Abstract:
PURPOSE:To execute the processing at a high speed by using a category table which has been constituted by classifying in advance a category into groups at every element of a feature vector, and a group selection table, and executing a cumulative calculation of a decided value only with regard to some category names which are selected at every vector element. CONSTITUTION:A group selection table 2 is retrieved by an element value of an input feature vector, a group name of a group having a positive decided value except '0' and its decided value are read out, and subsequently, a category name is read out by retrieving a category table 1 by the group name which has been read out. A decided value cumulation processing means 4 cumulates the decided value onto an evaluated value table 4a in accordance with the category name which is read out by a selection processing means 3, and calculates an evaluated value. In case of a sort processing, in a sort processing means 5, the category name corresponding to the evaluated value given from the decided value cumulation processing means 4 is rearranged in a candidate category table in order from a larger one, and a candidate category extending from the first candidate category whose evaluated value and cumulated value are maximum to a prescribed rank order is outputted.
