A Straightforward Approach to Narratologically Grounded Character Identification (2020.coling-main)
Copied to clipboard
| Challenge: | Existing definitions of character are based on simplified or implicit definitions that do not capture essential distinctions between characters and other referents in narratives. |
| Approach: | They propose a narratologically grounded definition of character that is based on clear narrological principles and annotated 170 narrative texts. |
| Outcome: | The proposed definition of character is based on clear narratological principles and can be reliably annotated (0.78 Cohen’s ). |
Inducing Stereotypical Character Roles from Plot Structure (2021.emnlp-main)
Copied to clipboard
| Challenge: | Stereotypical character roles are important aids to narrative understanding and are often referred to as archetypes or dramatis personae. |
| Approach: | They propose an unsupervised method for learning stereotypical roles given only structural plot information using Vladimir Propp’s structural theory of Russian folktales. |
| Outcome: | The proposed method induces six out of seven of Vladimir Propp’s dramatis personae with F1 measures of up to 0.70 (0.58 average), with an additional category for minor characters. |
