R.I.P. Roger Carl Schank! († January 29, 2023)
The central focus of Schank’s theory has been
the structure of knowledge, especially in the context
of language understanding. Schank (1975) outlined
contextual dependency theory which deals with the
representation of meaning in sentences. Building upon
this framework, Schank & Abelson (1977) introduced
the concepts of scripts, plans and themes to handle
**story-level** understanding. Later work (e.g., Schank,
1982,1986) elaborated the theory to encompass other
aspects of cognition.
