Abstract
PURPOSE:To generate a list of words, whose frequency in appearance is higher than a certain value, to efficiently compress a file of a computer system by extracting the frequency in appearance of each word in the file and encoding words whose frequency in appearance exceeds the certain value. CONSTITUTION:A word as the compression object is read to a word extracting/ frequency counting part 2 from an input file 1 of a file compressing device and the frequency in appearance of the read word is detected. A list 3 of words, whose frequency in appearance exceeds the certain value, extracted by the word extracting/frequency counting part 2 is generated, and words of this list 3 are supplied to a compressing part 4. The word as the compression object from the file 1 is encoded in the compressing part 4 by the list 3. Words processed in the compressing part 4 are stored in an output file 5 as compressed data 6 and a word list 7, and frequency appearing words are efficiently compressed.
