Grammar development
Semantic bootstrapping
-
syntactic categories: nouns = person/things, verbs = actions
semantic - syntactic correspondence: linking rules relating syntactic and semantic categories: agent = subjects, patients = objects
learn meanings, categories them into semantic categories, use thematic roles of agent and patient to infer syntactic structure
we use knowledge of word meaning to allow us to assume that words of the same general meanings will occupy the same slot in a sentence
agent: noun and subject, action: verb, patient: noun and object
