【摘要】:新聞文本情感摘要是指通過提煉、濃縮而產(chǎn)生表達(dá)文本全局情感意見的摘要,旨在幫助人們快速獲取文本的情感傾向,F(xiàn)有的文本摘要方法僅考慮主題及句子特征等因素,無法獲取帶有情感意見的文本摘要。針對這一問題,提出了融合句子情感和主題相似性的中文新聞文本情感摘要。首先,對文本中的句子進(jìn)行情感標(biāo)注;然后,在LexRank算法中加入情感信息計算句子相似度;最后,根據(jù)新聞標(biāo)題的特殊性計算句子與標(biāo)題的相似性,再綜合以上步驟的結(jié)果得到最終的情感摘要。實(shí)驗結(jié)果表明,在ROUGE-1、ROUGE-2和ROUGE-W三個指標(biāo)上,該方法比傳統(tǒng)的LexRank算法均有提升,證明了同時考慮情感信息和主題信息能夠更加有效地生成體現(xiàn)文本主要觀點(diǎn)、情感的情感摘要。
[Abstract]:The emotional summary of news text is a summary which can express the whole emotional opinion of the text by abstracting and concentrating. It aims to help people get the emotional tendency of the text quickly. The existing text summary methods only consider the topic and sentence features, and can not get the text summary with emotional opinions. In order to solve this problem, an emotional summary of Chinese news text is proposed, which combines sentence emotion and subject similarity. Firstly, the sentences in the text are labeled with emotion, and then the sentence similarity is calculated by adding emotional information into the LexRank algorithm. Finally, the similarity between the sentence and the title is calculated according to the particularity of the news title, and the final emotional summary is obtained by synthesizing the results of the above steps. The experimental results show that the proposed method is better than the traditional LexRank algorithm in terms of ROUGE-1,ROUGE-2 and ROUGE-W. It is proved that both emotional information and subject information can be taken into account more effectively to generate the main points of view of the embodied text. An emotional summary of emotions.
