Before revision:  CAPSAR adopts a hierarchical structure of capsules and learns interactive patterns between aspects and sentiments through packaged sentiment-aspect reconstruction  . Capsules in CAPSAR are capable of communicating with other capsulesthrough a sharing-weight routing algorithm.
After revision:  CAPSAR adopts a hierarchical structure of capsules and learns interactive patterns between aspects and sentiments through packaged sentiment-aspect reconstruction procedure during the training. As a result, coherent patterns between aspects and sentimental expressions are encapsulated by these sentiment capsules . Capsules in CAPSAR are capable of communicating with other capsulesthrough a sharing-weight routing algorithm.
