摘要：In this study, we propose the metrics to measure textual coherence by considering the document structure such as section, paragraph, and sentence. We suppose that when textual coherence is captured by considering the document structure, it is possible to fit human intuition. In this metrics, we first make graph structures at each document structure base on sentence similarity. Next, we recursively aggregate the coherence values of structures at a layer in a bottomup manner. We produce test data employing the sentence ordering task for individual layers. We assess the proposed metrics employing sentence ordering tasks: discrimination and insertion. We compare the performance of our metrics with the conventional graph-based local coherence model. The our metrics outperforms, in particular, at sentence ordering tasks conducted of the section layer; it follows that the proposed metrics works well for a structured document as containing sections, paragraphs such as a technical paper and a product manual.
