At first, heading is written by the writing method for Japanese including 'ROMAJI'. Then only a part of the end form of a verb or the like or the united form of a conjugation part with another specific word is registered as the heading of the dictionary and the dictionary is used as a coded dictionary to be mechanically retrieved. In addition, the connection table for extended words including only a part of the end form and the united form between the conjugation part of a verb or the like and another specific word is used. Consequently, a memory can be efficiently utilized and rapid processing can be attained.
