We describe a formal framework for interpretation of words and compounds in a discourse context which integrates a symbolic lexicon/grammar, word-sense probabilities, and a pragmatic component. The approach is motivated by the need to handle productive word use. In this paper, we concentrate on compound nominals. We discuss the inadequacies of approaches which consider compound interpretation as either wholly lexico-grammatical or wholly pragmatic, and provide an alternative integrated account. . | Integrating Symbolic and Statistical Representations The Lexicon Pragmatics Interface Ann Copestake Center for the Study of Language and Information Stanford University Ventura Hall Stanford CA 94305 USA aacflcsli.stanford.edu Abstract We describe a formal framework for interpretation of words and compounds in a discourse context which integrates a symbolic lexicon grammar. word-sense probabilities and a pragmatic component.

For example the first two senses of the noun diet given in WordNet are 1. a prescribed selection of foods fare - the food and drink that are regularly consumed 2. legislature legislative assembly general assembly law-makers Most English speakers will share the intuition that the first sense is much more common than the second and that this is partly a property of the word and not its denotation since near-synonyms occur with much greater frequency. Frequency differences are also found between senses of derived forms including morphological derivation zero-derivation and compounding . For example canoe is less frequent as a verb than as a noun and the induced action use e.g. they canoed the kids across the lake is much less frequent than the intransitive form with Alex Lascarides Centre for Cognitive Science and Human Communication Research Centre University of Edinburgh 2 Buccleuch Place Edinburgh EH8 9LW Scotland UK alexScogsci.ed.ac.uk location PP they canoed across the lake .1 A derived form may become established with one meaning but this does not preclude other uses in sufficiently marked contexts e.g. Bauer s 1983 example of garbage man with an .
