One of the leading innovators of the internet era, for more than 20 years Kalev H. Leetaru has been at the forefront of reimagining how we understand our world through some of largest datasets and computing platforms on the planet. His landmark studies have profoundly reshaped the way we use data in the study of human society and even redefined what "big data" is, leading Der Speigel to call him "one of the superstars of the new discipline".
One of Foreign Policy Magazine's Top 100 Global Thinkers of 2013 and a Council Member of the World Economic Forum's Global Agenda Council on the Future of Government, and a past fellow and adjunct faculty at Georgetown University's Edmund A. Walsh School of Foreign Service, Kalev's work has been featured in publications from Nature to the New York Times, along with the press of more than 100 nations. In 2011 The Economist selected his Culturomics 2.0 study as one of just five science discoveries deemed the most significant developments of 2011, while the following year HPCWire awarded him the Editor's Choice Award for Edge HPC (High Performance Computing) "representing the highest level of honor and recognition given to the thought leaders in the HPC community" and in 2013 noted "his research helped usher in the era of petascale humanities", while later that year his work on Twitter was recognized by Harvard's Neiman Lab as the top social media study of 2013.
From the first study of the geography of social media, which set off the arms race to map Twitter, to the first television show live-controlled by the audience's emotional response to its characters, which set numerous records for social engagement with a television show, from the largest deployment of sentiment analysis (more than 2,300 emotions and themes applied to all accessible global news), to the first deployment of whole-of-earth realtime machine translation (live translating all accessible global news media in 65 languages), from the first realtime mapping of emotion in social media, to the creation of one of the largest historical image collections from half a billion pages of digitized books spanning 500 years and 1,000 libraries, from the first full-scale maps of the geography and emotion of television news, to the first socio-cultural analysis of the world's academic literature, spanning 50 years and more than 21 billion words, from the first at-scale studies of the entire Internet Archive's web collection, exploring its 1.7 billion PDFs, to the pioneering use of emotion in forecasting conflict, and the largest global monitoring platform, Kalev's work has fundamentally redefined how we think about information at scale and how we define the boundaries of the "big data" era.
Today Kalev works with organizations from the US Government to NBC Universal, the World Bank to the US Institute of Peace, the Internet Archive to the United Nations, to a myriad government agencies, corporations, and NGOs across the globe to reimagine how we use data to understand the world around us at scales and in ways never before imagined.
A Legacy of Innovation
Since founding his first internet startup in 1995 while still in eighth grade (just a year after the debut of the modern web browser), Kalev's career has spanned 20 years of landmark studies reshaping fields from journalism to history, social media to the study of society itself.
20 Years of Reimagining Our World Through Data
Kalev co-founded his first web company in 1995, becoming one of the early pioneers of the dot-com era while still in middle school. By the time he was a junior in high school, Kalev's company had established its own international reseller program, with sales coming in from throughout the globe. As a senior in high school he became one of the first high school interns at the National Center for Supercomputing Applications, where he co-led the creation of one of the earliest "web scale" web mining platforms to understand evolving global trends. His undergraduate research alone yielded three issued US patents anticipating the rise of cloud computing that have been cited by 51 US patents from companies ranging from Apple and Amazon to Google and Oracle, while he amassed more than 50 University Invention Disclosures, placing him among the University's most prolific. Today his GDELT Project is one of the largest global open monitoring platforms on the planet, becoming the gold standard for computationally exploring human society.
Below are just a few of Kalev's most recent projects.
