Abstract
PURPOSE:To realize an easy and highly efficient retrieval for the thesaurus relation among plural key words, by decreasing the retrieving range of the input key word with use of an index key word table on which the head words of the key words are distributed adjacently. CONSTITUTION:The writing and reading is controlled for memories 23, 24 and 25 through a retrieval control part 21 of a thesaurus retrieving part 2 to which varous codes givent from a keyboard device 1 are supplied. On the other hand, the input key word given from the device 1 is stored and held in the memory 23 to be sent to a thesaurus part 4 and at the same time compared 22 with the thesaurus information stored in the memory 24 to be supplied to the part 21. Then the character code train of the head word of the key word supplied from the memory 23 is stored in a memory 47. At a thesaurus control part 41, the thesaurus information given from an index table 43, a word table 44, key word table 45 and a relation key word table 46 are retrieved and read by referring to the above-mentioned character code train.
