The GDELT project is a free global news media database that provides data support for re-search on global issues in the humanities and social sciences.After the introduction of the GDELT project,the data acquisition methods,and the application areas and problems of the data;taking the Event database as an example,selecting its field indicators,to construct its basic variables;selecting the research methods and the refinement of mathematical ideas,comes the discussion and outlook of the research.The current re-search problem is"multi-faceted"and can be divided into three areas:metadata processing and parsing,social hotspot mining,and international relations research,mostly with the help of classical methods and mathematical ideas to solve hotspot problems.Future research should(1)break down disciplinary barriers,and integrate and collaborate with multiple disciplines,(2)dig deeper again,and explore new applications of GDELT project data,(3)improve the data sharing platform,add more search and query modules,and in-tegrate data from multiple parties,to build a local real-time monitoring and early warning platform,so as to fully understand data limitations and use data scientifically.
