This is a study of how children acquire language and how this
affects language change over generations. Written by an
international team of experts, the volume proceeds from the basis
that we can not only address the language faculty per se within the
framework of evolutionary theory, but also the origins and
subsequent development of languages themselves; languages evolve
via cultural rather than biological transmission on a historical
rather than genetic timescale. The book is distinctive in utilizing
computational simulation and modelling to help ensure the theories
constructed are complete and precise. Drawing on a wide range of
examples, the book covers the why and how of specific syntactic
universals; the nature of syntactic change; the language-learning
mechanisms required to acquire an existing linguistic system
accurately and to impose further structure on an emerging system;
and the evolution of language(s) in relation to this learning
mechanism.
The lexicon is now a major focus of research in computational
linguistics and natural language processing (NLP), as more
linguistic theories concentrate on the lexicon and as the
acquisition of an adequate vocabulary has become the chief
bottleneck in developing practical NLP systems. This collection
describes techniques of lexical representation within a
unification-based framework and their linguistic application,
concentrating on the issue of structuring the lexicon using
inheritance and defaults. Topics covered include typed feature
structures, default unification, lexical rules, multiple
inheritance and non-monotonic reasoning. The contributions describe
both theoretical results and implemented languages and systems,
including DATR, the Stuttgart TFS and ISSCO's ELU. This book arose
out of a workshop on default inheritance in the lexicon organized
as a part of the Esprit ACQUILEX project on computational
lexicography. Besides the contributed papers mentioned above, it
contains a detailed description of the ACQUILEX lexical knowledge
base (LKB) system and its use in the representation of lexicons
extracted semi-automatically from machine-readable dictionaries.
