“…Automatic story generation has a long history, with early work based primarily on hand-written rules (Klein et al, 1973;Meehan, 1977;Dehn, 1981;Turner, 1993). Subsequent methods were based on planning from artificial intelligence (Theune et al, 2003;Oinonen et al, 2006;Riedl and Young, 2010) and, more recently, data-driven methods have been developed (McIntyre and Lap ata, 2010;Elson, 2012;Daza et al, 2016;Roemmele and Gordon, 2015;Clark et al, 2018a;Martin et al, 2018;Fan et al, 2018b;Yao et al, 2019;Fan et al, 2019). In concurrent work, Gupta et al (2019) also propose methods to generate more diverse and interesting story endings, albeit without control variables.…”
