While sentiment analysis has been widely used in public opinion to explore tendency of users for a target product from large online review data; less work focus on aspect-level or fine-grained sentiment analysis in which the polarity of not only the aspect of a target object but also the attribute of that given aspect should be determinated. Recent work regards aspect-level sentiment analysis as two separate tasks; i.e; aspect classification and sentiment analysis; and this pipeline method leads to error propagation. To address this issue; this paper proposes an improved multi-way matching deep neural network model for fine-grained sentiment analysis; which jointly models the two tasks in one phase and improves current attention by directly capturing past attention in the multi-round alignment architecture; so as to prevent error propagation and attention deficiency problems. Experimental results on fine-grained sentiment analysis data sets of catering industry indicate that the F1 score of this model in actual test set reaches 0.7302 and EM score 87.1973; which are higher than baseline DocRNN model by 3.8% and 0.88% in F1 and EM; and are higher than SVM by 15.4% and 25.6%; which verified that our model could effectively predict fine-grained sentiment and have better generalization performance. © 2020; Springer-Verlag London Ltd; part of Springer Nature;
