4 Conclusions
</SectionTitle>
    <Paragraph position="0"> In this paper we described our approach to coherent sentence ordering for summarizing newspaper articles. We conducted an experiment of sentence ordering through multi-document summarization. The proposed method which utilizes precedence relation of sentence archived good results, raising poor chronological orderings to an acceptable level by 20%. We also proposed an evaluation metric that measures sentence continuity and a amendment-based evaluation task. The amendment-based evaluation outperformed the evaluation that compares an ordering with an answer made by a human. The sentence continuity metric applied to the amendment-based task showed more agree- null ments with the rating result.</Paragraph>
    <Paragraph position="1"> We plan to do further study on the sentence ordering problem in future work, exploring how to apply our algorithm to documents other than newspaper or integrate ordering problem with extraction problem to improve each other. We also recognize the necessity to establish an automatic evaluation method of sentence ordering.</Paragraph>
