摘要

PROBLEM TO BE SOLVED: To highly precisely achieve tagging in an unknown document by learning the relationship between the features of a target word and peripheral words including words before and after the target word and a correct tag.

SOLUTION: A learning processing step generates a plurality of learning results by using the group of a pair of: the features of a target word and peripheral words at the both sides included in tagged correct document data; and a correct tag. A decision processing step repeats the decision of the predicted tag of each target word from the features of the target word and the peripheral words at the both sides included in unknown document data to be tagged to decide the correct tag by using the plurality of learning results learned by using the features of the target word and the peripheral words.
