Probably the most famous example of a system with what we have called a transformer architecture is SYSTRAN. This is described in [Hutchins and Somers1992]. A recent discussion can be found in [Wilks1992].
A more detailed overview of transfer systems can be found in [Arnold1993].
Examples of transfer systems include the following, ARIANE [Vauquois and Boitet1985], SUSY [Maas1987], MU (the Japanese National Project) [Nagao et al. July 1986], METAL [Slocum et al. 1987], [Bennett and Slocum1988], TAUM-AVIATION [Isabelle1987], ETAP-2 [Apresian et al. 1992], LMT [McCord1989], EUROTRA [Arnold1986,Arnold and des Tombe1987,Copeland et al. 1991a,Copeland et al. 1991b], , CAT-2 [Sharp1988], MIMO [Arnold and Sadler1990], MIMO-2 [van Noord et al. 1990], ELU [Estival et al. 1990]. Several of these systems are discussed in detail in [Hutchins and Somers1992].
Among interlingual systems , the following are noteworthy: Rosetta [Landsbergen1987b,Landsbergen1987a], KBMT [Goodman1989], [Goodman and Nirenburg1991]. A recent overview is given in [Nirenburg1993]. [Hutchins and Somers1992, Chapter 6,] is also recommended. One interlingual approach that we have not mentioned here is that which uses a human language as the interlingual. The best known example of this is DLT, which uses Esperanto, see [Schubert1992] and [Hutchins and Somers1992, Chapter 17,].
