Usage-based Construction Learning
For my doctoral research I built a model of the acquisition of early multiword and grammatical constructions, with special attention to relational form-meaning mappings. The main components of the approach taken in this work are:
- rich situational representations that approximate the conceptual world available to a language-learning toddler;
- a computationally precise grammatical formalism for representing linguistic constructions pairing these rich meanings with elements of form;
- and a usage-based approach to learning such constructions from a corpus of utterance-situation pairs, based on minimum description length.
Together these representations, both conceptual and constructional,
support a tractable usage-based model of child language acquisition,
with a central role for meaning as it is communicated in context.
