Disclosed herein is a machine translation system which can automatically
switch from one or more dictionaries to more appropriate dictionaries for translating
a first language to a second language. As a dictionary constitution, a base dictionary
and domain dictionaries can be provided. The domain dictionary can be divided into
a compound word dictionary that includes triggers for switching dictionaries and
a compound word dictionary that does not include triggers for switching the dictionaries.
When a compound word included in the compound word dictionary that includes triggers
for switching the dictionaries is detected during source text analysis, a priority
of the concerned domain dictionary can be set higher than that of the base dictionary.
Moreover, the domain dictionary can be subdivided into a main domain dictionary
and a sub-domain dictionary.
