This dataset contains sentences from Reddit.
Each sentence is scored according to how similar it was to a spoken (dialogue_prob) or written (forum_prob) communication.

For details of how we scored the sentences, see our [EMNLP 2025 paper](https://aclanthology.org/2025.findings-emnlp.826/). 
However, we did not make use of this dataset in the results reported in this paper. 
Our early experiments showed no gains versus using the much smaller C4 and Subtitle training sets.
