Could we predict the kidnapping of Nigerian girls?

This article by Harvard NTL, which ran the USAID / Humanity United Tech Challenge for Atrocity Prevention, discusses how the results of the top models could have potentially given critical state-level insight into elevated risk of civilian atrocities like the kidnapping in Borno State.

Refocusing Intelligence on Analysis

Kalev's latest Foreign Policy column discusses the need to refocus the intelligence process on analysis rather than collection – how do we better understand the rich array of open public indicators from the news media, social media, and other data streams? Read the Full Article For those interested in this topic, Josh Kerbel, Chief Analytic Methodologist […]

Kalev Speaks at National Defense University Forum

GDELT creator Kalev Leetaru spoke at National Defense University today at a forum organized by the Center for Technology and National Security Policy and the Deputy Assistant Secretary of Defense for Africa.  He presented on how GDELT can be used to visualize and understand macro-level patterns in conflict across the continent.

Kalev Speaks at Data Community DC

GDELT creator Kalev Leetaru spoke to a packed house at Data Community DC's April meeting on his lessons learned from working at the frontiers of big data. Talk Announcement. Summary Writeup.

GDELT At GEOINT 2014 on GEOINT Foreword Panel

We were incredibly honored to present an overview of GDELT today on the GEOINT Foreward Panel on Human Geography at GEOINT 2013/2014, alongside Geographer of the United States Dr Lee Schwartz (Department of State), Mike Williams (US Central Command), and Brian Hagan (National Geospatial Intelligence Agency).  We were unable to be there in person, so Mike Williams graciously […]

SBP 2014 Grand Data Challenge Winner

Its always incredibly exciting to see all of the different ways that GDELT is being applied and it is especially compelling to see some of the incredibly sophisticated analytic techniques that are being applied to GDELT that take advantage of its unique size, scale, and richness. This year's International Social Computing, Behavioral-Cultural Modeling and Prediction […]

From Big Data to Global Diplomacy: Today and Tomorrow

Today Kalev's Yahoo! Conference was held Georgetown University, titled "From Big Data to Global Diplomacy: Today and Tomorrow" and featuring presentations from Will Mayo of GNIP and Noel Dickover of the US Institute of Peace and a three-way panel discussion on the future of how big data is permanently reshaping the landscape of global diplomacy. Learn […]

Working with GDELT in Python: A Quick Tutorial

Python has become an increasingly popular language for rapidly working with large datasets.  James Houghton has a great quick tutorial for loading and working with the GDELT event database in Python. Read the tutorial.

TimeMapper: Rwanda

With today being the 20th anniversary of the genocide in Rwanda, we've received a number of requests for visualizations and insights that show what “big data” analysis of the news media can tell us about the conflict. Similar to the visualization of Nigeria in 2014, we’ve created a TimeMapper visualization, courtesy of the GDELT Analysis […]

Understanding Megacities

Megacities will play an outsized role in global politics and national stability over the coming decades with some estimates suggesting nearly three quarters of the world’s inhabitants will be living in such urban environments by 2050. From water access to sanitation, flooding to healthcare, communications to transportation, megacities present a host of unique challenges, including […]

Networking The World’s Newsmakers

Perhaps one of the GDELT Analysis Service’s most eagerly-awaited new visualizations is its Global Knowledge Graph Network Visualizer, which allows you to rapidly construct network visualizations of the people, organizations, locations, and themes undergirding global society. Delivered to your inbox is an interactive browser-based network visualization, a spreadsheet of “centrality” and “influencer” rankings, and even […]

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! This new cloud-based service allows you to visualize, analyze, explore, and export both the GDELT Event Database and GDELT Global Knowledge Graph completely from your web browser, with no technical experience or expertise whatsoever required. You […]
