Abstract

At present, the use of public opinion analysis method to explore the feelings of users in comments has become one of the hot research topics, and has been applied in many business and public management fields, such as movie box office, stock trend prediction, public opinion monitoring in power sector, etc. Data mining and analysis based on big data technology is increasingly demanding, and the logical relationship of data processing is increasingly complex. How to analyze and mine network public opinion information in heterogeneous data environment has become a big challenge in data management, application and value mining. This paper summarizes and compares several mainstream public opinion analysis methods and their applications, including unsupervised public opinion analysis method and supervised public opinion analysis method, and introduces the application scenarios related to public opinion analysis. A network public opinion analysis system model based on big data technology is designed to provide important data support for network public opinion monitoring.
