基于半監(jiān)督協(xié)同訓練的文本情感分類研究
[Abstract]:With the rapid development of Web2.0, a large number of user-generated content (User Generated Content). Have been generated on the Internet. These user-generated content contains a large amount of useful emotional information, which is of great value to user decision-making and product improvement in enterprises. Therefore, how to use text emotion classification technology to mine the emotional information in the massive user-generated content has become a hot issue in academia and industry. Although the text affective classification method based on machine learning has achieved good results, it takes a lot of manpower to obtain labeled samples in practical applications. On the contrary, it is very easy to obtain unlabeled samples. Therefore, how to use a small number of labeled samples and a large number of unlabeled samples for text affective classification has become an urgent problem. In order to solve the problem of using unlabeled samples in text affective classification, semi-supervised cooperative training method is introduced into text affective classification. Firstly, this study analyzes the current situation of text affective classification and semi-supervised learning, and clarifies the current research issues and future research directions. Secondly, this study systematically studies the basic theories of text emotion classification and semi-supervised learning, analyzes the main tasks of text emotion classification, the main methods of text emotion classification, and the basic assumptions of semi-supervised learning. The effectiveness of semi-supervised learning and the main methods of semi-supervised learning and other basic theories. Then, based on this, the text emotion classification method based on semi-supervised cooperative training is studied. Considering that the current research has paid little attention to the influence of data distribution on text affective classification, this study constructs the text emotional classification model based on IDSSL under the condition of data distribution equilibrium from the two angles of data distribution equilibrium or not. And the text emotion classification model based on mixed strategy under the condition of unbalanced data distribution. Finally, the text emotion classification method based on semi-supervised cooperative training is introduced into the practical application, and two practical application scenarios, e-commerce and medical social media, are selected. The validity of two kinds of text emotion classification methods based on semi-supervised cooperative training is tested. The experimental results show that the proposed method has better results under different data distribution conditions, thus validating the effectiveness of the proposed method. Through this research, on the one hand, the semi-supervised learning method is introduced into the text affective classification problem, which expands the basic theory of text affective classification and semi-supervised learning. Based on this, a text emotion classification model based on semi-supervised cooperative training is constructed. On the other hand, the text emotion classification model based on semi-supervised cooperative training is applied to practical problems, which extends the application of text emotion classification and semi-supervised learning.
