SC2 Computational Models of How People Make Stories

Description

Humans are very good at perceiving events that have happened in the world and synthesizing them as stories that are easy to understand and interesting to follow. Indeed, such stories are one of the fundamental currencies for knowledge exchange in our culture, from literary master pieces to ordinary anecdotes in daily conversation. We are also capable of inventing new stories to act as vehicles of communication or tools for various goals, from learning to entertainment. Yet computers, which are currently our main recording devices, do not store knowledge in the form of narrative. Some parts of the human story making ability have been long-standing goals of AI -- such as the generation of simple stories -- and the fuller picture of how this ability operates has recently become the focus of considerable effort in the fields of narratology and computational creativity. These efforts are particularly relevant because unless we find a way to build computational models of the process of how humans construct stories, we face a future where our narrative understanding of the world will be side-lined by less natural representations that are easier to compute for machines.
The course addresses existing efforts at modelling the human story making ability from four different perspectives. First, it reviews existing theoretical efforts to understand stories in the light of how they might be understood computationally. Second, it visits some of the attempts to develop systems that can invent stories. Third, it describes ongoing efforts to compose stories automatically from conceptually described facts. Finally, it presents some of the insights into how human cognition is applied to the task, with a view to identifying clues that might help computational modelling.

1. Stories: what are they and/or why are they important to people?
2. Inventing stories: coming up with new stories to tell
3. Composing stories: learning to tell what you know as good stories
4. The process of story making: (guessing) how people go about doing it

Objectives

The goal of the course is threefold:
1. to understand the importance of having computational models of story making
2. to explore the gaps between the narratological and the computational views of the task
3. to review existing efforts and outstanding challenges in the field
