Conceptual Dependency

Conceptual Dependency is a theory of Roger Schank that combines several ideas:

  1. Definition of verbs in terms of underlying concepts called primitive acts (14 or so).
  2. Deep case relations between primitive acts and objects.
  3. Semantic network representation of these structures.

The primitive acts include:

TRANS Transfer (e.g. ``give'')
INGEST Ingest into the body
EXPEL Expel from the body
ATRANS Abstract transfer (e.g. ownership)
MOVE Move a body part
GRASP Grasp an object
PROPEL Propel (e.g. throw) an object
PTRANS Physical transfer
MTRANS Mental transfer
CONC Conceptualize
ATTEND Direct sensory organ to observe
