Abstract

Metaphor's peculiar property to yield cognitive insight-- often in otherwise false sentences -- has been the focus of contemporary studies of metaphor. In Metaphor: Its Linguistic Structure and Cognitive Force, Eva Kittay develops the semantic field theory of metaphor (SFTM). The task of the present work is to formalize some of the central claims of SFTM. Formalization forces us to make the central concepts of SFTM precise and operational, and it enables us to evaluate the consistency and explanatory power of SFTM through empirical testing. To empirically test our formalization of SFTM, we constructed a working computer program from it. This program, called NETMET, is highly successful in generating syntactically complex and semantically interesting metaphors. Its success provides empirical confirmation of SFTM.
