“…Factuality Evaluation Recent advances in text summarization have presented models and systems that are capable of generating increasingly fluent, controllable, and informative summaries of documents (Liu and Lapata, 2019;Meng et al, 2022;Tang et al, 2022;Goldsack et al, 2022;Peng et al, 2021;Aharoni et al, 2023;Liu et al, 2022d;Rothe et al, 2021;Bhattacharjee et al, 2023;Chen et al, 2023b;He et al, 2023;Chen et al, 2023a). However, they suffer from hallucination and might not be factually faithful towards the source document (Cao et al, 2018;Balachandran et al, 2022;Tang et al, 2023;Liu et al, 2023a;Luo et al, 2023), leading to increased research in factuality evaluation.…”
