A method of segmenting a text into words in which a dictionary search is made while using a character string in the text as a search key, and it is checked whether a word retrieved from the dictionary can be grammatically connected to another word adjacent thereto or not. Segmentation processing is carried out using only words registered in a word dictionary, processing for identifying an unknown word is carried out when the segmentation processing comes to a deadlock, and then the segmentation processing is continued for that portion of the text which follows the identified unknown word.
