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]
