Abstract | It performs unsupervised classification on news articles based on disputant relations, and helps readers intuitively view the articles through the opponent-based frame. |

Introduction | Summarization has been applied to different genres, such as news articles , scientific articles, and speech domains including broadcast news, meetings, conversations and lectures. |
Opinion Summarization Methods | To obtain this, we trained a maximum entropy classifier with a bag-of-words model using a combination of data sets from several domains, including movie data (Pang and Lee, 2004), news articles from MPQA corpus (Wilson and Wiebe, 2003), and meeting transcripts from AMI corpus (Wilson, 2008a). |
Related Work | Previous studies have used various domains, including news articles , scientific articles, web documents, reviews. |
