The PAN Wikipedia Quality Flaw Corpus 2012, PAN-WQF-12, provides human-labeled English Wikipedia articles that contain specific quality flaws.
The corpus is intended to train and evaluate automated approaches for the prediction of quality flaws in Wikipedia; for more information, refer to Anderka et al. (2012).
A subset of the corpus has been used in the 1st Competition on Quality Flaw Prediction in Wikipedia, held in conjunction with the PAN 2012 evaluation lab at the CLEF 2012 conference. Details about the competition can be found in Anderka and Stein (2012).
