Character string dictionary construction method, character string dictionary search method, and character string dictionary processing system

摘要

A multicore CPU of a text string data analyzing device: loads a plurality of blocks obtained by dividing a text string dictionary into a memory; executes, in parallel on block groups executable independently of each other, an entry registration process of registering, character by character, unregistered text strings of text string data as new entries in the blocks in order from last characters; and outputs, as BW transformed data of the text string dictionary in which the text string data is already registered, a text string obtained by coupling text strings registered in entries of the blocks in a state in which no unregistered text strings of the blocks exists.
