Left-Center-Right Separated Neural Network for Aspect-based Sentiment Analysis with Rotatory Attention

3 Feb 2018Shiliang ZhengRui Xia

Deep learning techniques have achieved success in aspect-based sentiment analysis in recent years. However, there are two important issues that still remain to be further studied, i.e., 1) how to efficiently represent the target especially when the target contains multiple words; 2) how to utilize the interaction between target and left/right contexts to capture the most important words in them...
