NETMET: A program for generating and interpreting metaphors

Metaphors have computable semantics. A program called NETMET both generates metaphors and produces partial literal interpretations of metaphors. NETMET is based on Kittay's semantic field theory of metaphor and Black's interaction theory of metaphor. Input to NETMET consists of a list of literal propositions. NETMET creates metaphors by finding topic and source semantic fields, producing an analogical map from source to topic, then generating utterances in which terms in the source are identified with or predicated of terms in the topic. Given a metaphor, NETMET utilizes if-then rules to generate the implication complex of that metaphor. The literal leaves of the implication complex comprise a partial literal interpretation.Eric Steinhart has an MA in philosophy (Boston College) and completed his PhD dissertation (Formal Semantics for Metaphors) at SUNY at Stony Brook. He has written on technology, analogy, metaphor and idealism. His publications include Beyond the Proportional Analogy: A Structural Model of AnalogyPragmatics and Cognition, 2, 1 (1994). He is interested in the application of computational methods to philosophical topics and is working on a computational model of idealistic metaphysics.
