FinLFQA: Evaluating Attributed Text Generation of LLMs in Financial Long-Form Question Answering

EMNLP 2025

Large Language Models (LLMs) frequently hallucinate to long-form questions, producing plausible yet factually incorrect answers. A common mitigation strategy is to provide attribution to LLM outputs. However, existing benchmarks primarily focus on simple attribution that retrieves supporting textual
