This workshop is an introduction to open source data analysis used in the context of nonproliferation and terrorism studies. The workshop will have both policy lectures as well as hands-on training in the computer lab. The workshop is designed as an overview of data analysis techniques and open source tools with an emphasis on practical application. Students will apply structured intelligence analysis methods using deep web searching, crowdsourcing, text and data mining, and network analysis. The workshop includes a final project where students will gather actual data, analyze it with techniques and tools learned, and present their results.
