11+;;Quote: the heart of meaning representation is the representation of events; events at core of CD (conceptual dependency)
11 ;;Quote: every CD event has an actor, an action, an object acted upon, and a direction of action; invariant across possible descriptions of the event
11 ;;Quote: CD forces you to postulate actors, objects, action and direction for all events; this make explicit what may be implicit in a sentence
11 ;;Quote: slot filling is a major role of CD descriptions, whether for parsing sentences or making inferences; unknown elements from sentence or general knowledge
11 ;;Quote: a CD actor, a concrete object, decides to act upon another concrete object; a rock is a concrete object but not an actor; both are picture producers
12 ;;Quote: a CD action is what an actor does to a concrete object
12 ;;Quote: in 'John went to New York', the CD object is also 'John' because of a rule attached to the verb 'go', i.e., 'John went John to New York'
13 ;;Quote: a crucial part of understanding is knowing what information you need to know; role of slots in CD
13 ;;Quote: in CD, events are represented independent of sentences and words; these representations use predefined schemas with rule governed slots
14 ;;Quote: CD needs a set of meaning primitives to work in the most general way possible without duplicating information
16 ;;Quote: ATRANS is a primitive CD action; its meaning is the set of inference rules that fire because of its presence
17 ;;Quote: CD primitive actions are transfer possession/information/place, speak, ingest, build mental object, grasp, expel, propel, attend, and move
30 ;;Quote: a script gives the appropriate behavior for a standard situation; e.g., asking a waitress for food in a restaurant script
31 ;;Quote: every script includes roles; the actors in a story take on the roles of the script on instantiation; unfilled roles are assumed
33 ;;Quote: in stories without available scripts, we reconstruct the planning process of each character to determine their plans and goals
35 ;;Quote: a planbox is a stereotypical method of attempting a goal; it has preconditions, an action, and a goal; e.g., ASK whose action is MTRANS
37 ;;Quote: the key problem it determining plans is understanding the kinds of goals that people ordinarily pursue
39 ;;Quote: if we identify the theme that a person is operating under, we can predict his pattern of goals; e.g., garabageman collects garbage because of job
