In this paper, we describe a tool designed to gener- ate semi-automatically the sortal constraints spe- cific to a domain to be used in a natural language (NL) understanding system. This tool is evaluated using the Sll,I Gemini NL understanding system in tile ATIS domain. of work we put into the first domain application 1. In this paper, we describe tile results of us- ing this semi-automatic tool to port the (',e, udlii NL system to the ATIS domahi, a (lomltin that (ienlini had ah'eady been ported to, arid for which it ]lad achiew~,d high perl'orluance ~ttld gi'al'l-illiati- cal coverage using hand-written sortal constraints. Chossing a known domain, rather than a new one, allowed us to compare tile performance of tile de- rived sorts to the hand-written ones, holding the domain, grammar,...
