DICTIONARY DATA COMPRESSION APPARATUS, ELECTRONIC DICTIONARY DEVICE, COMPRESSED DICTIONARY DATA PRODUCTION METHOD AND PROGRAM

摘要

PPROBLEM TO BE SOLVED: To increase the compression efficiency of a dictionary coding method by discretely selecting entry unit data to create a reference part and changing the coding method in dependence on a character string. PSOLUTION: A CPU 10 discretely selects entry unit data from original English-Japanese dictionary data 200 as a processed English-Japanese reference part 302, and handles the remaining entry unit data as main data part intermediate data 306. The CPU 10, for character strings of a predetermined word length or longer, executes a global search program 214 to decide character strings to be coded, and for the other character strings, executes a local search program 216 to decide character strings to be coded. A coding program 218 is then executed to code the main data part intermediate data 306 into a coded English-Japanese main data part 304. PCOPYRIGHT: (C)2005,JPO&NCIPI
