METHOD AND DEVICE FOR GIVING TAG TO INFORMATION STRING AND RECORDING MEDIUM RECORDED WITH THE METHOD

摘要

PROBLEM TO BE SOLVED: To easily deal with the specification change or addition of a tag by automatically giving the tag to an information string and easily identifying the replacement of giving a certain specified tag. SOLUTION: An input means 11 fetches the information string through an input/output device 2. A morpheme analytic means 12 adds morpheme information to each word included in the inputted information string. A semantic analytic means 13 gives a semantic category to the inputted word and morpheme information string. A replacing means 14 gives a tag by performing replacement to the information string consisting of words and morphemes or information string consisting of words, morphemes and semantic category. On the basis of a series of simple replacement rules for giving one tag to the inputted information string, the information string can be tagged and the respective simple and independent replacement rules are added, deleted and changed to deal with the specification change or addition of the tag.
