Two Types of Adaptive MT Environments

A nurnher of propos'ds have come up hi reten! years for hybrhlizitlhm of MT.

While such pr(~jccls can be quite useful, we believe thnt i l is lime tc~ make tile next step in lhe desiy, n cd machine Ii.{inshtt ion systems and to move lOw;id i~dii])live, mulliplc-crlgine syslems. We describe Ihc architecture of an adaptive multi-engine MT system which uses each of the engines under tile circumstances which are most favorable for ;Is success.
