Abstract

The invention discloses an emotion analysis method and device, and relates to the technical field of processing of natural languages. By means of the emotion analysis method and device disclosed by the invention, the emotion analysis accuracy rate is increased. The technical scheme in the invention comprises the following steps of: extracting an emotional word sequence from a target text, wherein the emotional word sequence includes sequentially extracted emotional words and non-sememic words; generating an emotional word sequence vector corresponding to the emotional word sequence; according to a pre-set classification model, obtaining an emotional mark corresponding to the emotional word sequence vector of the target text, wherein the corresponding relationship between the emotional word sequence vector and the emotional mark is stored in the pre-set classification model; and taking the obtained emotional mark as an emotion analysis result of the target text. The emotion analysis method and device disclosed by the invention are mainly used for analyzing emotion of the target text.

Description

technical field [0001] The invention relates to the technical field of natural language processing, in particular to a sentiment analysis method and device. Background technique [0002] In recent years, sentiment analysis technology has become a hot topic in the field of natural language processing research. The goal of sentiment analysis is to mine the opinions expressed by users and the emotional polarity from the text. Mining the emotional tendency in the text can be used to help other users make decisions. Therefore, sentiment analysis technology has attracted the attention of many researchers in the field of natural language processing and has great application value. [0003] At present, the emotional tendency of the target text is obtained through the tagging sequence rules, that is, the tagging sequence rules are formed based on the emotional category tags of each sentence in the training text and the emotional tags of the training text, and finally the sentiment of...
