This paper proposes a method by which 5W1H (who, when, where, what, why, how, and predicate) infor- mation is used to classify and navigate Japanese- language texts. 5WlH information, extracted from text data, has an access platform with three func- tions: episodic retrieval, multi-dimensional classi- fication, and overall classification. In a six-month trial, the platform was used by 50 people to access 6400 newspaper articles. The three functions proved to be effective for office documentation work and the precision of extraction was approximately 82%.
