Usage-based learning of grammatical categories

Boekbijdrage - Boekhoofdstuk Conferentiebijdrage

Human languages use a wide range of grammatical categories
to constrain which words or phrases can fill certain slots in grammatical
patterns and to express additional meanings, such as tense or aspect,
through morpho-syntactic means. These grammatical categories, which
are most often language-specific and changing over time, are difficult to
define and learn. This paper raises the question how these categories can
be acquired and where they have come from. We explore a usage-based
approach. This means that categories and grammatical constructions are
selected and aligned by their success in language interactions. We report
on a multi-agent experiment in which agents are endowed with mechanisms for understanding and producing utterances as well as mechanisms
for expanding their inventories using a meta-level learning process based
on pro- and anti-unification. We show that a categorial type network
which has scores based on the success in a language interaction leads to
the spontaneous formation of grammatical categories in tandem with the
formation of grammatical patterns.
