7 Conclusion
</SectionTitle>
    <Paragraph position="0"> This paper proposed a fully automatic method of building polarity-tagged corpus from HTML documents. In the experiment, we could build a corpus consisting of 126,610 sentences.</Paragraph>
    <Paragraph position="1"> As a future work, we intend to extract more opinion sentences by applying this method to larger HTML document sets and enhancing extraction rules. Another important direction is to investigate more precise model that can classify or extract opinions, and learn its parameters from our corpus.</Paragraph>
