【摘要】 为了让学生用所学算法知识解决实际问题,设计了一个基于机器学习算法的舆情分析案例。以电影《战狼2》的影评分析为例,通过词云图分析数据的一般规律,然后利用时间序列和文本聚类方法对舆情进行分析。分析结果显示,观众的情感倾向及关注度短期内不会有较大的变化,且与具体的情景息息相关。更多还原

【Abstract】 In order to teach students to solve practical problems with the knowledge of algorithm, a public opinion analysis case based on machine learning algorithm is designed. By taking the movie "Wolf Warriors 2" as an example, this paper analyses the general rules of data through the word nephogram, and then uses time series and text clustering method to analyze public opinion. The analysis results show that the audience’s emotional orientation and attention will not change significantly in the short term and is closely related to the specific situation.更多还原
