An image-schematic system of thematic roles

We describe a system of thematic roles and frames designed to address a number of problems in semantic representations at the lexical semantic level. Our primary objective is broad expressiveness, so that real domains can practically be encoded. However, for both empirical and computational reasons we limit the number of role types to four, allocating this structure to the strongest associations. We show how the system incorporates image-schematic semantics to encode various schematization operations relating to scales and reification
