Information processing system

Abstract

An information processing system for normalizing an input character string and storing the normalized character string is provided whereby the required storage capacity can be cut down. Normalizing means normalizes an input character string, for example,, and generates, which is then supplied to restoration information generating means and storing means. The restoration information generating means is supplied also with the original character string, besides the normalized character string, and generates restoration information “F@&” consisting of ASCII characters, which is supplied to storing means. The storing means stores the normalized character stringand the restoration information “F@&” in a manner associated with each other. When the normalized character stringstored in the storing means is specified, restoring means acquires the corresponding restoration information “F@&” and, based on the acquired information, restores the original information. Consequently, the required storage capacity of the storing means can be cut down, compared with the case of storing also the input character string.
