The analysis of these aspect ratings could not only benefit mining interested aspects for users, but also help companies better understand the major pros and cons of the product.
for aspect a k , we can use a softmax layer to project c k into sentiment distribution p(d, k) over L classes: where p l (d, k) is used to represent the predicted probability of sentiment class l for d based on a k and W lk , b k are parameters of softmax layer for classifying review c k .
