ABSTRACT:
The capacity of a character feature dictionary is reduced, and stored as a feature dictionary. The capacity is reduced by clustering feature vectors in units of columns or rows for character features, by making m column vectors represent the column or row features, and by assigning 1 to m identification numbers. The capacity of the dictionary can be further reduced by representing a column or row feature with an addition sum of other column or row features, or differential features after clustering is performed, or by performing dimension compression for character features. Word recognition is performed by synthesizing a word feature for a comparison based on a word list to be recognized, and by making a comparison between a feature extracted from an input word and the synthesized feature. Or, a comparison between input word and input word features whose numbers of dimensions are different may be made with nonlinear elastic matching.
