From the Interactive Media & Games Seminar Series; Marilyn Walker, Professor of Computer Science and head of the Natural Language and Dialogue Systems Lab at the University of California, Santa Cruz, discusses her work on storytelling agents who retell existing stories, such as personal narratives posted on weblogs. She describes her method for representing the deep semantic structure of these stories, and how these representations allow us to produce thousands of different retellings of the same story, using narratologically-inspired verbal parameters and personality-based nonverbal parameters.
