- Abstract
- Many tasks in language analysis are described as the maximally economic
mapping of one level of linguistic representation onto another such level. Over the
past decade, many different machine-learning strategies have been developed to
automatically induce such mappings directly from data. In this paper, we contend
that the way most learning algorithms have been applied to problems of language
analysis reflects a strong bias towards a compositional (or biunique) model of interlevel
mapping. Although this is justified in some cases, we contend that biunique
inter-level mapping is not a jack of all trades. A model of analogical learning,
based on a paradigmatic reanalysis of memorized data, is presented here. The
methodological pros and cons of this approach are discussed in relation to a
number of germane linguistic issues and illustrated in the context of three case
studies: word pronunciation, word analysis, and word sense disambiguation. The
evidence produced here seems to suggest that the brain is not designed to carry out
the logically simplest and maximally economic way of relating form and function
in language. Rather we propose a radical shift of emphasis in language learning
from syntagmatic inter-level mapping to paradigmatically-constrained intra-level
mapping. (literal)
