“…Early approaches to automatic story generation relied on graph-based planning and hand-crafted rules to structure narratives (Meehan, 1977;Callaway and Lester, 2002;Riedl and Young, 2004;Li et al, 2013). More recent works generate stories by finetuning on large-scale PLMs (See et al, 2019) to improve its fluency and incorporating structured knowledge such as planned events Fang et al, 2021;Li et al, 2022), summaries (Yao et al, 2019Tan et al, 2021;Sun et al, 2020), and external knowledge (Guan et al, 2019;Xu et al, 2020b;Guan et al, 2020) to enhance its coherence and consistency. Our story generation models are also finetuned on the large-scale PLMs to generate text following the given summaries.…”
