Originally published in 1978, The Process of Question Answering
examines a phenomenon that relies on many realms of human
cognition: language comprehension, memory retrieval, and language
generation. Problems in computational question answering assume a
new perspective when question answering is viewed as a problem in
natural language processing. A theory of human question answering
must necessarily entail a theory of human memory organization and
theories of the cognitive processes that access and manipulate
information in memory. This book describes question answering as a
particular task in information processing. The theoretical models
described here have been built on a formulation of general theories
in natural language processing: theories about language that were
developed without the specific problem of question answering in
mind. By requiring programmers to be concerned with the precise
form of information in memory, and the precise operations
manipulating that information, they can uncover significant
problems that would otherwise be overlooked. An early insight into
artificial intelligence, today this reissue can be enjoyed in its
historical context.
