Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0027] Such as figure 1 As shown, the present invention provides a kind of method that utilizes emoticon to carry out emotion tendency classification to microblog, comprises:

[0028] Step 1. Create neutral emotion set, negative emotion set and positive emotion set, specifically:

[0029] a. Select 624 emoticons used more than 200,000 times in Sina Weibo in 2011 and 2012 as seed emoticons, and extract n microblogs containing this emoticon for each seed emoticon selected As the first microblog set, each first microblog set contains 10,000 first microblogs, and the top 100 words with reproducibility are extracted from the text of 624×10,000 first microblogs as high-frequency words. Each seed emoticon selects 100 microblogs containing this emoticon as the second microblog set,...

Abstract

The invention discloses a method for performing emotional tendency classification to microblog by using emoticons. The method comprises the following steps: building a neutral emotion set, a passive emotion set and a positive emotion set; building a neutral emotion Bayes classifier by using the neutral emotion set, the passive emotion set and the positive emotion set; building a polar emotion Bayes emotion classifier by using the passive emotion set and the positive emotion set; performing emotion classification to the microblog by using the neutral emotion Bayes classifier and the polar emotion Bayes classifier. According to the method for performing emotional tendency classification to microblog by using emoticons, two sections of classification is built, namely, building the neutral emotion classifier to remove the microblog with neutral emotion, and building the polar emotion classifier to divide the microblog with the polar emotion into the passive emotion and the positive emotion; the classifier is rapid in classifying speed, small in occupied space and robust; attitude of people to current hot topics or events and emotion of net citizens can be accurately understood through the microblog, so that the method for performing emotional tendency classification to microblog by using emoticons has important help for social scientific research and survey.
