PURPOSE:To compress a coded sentence by extracting sequentially character code strings having the same number of characters from a stored character code strings and outputting a word code corresponding to the character code string when they are retrieved and coincident. CONSTITUTION:A character code string of a sentence mixed with Kanji (Chinese character) and Kana (Japanese syllabary) desired to be compressed is fed sequentially from an inlet 1 to an input register section 2. The length of the register is selected by 2, 3 or 4 characters by selecting the length of the unit of conversion word. The code string of 2 characters stored in the input register section 2 is fed to a word retrieval section 3 and when a word stored in an electronic dictionary storage section 9 is retrieved and when they are coincident, the content of a word code supplied to the word is read and outputted to an output register section 5 via a compression control section 4. The code stored in the compression code input register section 12 is fed to a code retrieval section 13, a word code stored in the electronic dictionary storage section 9 is retrieved and the 2-character word of the index corresponding to the code is read and fed to an original sentence output register section 15 via an expansion control section 14 from the path 16. |
