System and method for recognizing sentiment of user's feedback

Abstract

According to various embodiments, a system for recognizing a sentiment of a user's feedback is provided. The system comprises: an encoder configured to receive an input text for the user's feedback, break up the input text into text tokens, and encode each text token; and a decoder connected to the encoder and configured to output a sentiment score for the input text, wherein the encoder is further configured to read the encoded text token in a bidirectional manner to obtain a forward node value and a backward node value, and concatenate the forward node value and the backward node value together to obtain a vector representing semantic meaning of the input text, and the decoder is configured to receive the vector from the encoder, obtain a probability of each sentiment score by mapping the vector into each sentiment score, and determine the sentiment score for the input text based on the probability.

Dependencies are inferred from the claim text.
