"Issues in Knowledge-Based Machine Translation"
Knowledge-based MT stresses the use artificial intelligence techniques.
KBMT systems are traditionally designed around a cascaded analyzer
containing a syntactic parser and a semantic/pragmatic interpreter for the
input language. Until recently relatively less attention has been paid to
other modules of a KBMT-system, notably the generation component. In my
talk I will describe the KBMT-89 system developed at CMU CMT. After
describing the architecture of the system, I will concentrate on a) the
requirements of knowledge acquisition for KBMT; b) the ways of invoking
human assistance in cases of analyzer failure; and c) the peculiarities of
the generation module in a KBMT system.
