Complex Types: Modeling Polysemy in Natural Language

A Graduate Research Seminar

Fall 2002

James Pustejovsky

Location: Volen Center, Room 101
@ Brandeis University
Time: Th 3:30 pm.


The goal of this seminar is to explore the nature of polysemy in natural language, and specifically, as modeled in terms of "complex types" in Generative Lexicon Theory. Complex types (also known as dot objects) are concepts that cross conventional categories in semantic typologies for language. The best known grammatical indicator of dot objects is the presence of "polysemy governed by a logical relation." For example, in (1) below, the polysemy exhibited by the noun "book", according to Generative Lexicon, is a reflection of its logical type; that is, a book can refer both to propositional content (information) or a physical object.

(1) a. John did not believe that book.
    b. John burned that book.
As a complex type, it is a specific reified relation between informational content and its physical manifestation. This effect is not an isolated phenomenon, but in fact manifests itself in all major areas of the lexicon, and hence generally throughtout the grammar. Other studied cases of complex types include event.proposition polysemy (such as "exam"), event.event polysemy (such as "examination", "construction"), event.human polysemy (such as "appointment"), and object.aperture polysemy (such as "door" and "window"). Other complex types potentially include certain attribute.scale polysemies, such as "temperature" and "height".

In this seminar, we examine linguistic phenomena in a number of diverse languages that exhibit or appear to exhibit the behavior of complex types, focusing also on verbal and adjectival complex types. It is hoped that by broadly investigating this phenomenon cross-linguistically, a richer, more descriptive theory of complex types will emerge.
