Title: The fourteen primitive actions and their inferences.
Author: Schank, Roger C.
Date: March 1973
Abstract: In order to represent the conceptual information underlying a
natural language sentence, a conceptual structure has been
established that uses the basic actor-action-object
framework. It was the intent that these structures have only
one representation for one meaning, regardless of the
semantic form of the sentence being represented. Actions were
reduced to their basic parts so as to effect this. It was
found that only fourteen basic actions were needed as
building blocks by which all verbs can be represented. Each
of these actions has a set of actions or states which can be
inferred when they are present.
