PURPOSE: To flexibly convert an expression of a 1st natural language into an expression of a 2nd natural language.
CONSTITUTION: A conversion dictionary 7 which is used by a conversion part consists of four conversion dictionaries, i.e., a large-range conversion dictionary 71 wherein plural unit sentences (expression unit composed of a case element, an adverb element, and a predicate) are described as a group, an idiomatic conversion dictionary wherein case elements consisting principally of predicates of unit sentences and specific nouns are handled as a group, a pattern conversion dictionary 73 wherein relations between meaning attributes of the predicates of the unit sentences and the nouns of the case elements are handed as a group, and a general conversion dictionary 74 which give equivalents by the word. The conversion part performs conversion from the 1st natural language to the 2nd natural language by performing large-range conversion, idiomatic conversion, pattern conversion, and general conversion in order for an analysis result by using the large-range conversion dictionary 71, idiomatic conversion dictionary 72, pattern conversion dictionary 73, and general conversion dictionary 74.
