PURPOSE:To prevent retrieval omission due to erroneous KANJI (Chinese character)/KANA (Japanese syllabary) conversion from occurring by providing an equivalent rule information table and a similarity rule information table prepared from the statistical information of both the KANJI of a proper noun of Japanese language and its reading. CONSTITUTION:Japanese language information W provided with a KANA string accumulated in a Japanese language information accumulation means 5 in advance is retrieved based on the KANA string of Japanese language information W' from a Japanese language information input means 1. At this time, the equivalent rule information table D or the similarity rule information table R is referred to, and new KANA strings Di and Ri are generated from retrieved equivalent rule information and similarity rule information, and they are accumulated in the Japanese language information accumulation means 5. Also, a set of plural partial KANA strings which defines equivalent relation or similarity relation, and a representative KANA string which represents a position (leading, ending, or intermediate position) in the KANA string where the partial KANA string appears and the set of KANA strings are described on the equivalent rule information table D or the similarity rule information table R, respectively.
