ChatGPT Hallucinates when Attributing Answers
Guido Zuccon, Bevan Koopman, Razia S. Shaik · 2023
Can ChatGPT provide evidence to support its answers? Does the evidence it suggests actually exist and does it really support the answer? We investigate these questions using a collection of domain-specific knowledge-based questions, specifically prompting ChatGPT to provide both an answer and supporting evidence in the form of references to external sources. We also investigate how different prompts impact answers and evidence.
