Which dimensions of narrative are relevant for human judgments of story equivalence?
Bernhard Fisseni, Benedikt Löwe

Abstract:
We present an experimental approach to determining natural dimensions
of story comparison. The results show that untrained test subjects
generally do not privilege structural information. When asked to
justify sameness ratings, they may refer to content, but when asked to
state differences, they mostly refer to style, concrete events,
details and motifs. We conclude that adequate formal models of
narratives must represent such non-structural data.
