Abstract: A method and system for morphologizing written or printed texts, including Japanese texts are obtained in accordance to codes. The longest morphemes are divided one at a time from the characters in a sentence. This is achieved by forming the longest morpheme from the remaining characters in the sentence which is listed in a dictionary of valid morphemes and determining if it is conjunctive with the previously divided morpheme. To determine if a formed morpheme is conjunctive, associated pairs of front and back connection codes are retrieved. If a front connection code of one retrieved pair and a back connection code of a pair of connection codes of the previously divided morpheme are co-listed in a table of permissible relationships, the formed morpheme is conjunctive. If no character may be divided from the remaining characters in the sentence, a previously divided morpheme is redivided.
