Generating Illustrated Diagram to Support Understanding of News Summaries Based on Anaphora Resolution and Verb Thesaurus

Abstract

The present study is aiming to automatically generate news summaries using illustrated diagram that enables users to understand an overview of the news. To generate illustrated diagram, zero anaphora resolution is needed because the elements of the statements are often omitted in Japanese sentences. In this study, we propose a method for zero anaphora resolution focusing on human nouns that appear in diagram based on the centering theory, and a method for hierarchical management of illustrated diagram using the verb thesaurus. We conducted an experiment to compare summaries generated by the system and summaries of existing conventional services. The experimental result indicated that the illustrated diagram is useful to understand the overview.
