Boguraev, B., J. Carroll, E. Briscoe, D. Carter and C. Grover (1987) `The derivation of a grammatically-indexed lexicon from the Longman Dictionary of Contemporary English'. In Proceedings of the 25th Annual Meeting of the Association for Computational Linguistics, Stanford, CA. 193-200.
We describe a methodology and associated software system for the construction of a large lexicon from an existing machine-readable (published) dictionary. The lexicon serves as a component of an English morphological and syntactic analyser and contains entries with grammatical definitions compatible with the word and sentence grammar employed by the analyser. We describe a software system with two integrated components. One of these is capable of extracting syntactically rich, theory-neutral lexical templates from a suitable machine-readable source. The second supports interactive and semi-automatic generation and testing of target lexical entries in order to derive a sizable, accurate and consistent lexicon from the source dictionary which contains partial (and occasionally inaccurate) information. Finally, we evaluate the utility of the Longman Dictionary of Contemporary English as a suitable source dictionary for the target lexicon.
