Next week, the Purple Blurb series offers a second special summer talk by a leading researcher in creative text generation. Rafael Pérez y Pérez will speak on …
MEXICA: A Computer Model for Plot Generation of Prehispanic Stories
MEXICA is a computer model that generates plots for short stories about the Mexicas, the old inhabitants of what today is México City, based on the engagement-reflection cognitive account of writing. During engagement MEXICA generates material guided by content and rhetorical constraints, avoiding the use of explicit characters’ goals or story-structures. During reflection the system breaks impasses, evaluates the novelty and interestingness of the story in progress and verifies that coherence requirements are satisfied. In this talk I will explain the main characteristics of the system, I will show how emotions are employed to progress a story in a coherent way and generate novel situations, and how the dramatic tension of the story in progress might be employed to evaluate its interestingness. I will present results showing how story generation is affected by various model parameters and I will compare MEXICA with other story-generators programs. Finally, I will mention how we are employing MEXICA as starting point for new research projects.
Pérez y Pérez will speak on Wednesday July 15, 6pm-7pm, at MIT in room 14E-310. This is in the same location as Pablo Gervás’s talk in May, and just one more floor up the stairs from the Trope Tank, where other Purple Blurb events were located. The talk is (as with all Purple Blurb presentations) open to the public.
Rafael Pérez y Pérez earned a BSc. in Electronics and Computers at Universidad Iberoamericana in México City, a MSc. in Knowledge Based Systems and a DPhil. in Artificial Intelligence at Sussex University in England. His research has focused on computer models of creativity. He and his students have developed programs that write short stories, compose music, and solve geometry problems, among other things. In 2006 he organised the Mexican Creativity, Cognition and Computers research group (MCCC) which aims to gather together a multidisciplinary group of researchers and students interested in computational creativity. He has published different papers in the area and has participated as a PC member and co-chair in international events related to computational creativity. Currently he is a researcher and lecturer at The Autonomous Metropolitan University (Universidad Autónoma Metropolitana or UAM) in México City and an invited Lecturer in the MSc and PhD programs in Computer Science at The National Autonomous University of México (Universidad Nacional Autónoma de México or UNAM).
