    • PURPOSE:To shorten a retrieving time of a dictionary, and to process an addition of a new word in a short time, by storing correlative compression and ''Kana'' (Japanese syllabary) as 1 byte, storing a large Japanese dictionary by small capacity, and executing its correlative compresson by a transfer unit of a secondary storage device. CONSTITUTION:When a dictionary data is stored in a dictionary storage device 13, a frequency information encoding device 12 for encoding a unit of information of a part of speech is connected to a correlative compression device 11 for inputting a dictionary data, and size of a ''Kana'' (Japanese syllabary) character code is made smaller than size of a chinese character code. Also, from a word fetch device 14, reading of a word data and length of a character-string of a key are stored as variable length. furthermore, by a new word adding and registering device 10 for inputting a new word data, a new word adding flag of 1 bit is provided on 1 word of its data and is stored. In this way, a retrieving time of a dictionary is shortened, and also a work for adding a new word later on is executed in a short time.
