Slider change database
Each entry is of the form < update_id, contributor, video_1, video_2, order, quality_criterion, confidence, new_value, context, duration_ms, timestamp >. Such parameters are defined in the Tournesol main database wiki page.
If the contributors consents, any slider change in the rating page, inconsistency page and disagreement page is saved in the slider change database. The value context records on which page the slider change occurred.
