This dataset contains the entire corpus of feedback submitted on the English, French and German Wikipedia during the Article Feedback v.5 pilot (AFT). [1] The Wikimedia Foundation ran the Article Feedback pilot for a year between March 2013 and March 2014. During the pilot, 1,549,842 feedback messages were collected across the three languages.

All feedback messages and their metadata (as described in this schema [2]) are available in this dataset, with the exception of messages that have been oversighted and/or deleted by the end of the pilot.
The corpus is released [3] under the following license:

• CC BY SA 3.0 for feedback messages

• CC0 for the associated metadata

Results from the pilot are discussed in: Halfaker, A., Keyes, O. and Taraborelli, D (2013). Making peripheral participation legitimate: Reader engagement experiments in Wikipedia. CSCW ’13 Proceedings of the 2013 Conference on Computer Supported Cooperative Work [4][5]
