This is the 20th weekly update from revision scoring team that we have sent
to this mailing list.

New development:

  • We implemented the basic functionality for handling bag of words and other types of abstract feature vectors in revscoring. [1] This required some changes to some dependencies as well. [2]
  • We extended the user-group related features to include more of the dominant groups outside of English Wikipedia [3] and incremented the models that changed substantially [4]


  • We extended the documentation at mw:Extension:ORES to make it easier for new developers to work with us. [5]


  • We discussed the teams resourcing needs (hardware, engineering, and community liaison support) with Wes Moran. [6]

Maintenance and robustness:

  • We addressed a variety of issues around caching and how the ORES extension loads new data
  • ORES now returns headers that will disable secondary caching. [7]
  • Our maintenance scripts will circumvent caches that do not listen to no-cache headers. [8, 9]
  • We fixed an issue where the ORES review tool would duplicate items in Special:RecentChanges. [10]
  • We standardized the extraction pattern for the enwiktionary model so that it looks similar to other models. [11]
