5 Conclusions and Future work
</SectionTitle>
    <Paragraph position="0"> We proposed an approach to retrieve information from documents which are not annotated with any tags. We annotated documents with document structures and semantic tags by taggers, and retrieved information by using ranked region algebra. We showed what kind of data can be retrieved from documents in the experiments.</Paragraph>
    <Paragraph position="1"> In the discussion, we showed several points about the ranked retrieval for structured texts. Our future work is to improve a model, corpus etc. to improve the ranked retrieval for structured texts.</Paragraph>
