Hey,

This is the 19th weekly update from revision scoring team that we have sent
to this mailing list.

Deployments:

   - We deployed a set of new models to ORES that reduce our memory usage
   and slightly increase fitness. [1]  These models were discussed in an email
   to the "ai" mailing list. [2]


   - We also completed a major quarterly goal.  The ORES review tool is now
   deployed as a beta feature on 8 wikis! [3]  This came with some quick fixes
   to fix some confusion and usability issues. [4]  The beta feature is now
   available on English, Polish, Portuguese, Russian, Dutch, Persian and
   Turkish Wikipedias as well as Wikidata.


New development:

   - We discussed and came to a rough consensus about how to integrate ORES
   into api.php. [5]


   - We deployed a new edit quality campaign on English Wikipedia to gather
   more data for training ORES. [6, 7]


   - We added a specific set of user groups to the ORES models for Turkish
   Wikipedia and saw an increase in model fitness. [8]


Maintenance and robustness:

   - We fixed bugs in our maintenance scripts for purging old model
   versions [9, 10]


   - We switch to using our production models on the beta labs cluster so
   now we can catch vandalism there too (and know that the models actually
   work) [11]


   - We improved the error messages reported from Wiki Labels so that the
   actual error appears when the API responds with non-200 HTTP status [12]
