This is the 26th and 27th weekly update from revision scoring team that we
have sent to this mailing list. We forgot to send the update for last week!

Last week, we were featured in Research's quarterly review. In the last 3
months, we achieved our goals to expand the ORES extension to 6 wikis (we
made it to 8!) and to release datasets of article quality predictions. The
minutes from the quarterly review are not yet online, but once they are,
you'll be able to see them at [1].

Maintenance and robustness:

  • We discussed and decided on a set of strategies for handling goodfaith/naive DOS attacks on ORES[2]
  • We fixed an i18n issue in Wiki Labels[3]
  • We updated the article quality models (wikiclass/wp10) to use revscoring 1.3.0[4]
  • We investigated and solved a memory leak in our pre-caching utility[5]
  • We configured celery to send its logs to a place where we can read them for easier debugging[6]
  • We deployed a set of schema changes to constrain the ORES Review Tools database appropriately[7]
  • Also worth noting is that the services cluster (SCB) has been expanded[8]. ORES has now doubled in capacity


  • We discussed how to make the historical article quality dataset available via quarry[8]. Regretfully, it seems that we'll not be able to do that for at least a couple of months.

New development

  • We've implemented embedding of machine-readable scores in a JS variable on-wiki[9]. This will make it easier for tool developers to experiment with new ways of displaying Special:RecentChanges more easily. It's also a necessary precondition for adding color-based signaling of ORES' confidence about an edit.
