Constructions emerging : a usage-based model of the acquisition of grammar
Full text link
This dissertation is concerned with the development of grammar.
Starting from a
usage-based perspective, which holds that children use domain-general
learning mechanisms to acquire the grammatical patterns of their mother
tongue, Beekhuizen shows how to operationalize various concepts from
this tradition in a computational
model. In order to arrive at a sound set of assumptions, Beekhuizen
compares and criticizes various earlier usage-based modeling approaches
and scrutinizes the concepts of a usage-based theory of language
acquisition from the perspective of a
computational modeler. As the model should be able to produce utterances
on the basis of a meaning to be expressed, as well as to interpret
utterances, the availability of meaning from the situational context is
studied empirically. The resulting model, the Syntagmatic-Paradigmatic
Learner, simulates an increasing ability to understand utterances on the
basis of a grammar of constructions, as well as to produce utterances
on the basis of this grammar. Several developmental effects are
simulated and the internal states of the model are carefully examined.NWO (grant 322.70.001)Language Use in Past and Presen
