Automated Storytelling via Causal, Commonsense Plot Ordering
Automated story plot generation is the task of generating a coherent sequence
of plot events. Causal relations between plot events are believed to increase
the perception of story and plot coherence. In this work, we introduce the
concept of soft causal relations as causal relations inferred from commonsense
reasoning. We demonstrate C2PO, an approach to narrative generation that
operationalizes this concept through Causal, Commonsense Plot Ordering. Using
human-participant protocols, we evaluate our system against baseline systems
with different commonsense reasoning reasoning and inductive biases to
determine the role of soft causal relations in perceived story quality. Through
these studies we also probe the interplay of how changes in commonsense norms
across storytelling genres affect perceptions of story quality.Comment: AAAI-21 Camera Ready Versio
Bringing Stories Alive: Generating Interactive Fiction Worlds
World building forms the foundation of any task that requires narrative
intelligence. In this work, we focus on procedurally generating interactive
fiction worlds---text-based worlds that players "see" and "talk to" using
natural language. Generating these worlds requires referencing everyday and
thematic commonsense priors in addition to being semantically consistent,
interesting, and coherent throughout. Using existing story plots as
inspiration, we present a method that first extracts a partial knowledge graph
encoding basic information regarding world structure such as locations and
objects. This knowledge graph is then automatically completed utilizing
thematic knowledge and used to guide a neural language generation model that
fleshes out the rest of the world. We perform human participant-based
evaluations, testing our neural model's ability to extract and fill-in a
knowledge graph and to generate language conditioned on it against rule-based
and human-made baselines. Our code is available at
