TERM SYNONYM ACQUISITION METHOD AND TERM SYNONYM ACQUISITION APPARATUS
First Claim
1. A term synonym acquisition apparatus comprising:
- a first generating unit which generates a context vector of an input term in an original language and a context vector of each synonym candidate in the original language;
a second generating unit which generates a context vector of an auxiliary term in an auxiliary language that is different from the original language, where the auxiliary term specifies a sense of the input term;
a combining unit which generates a combined context vector based on the context vector of the input term and the context vector of the auxiliary term; and
a ranking unit which compares the combined context vector with the context vector of each synonym candidate to generate ranked synonym candidates in the original language.

Abstract
A term synonym acquisition apparatus includes: a first generating unit which generates a context vector of an input term in an original language and a context vector of each synonym candidate in the original language; a second generating unit which generates a context vector of an auxiliary term in an auxiliary language that is different from the original language, where the auxiliary term specifies a sense of the input term; a combining unit which generates a combined context vector based on the context vector of the input term and the context vector of the auxiliary term; and a ranking unit which compares the combined context vector with the context vector of each synonym candidate to generate ranked synonym candidates in the original language.

9. A term synonym acquisition method comprising:
-
generating a context vector of an input term in an original language and a context vector of each synonym candidate in the original language; generating a context vector of an auxiliary term in an auxiliary language that is different from the original language, where the auxiliary term specifies a sense of the input term; generating a combined context vector based on the context vector of the input term and the context vector of the auxiliary term; and comparing the combined context vector with the context vector of each synonym candidate to generate ranked synonym candidates in the original language.

10. A computer-readable recording medium storing a program that causes a computer to execute:
-
a first generating function of generating a context vector of an input term in an original language and a context vector of each synonym candidate in the original language; a second generating function of generating a context vector of an auxiliary term in an auxiliary language that is different from the original language, where the auxiliary term specifies a sense of the input term; a combining function of generating a combined context vector based on the context vector of the input term and the context vector of the auxiliary term; and a ranking function of comparing the combined context vector with the context vector of each synonym candidate to generate ranked synonym candidates in the original language.
