Description

technical field [0001] The invention belongs to the fields of data mining and information retrieval, and in particular relates to a Chinese text emotion analysis device and method. Background technique [0002] Nowadays, the Internet has become an indispensable part of people's lives. People can not only receive information from the Internet, but also post their views and opinions on a certain event, person or product on the Internet. These network information reflect the emotional tendency of the public, and it will be of great benefit if the emotional information contained in it can be excavated from the numerous texts. [0003] However, precisely because of the popularity of the Internet, a large number of Chinese texts, such as some comments, appear on the Internet. Most of these texts are disorganized and unstructured. It is almost impossible to judge emotional tendencies only by artificial methods. [0004] Therefore, sentiment analysis technology has important resear...
