The Process of Question Answering: A Computer Simulation of Cognition

This book describes question answering as a particular task in information processing. The theoretical models described here have been built on a foundation 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.
