Webis ChangeMyView Corpus 2020 (Webis-CMV-20)

Al-Khatib, Khalid; Völske, Michael; Syed, Shahbaz; Kolyada, Nikolay; Stein, Benno

The Webis-CMV-20 dataset comprises all available posts and comments in the ChangeMyView subreddit from the foundation of the subreddit in 2005, until September 2017. From these, we have derived two sub-datasets for the tasks of persuasiveness prediction, and opinion malleability prediction. In addition, the corpus comprises historical posts by CMV authors, and derived personal characteristics.
