Community Wishlist Survey 2021/Wikidata/Duplicates and merge candidates

Random proposal ►◄ Wikidata  The survey has concluded. Here are the results!

Duplicates and merge candidates

• Problem: There is an increasing number of items that are empty or possible duplicates
• Who would benefit: Wikidata editors
• Proposed solution: Improve on prior art like Projectmerge to detect duplicates not only by labels but by comparing properties and links with other items; migrate the WD:DNM do not merge lists to something more usable (example suggested in the discussion page, migrate to P1889 statements
• More comments:
• Phabricator tickets:

Discussion

• Removed the Phabricator task as it's not relevant. --Matěj Suchánek (talk) 15:54, 20 November 2020 (UTC)
• @Sabas88: Thanks for your proposal. Is there code for the mentioned projects that we can take a look at? We'd like to have a better understanding on how the projects detect duplicates. Thanks again! Harumi Monroy 19:35, 23 November 2020 (UTC)

  Sorry I can't find it... Help:Merge has a list of tools but I didn't see a relevant git repository --Sabas88 (talk) 12:45, 25 November 2020 (UTC)

• A good idea. Improve on existing tools, to be able to better predict if two items are duplicate. Simplistic example: same name, different description, but both populated places (or similar property, city, village) with a very similar geographic location (within a radius of 2 km one from the other). --FocalPoint (talk) 05:58, 24 November 2020 (UTC)

  Or if not same name, perhaps with some other String Metric and comparing properties..--Sabas88 (talk) 12:45, 25 November 2020 (UTC)

• Neutral I support the improvements to the merge tools, but for me the most needed would be creation of Merge tool that allows "Unmerge" option as I see a lot of bad merges done with easy to use merge tools used by users with very little experience. This proposal does not mentions any Unmerge options. --Jarekt (talk) 15:29, 12 December 2020 (UTC)
