Show answer & explanation
Correct answer: A
Correct matching and brief explanations:
Frames → Record-like structures for grouping closely related knowledge (frames use slots and values to store attributes and default values).
Conceptual dependency → Structures and primitives to represent sentences (conceptual dependency represents meaning using primitives and relations).
Associative (semantic) networks → Pictorial representation of objects, their attributes and relationships (nodes and labeled links).
Scripts → Descriptions of stereotyped real-world events (ordered sequences of actions with roles and typical participants).
Final code mapping: (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii).
Key reasoning:
Frames group related attributes using a slot/value record structure, so they match the record-like description.
Conceptual dependency focuses on representing sentence meaning with a fixed set of primitives and relations, matching the sentence-structure description.
Associative/semantic networks are naturally drawn as pictorial graphs showing objects and relationships.
Scripts encode typical event sequences and roles, matching the stereotyped events description.
