5 Conclusion
</SectionTitle>
    <Paragraph position="0"> In this paper, we propose the tree annotation tool which performs two-phase parsing for the intra-structure of each segment and the inter-structure after segmenting a sentence. The proposed tree annotation tool has the following characteristics.</Paragraph>
    <Paragraph position="1"> First, it can reduce manual effort to build a treebank. Experimental results show that it can improve approximately 60.0% and 24.5% as compared with the manual tree annotation tool and the tree annotation tool using one phase parsing.</Paragraph>
    <Paragraph position="2"> Second, it can prevent the initial syntactic errors of a word or a phrase from propagating to the whole syntactic structure without any modification of the parser because it takes sentence segmentation. Third, it can shift the responsibility of extracting the reliable syntactic rules to the parser.</Paragraph>
    <Paragraph position="3"> For future works, we will try to develop an automatic segmentation method to minimize manual effort.</Paragraph>
