The aim of this project, due to begin in January 1982 under the auspices of Grant HR 7829/1 from the SSRC (UK), is to design, evaluate, and debug a computer realization of a generalized phrase structure grammar for a very large fragment of English. The realization will be in a form which is neutral with respect to parsing or generating sentences, and which(More)
GUS is the first of a series of experimental computer systems that we intend to construct as part of a program of research on language understanding. In large measure, these systems will fill the role of periodic progress reports, summarizing what we have learned, assessing the mutual coherence of the various lines of investigation we have been following,(More)
Characterization of vertebrate chemo-orientation strategies over long distances is difficult because it is often not feasible to conduct highly controlled hypothesis-based experiments in natural environments. To overcome the challenge, we couple in-stream behavioral observations of female sea lampreys (Petromyzon marinus) orienting to plumes of a(More)
A novel system combining a trap and pulsed direct current electricity was able to catch up to 75% of tagged invasive sea lamprey Petromyzon marinus in free-flowing streams. Non-target mortality was rare and impacts to non-target migration were minimal; likely because pulsed direct current only needed to be activated at night (7 hours of each day). The(More)
This paper proposes performing natural language generation using genetic algorithms to address two issues: the difficulty in controlling global textual features which arise from a large number of interdependent local decisions, and the difficulty in applying conventional NLG wisdom in domains where the communicative goal lacks sufficient detail. It presents(More)
