Abstract

The invention discloses a comment word emotion analysis method and system based on deep learning. The method includes the steps: receiving a text to be commented, and segmenting the text to be commented to obtain a word sequence; transforming the word sequence into a corresponding word vector sequence by a word vector generation model; judging whether the word sequence comprises emotion tendency words or not according to a domain emotion dictionary, acquiring a corresponding expansion word vector according to the emotion tendency words and adding the expansion word vector into the word vector sequence; inputting the word vector sequence with the added expansion word vector into an emotion judgment model and outputting judgment results. A traditional word vector is expanded based on the domain emotion dictionary, the information intensity of domain emotion words is enhanced, emotion tendency of the domain emotion words in a specific domain can be accurately recognized, and emotion tendency analysis accuracy is effectively improved.
