Abstract

The invention relates to an emotion classification method and system. The emotion classification method comprises the following steps: according to a data flow interface provided by a social network platform, obtaining data with emoticons, and marking the data according to the emoticons; according to a CBOW-emotion dictionary training model, constructing an emotion word vector dictionary by taking the marked data as input; according to provided training data, querying the emotion word vector dictionary, converting the training data into first mathematic vectors, sending the first mathematic vectors into a classifier, and training a classification model; and according to the classification model, performing emotion classification on social network data. According to the invention, texts are represented by emotion word vectors, the word-to-vector process is free from manual intervention, the cost for manually constructing and selecting features by use of a conventional method is decreased, and the classification effect is better than that of the conventional classification method.

Description

technical field [0001] The invention relates to the field of information retrieval, in particular to a method and system for emotion classification. Background technique [0002] With the rapid development of Internet technology and the emergence of social platforms such as Twitter, Facebook, and Weibo, people can express their opinions and comments on social events and corporate products on the Internet, and different users can follow and share with each other. These social network data contain a large amount of emotional information of network users. By analyzing these data, we can grasp the trend of public opinion of the network crowd, thus providing an effective basis for the government and enterprises to make decisions. Among them, sentiment analysis is an important basis for public opinion analysis. Its main task is to determine its emotional category based on network text data by analyzing the emotional polarity and semantic information contained in it, which is usual...
