    <Paragraph position="0"> In intra-sentential zero-anaphora resolution, syntactic patterns of the appearance of zero-pronouns and their antecedents are useful clues. Taking Japanese as a target language, we have empirically demonstrated that incorporating rich syntactic pattern features in a state-of-the-art learning-based anaphora resolution model dramatically improves the accuracy of intra-sentential zero-anaphora, which consequently improves the overall performance of zero-anaphora resolution.</Paragraph>
    <Paragraph position="1"> In our next step, we are going to address the issue of how to find zero-pronouns, which requires us to design a broader framework that allows zero-anaphora resolution to interact with predicate-argument structure analysis. Another important issue is how to find a globally optimal solution to the set of zero-anaphora resolution problems in a given discourse, which leads us to explore methods as discussed by McCallum and Wellner (2003).</Paragraph>
