A major problem in constructing a natural-language interface is determining how to encode and use the information needed to bridge these two views. Current natural-language interface systems require extensive efforts by specialists in natural-language processing to p r o v i d e them w i t h the i n f o r m a t i o n they need to do the b r i d g i n g . The systems are, in effect, handtallored to provide access to particular databases.

Transportable Natural-Language Interfaces: Problems and Techniques
I will address the questions posed to the panel from wlthln the context of a project at SRI, TEAM [Grosz, 1982b], that is developing techniques for transportable natural-language interfaces. The goal of transportability is to enable nonspeciallsts to adapt a natural-language processing system for access to an existing conventional database. TEAM is designed to interact with two different kinds ...
متن کاملTransportability and Generality in a Natural-Language Interface System
This paper describes the design of a transportable natural language (NL) interface to databases and the constraints that transportability places on each component of such a system. By a transportable NL system, we mean an NL processing system that is constructed so that a domain expert (rather than an AI or linguistics expert) can move the system to a new application domain. After discussing th...
متن کاملEvaluation and Assessment of a Domain-Independent Natural Language Query System
This paper is a brief description of TEAM, a project whose goal was to design an experimental natural-language interface that could be transported to existing database systems by people who already possessed expertise in their use. In presenting this overview, we have concentrated on those design aspects that were most constrained by the requirements of transportability. 1 A Functional Descript...
متن کاملUser Specification of Syntactic Case Frames in TELI, A Transportable, User-Customized Natural Language Processor
In this paper, we present methods that allow the users of a natural language processor (NLP) to define, inspect, and modify any case frame information associated with the words and phrases known to the system. An implementation of this work forms a critical part of the Transportable English-Language Interface (TELI) system. However, our techniques have enabled customization capabilities largely...
