Abstract
Distributed neural networks have been very successful in
modeling isolated cognitive phenomena, but complex high-level
behavior has been amenable only to symbolic artificial intelligence
techniques. Aiming to bridge this gap, this book describes
DISCERN, a complete natural language processing system implemented
entirely at the subsymbolic level. In DISCERN, distributed neural
network models of parsing, generating, reasoning, lexical
processing and episodic memory are integrated into a single system
that learns to read, paraphrase, and answer questions about
stereotypical narratives. Using DISCERN as an example, a general
approach to building high-level cognitive models from distributed
neural networks is introduced, and the special properties of such
networks are shown to provide insight into human performance. In
this approach, connectionist networks are not only plausible models
of isolated cognitive phenomena, but also sufficient constituents
for generating complex, high-level behavior.
Keywords
computational modeling, connectionism, distributed neural
networks, episodic memory, lexicon, natural language processing,
scripts.
