Geographic Networks: Contextualizing Relationships in Space

Perhaps the most famous visualizations from Culturomics 2.0 were the geographic networks that illustrated how the geography of the world is interconnected through the eyes of the news media. Geographically-situated networks, in which nodes are placed in space at their actual geographic locations, offer an incredibly rich new analytic framework that blends spatial and non-spatial […]

Timelines of Countries and of Themes

One of the first requests from early previews of the Timeline Visualization tool was the ability to plot countries and themes in a similar way, to make it possible to observe temporal correlations. Countries often exhibit complex temporal interplays in which events or views in one country spill over into neighboring or culturally proximate countries. […]

Timelining Tone: Visualizing Emotional Timelines

Emotion has become an increasingly powerful lens through which to explore the world, as a growing literature demonstrates the ability to extract powerful latent cues from our daily discourse and the connection of those cues to physical action. For example, few countries have collapsed in the midst of skyrocketing popular support for their leadership or […]

Visualizing the Timelines of Conflict

The concept of time is at once one of the most basic dimensions through which to understand and visualize conflict, yet simultaneously it is one of the more difficult to represent concisely at high resolution. Representing daily change over 35 years requires arraying more than 12,700 data points in a single one-dimensional linear display. Traditionally […]

Heatmapping Hotspots: The New Heatmapper Visualization

One of the most-requested features for the new GDELT Analytics Service has been the addition of GIS-friendly export file formats and especially creation of a “heatmap” visualization capability. Thus, without further ado we present the new GDELT Event and Global Knowledge Graph Heatmapper tools!   (Click the image above to view the interactive heatmap).

Expediting Extraction and Exporting: GDELT Event and GKG Exporter Tools

The massive size of GDELT’s data archives can make it difficult to extract just the subset of data you need for a given visualization or analysis. For example, trying to map all attacks against a certain ethnic group in Nigeria over the last 35 years requires examining over a quarter-billion records, each of which records […]

Introducing the GDELT Analysis Service

Today we are extraordinarily excited to announce a spectacular new addition to the GDELT family: the GDELT Analysis Service!

Mapping Violence and Protests in Nigeria

As the world's media outlets run round-the-clock coverage of masked soldiers facing off against besieged Ukrainian military outposts in Crimea, the rest of the world has largely been drowned out. Few, for example, have likely followed the events in Nigeria, where Boko Haram has executed 59 children in an attack on a boarding school and […]

Mapping Spatial Trends in Violence in Afghanistan Using GIS

As GDELT is increasingly finding pilot use in operational trend detection contexts, we have been receiving a growing number of requests from users integrating it with professional GIS software like ESRI’s ArcGIS platform. Users are looking to combine GDELT with other GIS datasets, perform various types of spatial analyses, or to overlay it onto thematic […]

Using GDELT for Atrocity Early Warning

The rising use of GDELT in contexts such as conflict early warning and emerging atrocities forecasting brings with it the need for new methodologies, mindsets, and techniques for working with this "big data" study of human society, the functioning of the global news media system, and the underlying technologies that make GDELT's "societal scale" codification […]

A Visualization of Protests in the Americas, 2007-2013

The global economic downturn, which began roughly in 2007, has sparked new debates on the future of global capitalism around the world.
