Advances in temporal databases make it increasingly easier to store time-dependent information, creating a need for facilities that will help end-users access this information. In the context of natural language interaction, significant effort has been devoted to interfaces that allow database queries to be formulated in natural language. Most of the existing interfaces, however, do not support adequately the notion of time. Drawing upon tense and aspect theories, temporal logics, and temporal databases, this cross-discipline book examines relevant issues from the three areas, developing a unified theoretical framework that can be used to build natural language interfaces to temporal databases. The framework features an HPSG mapping from English to a formally defined meaning representation language, and a corresponding mapping to a temporal extension of the SQL database language. The book is accompanied by a freely available prototype interface, built according to the framework, and implemented using Prolog and ALE. This is the first in-depth exploration of the notion of time in natural language database interfaces. It will be particularly interesting to researchers working on natural language interaction, tense and aspect, HPSG, temporal logics, and temporal databases, especially those who wish to learn about time-related issues in other disciplines.

Quotes

“This book is explicit and provides a useful resource for researchers and developers of natural language interfaces and temporal databases. The framework addresses difficult problems involved in making natural language queries to temporal databases possible, and together with its prototype interface, it constitutes a foundation from which more complex interfaces may be developed and the value of representing event structure in temporal databases may be explored.”

“The book is true to its name; it explores the issues of time, tense and aspect, keeping NLIDBs [Natural Language Interfaces to Data Bases] as an empirical grounding for an otherwise theoretical discussion. However, the discussion in the book is leading the state of the art in NLIDBs towards more empirical and less exploratory work. Moreover, the book contains clear place-holders for researching issues such as evaluation and cooperative response generation. On that behalf, the book provides a necessary milestone on that worthy path.”
