Although a large number of natural language database interfaces have been developed, there have been few empirical studies of their practical usefulness. This paper presents the design and results of a field evaluation of a natural language system-NLS-used for data retrieval.
Technical feasibility and promise of practical use for querying databases in natural 1 anguage (for example, English) has been demonstrated by a large number of experimental systems, and the commercial availability of at 1 east one such system. Yet natural 1 anguage continues to be the most controversi al among the 1 anguage interfaces that have been(More)
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(More)
One apparent benefit Web use provides individuals is the opportunity to seek and find vast amounts of information on virtually any subject. By having more information available, it is reasonable to believe that a user would be able to generate more ideas than he/she would without Web support. Given that the Web is being used more frequently for information(More)
Most evaluations of computer languages have used laboratory experiments as the basis of their research design [ll. While much has been learned from these studies, they all suffer from a number of defects including unrealistic subject populations, a narrow focus, a lack of strength of the independent variables and artificiality of the experimental situation.(More)
aspects of biological control of plant pathogens, and the programme and local arrangements were ably handled by Dr. Gindrat of the Federal Research Station, Nyon. After the stage had been set by a long illustrated opening address, spoken slowly in beautifully constructed French by Professor Viennot-Bourgin, the discussions included a variety of approaches(More)
