ABDUCK 会話理解システムの概要
Abstract:This paper offers a final report of the research results achieved so far by the author in natural-
language understanding for automatic interpreting telephone applications. The ABDUCK system
is designed to accept ambiguous surface-semantic feature-structure candidates output from the
parser, understand and disambiguate the utterance, and give as
output directly to the transfer
module feature-structure representations of the utterance at the surface-semantic, deep-semantic
("real meaning"), and illocutionary-force ("speech act") levels of representation. This results in a
significantly more natural translation. For instance, the system can understand unagi-da
sentences and the different meanings of "hai" and "wakarimashita". A previous paper has
discussed the theory of the system. This report presents the results of the ABDUCK
understanding/disambiguation system.
