    <Paragraph position="0"> In this paper, we presented a simple method to handle complex sentences with the centering theory and described our framework that can identify the antecedents of zero pronouns in naturally occurring Japanese discourses. We also presented tile evaluation of our framework with real discourses, although the evaluation is not so large-scale to assert the effectiveness of our framework. Our simple method yielded the accuracy of 78% for the zero pronoun resolution.</Paragraph>
    <Paragraph position="1"> Since our method that is presented in this paper is based on the centering theory and basically uses only syntactic information, we plan to incorporate the semantic constraints that filter anomalous antecedents for zero pronouns, and take into account the global structure of discourses. We think the preliminary results of our system in this paper are promising since incorporating the information of semantic constraints and the global structure of discourses will improve the performance.</Paragraph>
