Abstract

The invention discloses an emotion dictionary expansion method and an emotion polarity analysis method based on an SOPMI algorithm. The method comprises the following steps: collecting public opinion text data; collecting positive reference words and negative reference words as seed words; utilizing an SOPMI algorithm to calculate sentiment scores of the words and generating a sentiment dictionary; performing word segmentation on the text data by utilizing jieba, and extracting nouns and verbs in the text data; and scoring the text information by using the score weighting of the nouns and the verbs. The problem that most sentiment polarity analysis intelligence cannot generate a special sentiment dictionary of an own project based on an existing sentiment dictionary is solved.

Description

technical field [0001] The invention relates to the technical fields of machine learning and text analysis, and more specifically relates to a method for expanding a sentiment dictionary based on a SOPMI algorithm and a method for analyzing sentiment polarity. Background technique [0002] With the development and progress of society, the diversification of media, the rapid development of the network, the popularity of mobile terminals, and the widespread use of microblogs and forums, a large amount of information is circulated in the network in various ways every day. After filtering spam , still unable to evaluate the information effectively. Whether it is positive or negative information, high-quality and low-quality information can be distinguished by text scoring. On the one hand, it can facilitate the analysis of public opinion by enterprises or governments, and on the other hand, it can gain a wider understanding of the word-of-mouth of products among users.
