We use news media attention from the Global Data of Events, Location and Tone (GDELT) database, as a proxy for estimating Global Peace Index (GPI), to complement the knowledge obtained from the traditional data sources, and overcome their limitations. Considering that GDELT is updated daily, and it is a free access database, it can contribute to the estimation of GPI at a higher frequency, i.e. at a monthly level, as compared to the official GPI which is updated at a yearly level. Besides, GPI though GDELT is produced at a low cost, and in a time-efficient way, as compared to the traditional methodology.
