Watchlist Expiry: Data on Current Number of Watched Items
Closed, ResolvedPublic

Description

As a product manager, I want to know how many items are currently in the watchlist, so that I can compare the original baseline (before implementation of the feature) to afterward (i.e., after watchlist expiry is available).

Background: We are hoping that the implementation of watchlist expiry will eventually decrease the total number of items in the general watchlist table. Consequently, we would like to compare the number of items watched right before the implementation of the tool to the number of items watched after the implementation. We would also like to see the number of watched items that are added over the course of a month may potentially increase/decrease with the implementation of watchlist expiry.

Acceptance Criteria:

  • Determine the total number of items watched on English Wikipedia, German Wikipedia, Japanese Wikipedia, and Wikidata before the implementation of the watchlist expiry over one month period (i.e,, we want to see the total growth)
  • Determine the total number of items watched on English Wikipedia, German Wikipedia, Japanese Wikipedia, and Wikidata after the implementation of the watchlist expiry over one month period (i.e,, we want to see the total growth)

@jwang We can talk about this during our next meeting. Thanks!

LGoto moved this task from Triage to Needs Investigation on the Product-Analytics board.

@ifried, as we discussed, you want to analyze watchlist on top 10 wikis. I am here to confirm the wiki list with you.

The top 10 wikis based on the wiki segmentation’s size ranking( geometric mean of monthly active editors and monthly unique devices):
English wikipedia, Spanish wiki, German wiki, Japanese wiki, French wiki, Russian wiki, wiki commons, Italian wiki, Chinese wiki, Portuguese wiki
(source https://phabricator.wikimedia.org/T237129 , data in 2019)

Given Chinese wiki was blocked since 2019, we can exclude Chinese wiki from the list. Combining your original request list (English Wikipedia, German Wikipedia, Japanese Wikipedia, and Wikidata), the wikis we focus on will be:
English wikipedia, Spanish wiki, German wiki, Japanese wiki, French wiki, Russian wiki, wiki commons, Italian wiki, Portuguese wiki, wikidata.

Let me know if you want to include or exclude some wikis here.

Thanks,
Jennifer

@Ilana, the average of 2 month is ready. Please review.

Thanks,
Jennifer

Thank you so much, @jwang! This information will help us have an understanding of the average number of pages that are watched per month, which will provide a baseline for comparison after implementing the watchlist expiry feature. Much appreciated!

The task is done and reviewed. So close it.
