CD Primitives:

• PTRANS: physical transfer of location of an object

  slots for PTRANS:
  

  ACTOR: a HUMAN (or animate obj) that initiates the PTRANS
  OBJECT: a PHYSICAL OBJECT that is PTRANSed
  FROM: a LOCATION at which the PTRANS begins
  TO: a LOCATION at which the PTRANS ends

• ATRANS: abstract transfer of ownership, possession, or control of an object

• MTRANS: mental transfer of information between agents

• MBUILD: mental construction of a thought or new info between agents

• ATTEND: act of focusing attention of a sense organ toward an object

• GRASP: grasping of an object by an actor for manipulation

• PROPEL: applicaton of physical force to an object

• MOVE: movement of a body part of an agent by that agent

• INGEST: taking in of an object (food, air, water...) by an animal

• EXPEL: expulsion of an object by an animal

• SPEAK: act of producing sound, including non-communicative sounds

Scripts:

1. John went to Duff's for dinner last night.
2. He ordered wings.
3. When he paid for them, he noticed that he was running out of money.
4. He hurried home, since it had started to rain.

QUESTION: Did John eat dinner last night?

SCRIPT        Restaurant

ROLES        C        customer
                    W        waiter

PROPS        F        food

LOC'N        R        restaurant

SCENES:

1.       C      PTRANS      C      to      R
2.       C       ATTEND       eyes       to       menu
3.       C       MTRANS       "I       want       F"       to       W
4.       W       PTRANS       F       to       C
5.       C       INGEST       F
6.       W       PTRANS       bill       to       C
7.       C       PTRANS       money       to       R
8.       C       PTRANS       C       from       R

Processing:

(1) matches (unifies with) (a), where C:=John, R:=Duff's

(2) matches (c)

So, infer (b)

(3) matches (g)

So, infer (d)-(f)

So, ANSWER = Yes [(e) = John ate wings]
