8 Conclusion
</SectionTitle>
    <Paragraph position="0"> This paper proposed a method by which 5WlH (who, when, where, what, why, how, and predicate) information is used to classify and navigate Japanese-language texts. 5WlH information, extracted from text data, provides an access platform with three functions: episodic retrieval, multi-dimensional classification, and overall classification. In a six-month trial, the platform was used by 50 people to access 6400 newspaper articles.</Paragraph>
    <Paragraph position="1"> The three functions proved to be effective for office documentation work and the extraction precision was approximately 82%.</Paragraph>
    <Paragraph position="2"> We intend to make a more quantitative evaluation by surveying more users about the functions. We also plan to improve the 5W1H extraction algorithm, dictionaries and the user interface.</Paragraph>
