2000年初,Hu等[1]首次建立了基于规则的细粒度情感分析模型,命名为基于特征的观点摘要(Feature-based Opinion Summarization),受到学术界关注,带动了该领域技术方法的发展。2010年,Thet等[2]明确提出了方面级情感分析(Aspect Based Sentiment Analysis,ABSA)的概念,并定义评论对象“方面”为实体的属性或实体的组成部分。
Aspect-based sentiment analysis (ABSA) is one of the most challenging problems in opinion mining especially for the language with a complex structure like Vietnamese. Many studies tackle this problem by separating it into two subtasks: opinion target extraction and sentiment polarity detection. ...
