SOLUTION: A word division part 5 divides a transferred sentence to be retrieved in each word unit by referring to a word dictionary 10. Word attribute information is added to each divided word unit. The word division part 5 transfers respective divided words to a modification analyzing part 6. The analyzing part 6 checks the modification relation of respective transferred words and transfers modification information indicating modification relation between words to a retrieving sentence sorting part 7. The sorting part 7 stores a sentence to be retrieved in a retrieving sentence storing part 9 in a corresponding form between a word having modification relation with the input word and the sentence to be retrieved. The sorting part 7 repeats operation from the extraction of a sentence to be retrieved next from a sentence storing part 8 up to the transfer of the extracted sentence to a retrieving part 4, and when all unprocessed sentences to be retrieved disappear from the sentence storing part 8, ends a series of retrieving processing. |
