Abstract

About fifteen years of active research in natural language question-answering systems has provided reasonably concise and elegant formulations of computational semantics for understanding English sentences and questions about various microworlds. These include the Woods Lunar Data Base, the Winograd world of a pictured hand and blocks, the Heidorn world of a fueling station, the Hendrix, Slocum, Thompson world of transactions, John Seely Brown's power circuit and Schank's sketches of motivated humans. (See Woods et al 1972, Winograd 1972, Hendrix et al 1973, Heidorn 1972, Schank 1975 and Brown et al 1974.) In each of these worlds, a natural language processor is able to understand an ordinary subset of English and use it conversationally to accept data and to respond to commands and questions.
