Script

In symbolic natural language processing (NLP) a script is repre­sented as a causal chain of events with a number of open roles (Culling­ ford 1978; Dejong 1979; Dyer et al. 1987; Schank and Abelson 1977; table 2.1). Different variations of the script are called Tracks. For exam­ple, there is a fancy-restaurant track, fast-food track, and a coffee-shop track for the restaurant script, each with slightly different events.
