ABSTRACT:
An apparatus for compressing text data generated in advance uses character data defined in a code table. The apparatus includes a word extractor which extracts words to be coded from the words in the text data; a code allotter which allots a code to each extracted word that is defined in the code table and different from the codes allotted for the character data; a dictionary generator which generates a dictionary for defining a correspondence between the extracted words and the respective codes allotted to the extracted words; a code replacer which replaces the extracted words with their respective allotted codes to compress the text data; and a storage device which stores the generated dictionary and the compressed text data. The data amount for each text is reduced to improve the storage efficiency of a memory.
