 In the paper, we document various types of bias that are present in the quality ratings from the QuRater model (biases related to domains, topics, social roles, regions and languages - see Section 6 of the paper).
 Hence, be aware that data selection with QuRating could have unintended and harmful effects on the language model that is being trained. 
 We strongly recommend a comprehensive evaluation of the language model for these and other types of bias, particularly before real-world deployment. 
-We hope that releasing the data/models can facilitate future research aimed at uncovering and mitigating such biases.
