Computational Storytelling and Narrative Theory


In collaboration with the Institute for English and American Studies, this project attempts to conceptualize and implement a computational model of story generation, which is informed by narratological theory as well as cognitive modeling.

It approaches this problem starting from a mimetic stance towards fictional characters, that is, describing characters as intentional agents with discernible internal states like beliefs, desires, and affect. This allows investigating how narrative phenomena related to these paper beings can be computationally recreated in a multi-agent simulation system. Based on this internal perspective on narrative, the project also explores how from an external perspective the creative generation of plot can be controlled, and how the quality of the resulting plot can be evaluated, as a function of fictional characters.

The aim is to contribute to research on computational creativity by conceptualizing and implementing an evaluative storytelling system, and to narratology by proposing a generative narrative theory based on several post-structuralist descriptive ones. By using research methods from computer science to address problems from narrative theory this project also explores the use of interdisciplinary research methodology.

Concept Invention Theory


The capacity of combinational creativity—i.e.when novel ideas are produced through unfamiliar combinations of familiar ideas—is difficult to recreate computationally. In particular, it is a hard task for autonomous computational systems to tackle the combinatorial explosion of potential combinations, and to be capable of recognizing the value of newly created ideas (concepts, theories, solutions, etc.), particularly when they are not specifically sought-this is the problem of creative serendipitous behaviour.

In COINVENT we aim to develop a computationally feasible, cognitively-inspired formal model of concept creation, drawing on Fauconnier and Turner's theory of conceptual blending, and grounding it on a sound mathematical theory of concepts.

Concept Formation in Conceptual Spaces


In artificial intelligence, one can distinguish two layers of knowledge representation: Is the symbolic layer, abstract knowledge is represented in a structured, logic-based format, whereas in the subsymbolic layer, perceptual knowledge is stored in a numeric way, e.g., in the form of weights within a neural network. Ultimately, both approaches will have to be combined in order to arrive at a truly integrated system. It is however still unclear how exactly to accomplish this.

The cognitively inspired framework of conceptual spaces proposes to solve this problem by using an intermediate conceptual layer based on geometric representations: One can identify abstract symbols from the symbolic layer with regions in a high-dimensional space whose cognitively meaningful dimensions are based on subsymbolic perceptual processing.

In our lab, we explore this idea by formalizing the conceptual spaces framework in mathematical terms, implementing this formalization, and applying machine learning algorithms to it. By trying to extract meaningful dimensions from data sets, we aim to (partially) automate the construction of conceptual spaces. By grouping points in a conceptual space into regions, we aim to enable artificial systems to automatically discover new concepts based on unlabeled observations.
