APPARATUS, METHOD, AND PROGRAM PRODUCT FOR TRANSLATION AND METHOD OF PROVIDING TRANSLATION SUPPORT SERVICE

An apparatus selects from among a plurality of translation records a translation record for use in translation of a newly received text. Each of the translation records stores with respect to past translation results at least one pair of a source-language text, being a divided part corresponding to a translation segment in the received text, and a target-language text corresponding to the source-language text. A first key generation unit generates an input key for each of the translation segments in the received text. A translation segment is encoded based on a predetermined conversion rule. An acquisition unit acquires a translation record key in which a source-language text is encoded based on the predetermined conversion rule. A key search unit determines whether a translation record key identical with each of the input keys is present or not. A first count unit counts a quantity of input keys that have translation record keys identical with each of the translation records. A determination unit determines a translation record for use in translating the received text on the basis of the count result for each segment.
