| 摘 要： | 该文提出一种融入多特征的汉越双语新闻观点句抽取方法。首先针对汉语和越南语标记资源不平衡的问题,构建了汉越双语词嵌入模型,用丰富的中文标记资源来弥补越南语标记资源的缺失。并且该文认为句子的主题特征、位置特征和情感特征对观点句分类具有重要作用,因此将这些特征分别融入词向量和注意力机制中,实现句子语义信息和情感、主题、位置特征的结合。实验表明,该方法可有效提升越南语新闻观点句抽取的准确率。

| Abstract: | This paper proposes a Chinese-Vietnamese bilingual news perspective sentence extraction method that incorporates multiple features. Firstly, for the problem of unbalanced resources in Chinese and Vietnamese, this method constructs a Chinese-Vietnamese bilingual word embedding model. We use rich Chinese tag resources to make up for the lack of Vietnamese tagging resources. Then, the emotional, topical and positional features of sentences are integrated into the word vector and attention mechanism respectively. Experiments show that this method can effectively improve the accuracy of Vietnamese news perspective sentence extraction. |
