A system and method for real-time monitoring of geographical location of network public opinion

Abstract

The invention discloses an online public opinion geographical location real time monitoring system and a method. Topic key word lists are obtained through unifying acquiring methods of microblogs, blogs and forum data and analyzing and removing repeat of similarities; geographical locations and time information are extracted using the technology of front, back and boundary cutting, front, back and boundary are achieved through website structures which are built in advance, and the situation that procedures conduct adjustment according to the website structure is avoided; and data are obtained according to every keyword and the data are processed, spread situations are restored dynamically on a geographic information system (GIS) geographic model, and net citizen number is analyzed. Mapping of network environment and real environment is achieved through transforming network geographic locations into longitude and latitude coordinates, and data are input into GIS software in batches according time to achieve dynamic demonstration spread processes.
