Abstract
The sentiment analysis system is one of the most classic applications in natural language processing and enduring. The development of the mobile Internet has greatly increased people's participation, and everyone can make their own comments on social media platforms such as Weibo. Through public opinion mining and emotional analysis of text information, a rich potential value of information can be obtained. However, in the face of a large number of comment data, how is it more convenient for public opinion workers to see the whole picture and take timely measures? This is the practical problem to be addressed in this article. The main work of this article is to build a public opinion emotional analysis system about Jiangsu Police Institute, to realize the emotional analysis of the comments related to Jiangsu Police Institute in Weibo and post bar. Then related workers are able to screen out the comments of negative emotions. The experimental dataset in this article is a training dataset composed of positive and negative reviews selected from JD commodity reviews, and the test data are random reviews selected from the microblog of Jiangsu Police Institute. This article details the processing of the Chinese comment text dataset. Because Chinese text is involved, the data is first partitioned using the jieba participle. After the data pre-processing, we input the processed data into the Word2Vec model, and set the relevant parameters according to the formatting rules of the word2vec, so that the dataset of text can be quantized to facilitate code learning.
