%0 Journal Article %J International Journal of Expert Systems %D 1996 %T A Multi-Level Approach to Interlingual MT: Defining the Interface between Representational Languages %A Dorr, Bonnie J %A Voss,C.R. %X This paper describes a multi-level design, i.e., a non-uniform approach to interlingual ma-chine translation (MT), in which distinct representational languages are used for di erent types of knowledge. We demonstrate that a linguistically-motivated \division of labor" across multiple representation levels has not complicated, but rather has readily facilitated, the identi cation and construction of systematic relations at the interface between each level. Our approach assumes an interlingua derived from the lexical semantics and predi- cate decomposition approaches of Jackendo (1983; 1990) and Levin and Rappaport-Hovav (1995a; 1995b). We describe a model of interpretation and representation of natural lan- guage sentences which has been implemented as part of an interlingual MT system called PRINCITRAN. %B International Journal of Expert Systems %V 9 %P 15 - 51 %8 1996/// %G eng %N 1
