This classifier is trained on LLM responses designed to capture a model refuting a false claim.
They're prompt results of OpenAI gpt-3.5-turbo run on June 1 2023. Prompts are constructed by prepending "Explain why" to claims made in the True-False dataset provided alongside The Internal State of an LLM Knows When its Lying. Only the first sentence of the response is included (from nltk.sent_tokenize). The original labels are used, where 0 corresponds to a false claim. That is, the 0 labels should be almost all refutations. Spurious and missing refutations were removed by hand, corresponding to about 10% of the data. This were caused by either an incorrect model assertion, or errors in the source data.
