Syntax – thought that grammar is all you need to make it all work. This is wrong you need to also consider semantics.
Conceptual Dependencies
ATRANS – Abstract transfer (give)
PTRANS – Physical transfer (go)
MTRANS – Mental transfer (tell)
P= Past tense PP = object or picture producer
0 = Object case relation AA = Action modifier (aider)
R = Recipients Act = Action
PA = Picture modifier (aider)
Attribute grammar
How can conceptual dependencies facilitate reasoning?
- Fewer inference rules.
- Many inferences are contained in the representation
- Initial representation of the sentence will have holes. Plugging holes serves as focusing a subject for future sentences.
Argument Against
- Long time to decompose knowledge into primitive actions
- Conceptual dependencies are good for representing, this may not be good for all kinds of knowledge.
