中文摘要: 及时有效分析互联网越南新闻事件对把握越南事件舆情观点有重要的作用,本课题针对新闻事件及汉越语言特点,研究汉越双语事件本体知识库及语义语料库构建、新闻事件话题发现与追踪、事件舆情观点挖掘方法。首先,定义新闻事件分类体系,构建事件类别术语、事件关系、事件观点等义原类层次树,构建汉越双语事件本体知识库及带语义要素标记的事件语料库,为分析汉越事件提供知识与语料基础。其次,针对汉越双语事件话题产生演化特点,融合双语语言知识、事件本体知识、事件对齐等特征,研究融合双语主题分析和进化聚类的话题发现与追踪方法,解决双语混合事件话题探索与追踪问题;在此基础上,针对事件间及事件内部特征关联特性,融合事件间关联、句子间关联、实体关联及双语关联等特征,研究基于图模型的双语观点句识别、观点分析、持有人分析及倾向性分析方法,解决融合关联特征的双语事件观点挖掘问题。成果将为有效分析汉越双语舆情事件提供资源及技术支撑。
