Abstract
In this research, we propose a framework to generate human-like question-answer pairs with long or factoid answers automatically and, based on them, automatically evaluate the quality of Retrieval-Augmented Generation (RAG). Our framework can also create datasets that assess hallucination levels of Large Language Models (LLMs) by simulating unanswerable questions. We then apply the framework to create a dataset of question-answer (QA) pairs based on more than 1,000 leaflets about the medical and administrative procedures of a hospital. The dataset was evaluated by hospital specialists, who confirmed that more than 50% of the QA pairs are applicable. Finally, we show that our framework can be used to evaluate LLM performance by using Llama-2-13B fine-tuned in Dutch (Vanroy, 2023) with the generated dataset, and show the method’s use in testing models with regard to answering unanswerable and factoid questions appears promising.- Anthology ID:
