Abstract

In this paper, we propose a multi-roles graph model for extractive single-document summarization. In our model, we consider that each text can be expressed in some important words which we call roles. We design three roles, including noun role, verb role and numeral role, and build a multi-roles graph according to these three roles to represent a text. And then we project this graph into three single role graphs according to the role of nodes. After that, we extract some import features from these four graphs by applying a modified PageRank algorithm and then combine them with some statistical features such as sentence position and the length of sentence to represent each sentence. Finally we train a random forest model to learn the pattern of selecting important sentences to generate summaries. To evaluate our model, we perform some experiments on DUC2001 and DUC2002 and achieve 13.9% improvement over latest methods. Besides, we also obtain best results in ROUGE-2 compared with some classic methods.
