"The GRIOT computational narrative system utilizes techniques suitable for representing meaning and expression such as the thoughts in the paragraph above. GRIOT is a computer program developed to implement systems that output narratives in response to user input."
"In algebraic semiotics the structure of complex signs, including multimedia signs (e.g., a film with closed captioning), and the blending of such structures are described using semiotic systems (also called sign systems) and semiotic morphisms (mappings between sign systems).
This does not imply a belief that meaning can be reduced to mathematical formalization; on the contrary, the underlying theories in cognitive linguistics assert that meaning is considered to be contextual and dynamic, and has a basis in embodied human experience. This means that meaning is "actively constructed by staggeringly complex mental operations" such as conceptual blending (Ibid., 8). Furthermore, meaning depends upon the fact that humans exist "in a world that is inseparable from our bodies, our language, and our social history" (Varela, Thompson and Rosch 1991). These underlying assumptions about the nature of meaning and the use of formalization are some of the characteristics that distinguish GRIOT from other work in poetry and narrative generation."
"My longer-term project involves using this technical and theoretical framework as a basis for creating further computational narrative artworks where in addition to textual input, users can interact with graphical or gamelike interfaces. This user interaction will still drive the generation of new metaphors and concepts, but along with text will also result in blends of graphical and/or audio media."
