Abstract We propose a method for expanding the entries in a thesaurus using a di erent thesaurus constructed with another concept. This method constructs a mapping table between the concept codes of these two di erent thesauri. Then, almost all of the entries of the latter thesaurus are assigned the concept codes of the former thesaurus with the mapping table between them. To con rm whether this method is e ective or not,we construct a mapping table between the ''Kadokawa- shin-ruigo'' thesaurus (hereafter, ''ShinRuigo'') and ''Nihongo-goitaikei'' (hereafter, ''Goitaikei''), and assigne about 350 thousand entries with the mapping table. About 10% of the entries cannot be assigned automatically. It is shown that this method can save cost in expanding a thesaurus.
