might not be familiar with the Mismatch Finder, it's a tool that helps spot potential mismatches between Wikidata Items and external databases, presenting them to editors for review and correction. This tool is also used to suggest new statements that should be part of Wikidata, but need a human-review step before adding them. You can explore more about it at Wikidata:Mismatch Finder.


What's on the Horizon?

The Mismatch Finder currently allows mismatch providers to report mismatches to data that is stored in the main part of a statement. In the upcoming deployment, mismatch providers will have the option to report mismatches found within qualifiers, as important data is stored there as well. This change will require mismatch uploaders to adjust their workflow, as we will introduce a new 'type' column to the accepted CSVs. The CSV upload will look as follows:

CSV for a Q42 statement with qualifier, where both the statement and the qualifier are mismatched:

item_id,statement_guid,property_id,wikidata_value,external_value,external_url,type

Q42,Q42$A3B1288B-67A9-4491-A3AA-20F881C292B9,P3373,Q14623673,”Shoshanna Adams”,example.com,statement

Q42,Q42$A3B1288B-67A9-4491-A3AA-20F881C292B9,P1039,Q10943095,”cousin”,example.com,qualifier


CSV for a Q42 statement with qualifier, where only the qualifier is mismatched:

item_id,statement_guid,property_id,wikidata_value,external_value,external_url,type

Q42,Q42$A3B1288B-67A9-4491-A3AA-20F881C292B9,P1039,Q10943095,”cousin”,example.com,qualifier


This new feature is currently being developed under T313467 where you can find more detailed information and to follow the progress of this enhancement. If you have questions or concerns or want to provide feedback, please use the linked Phabbricator ticket or leave us a note at Wikidata talk:Mismatch Finder.


Cheers,
