About This Webinar
This presentation focuses on the use of social media for computational propaganda and other nefarious uses such as Echo Chambers targeting Twitter. The presentation will also include a demonstration of Python based GEO-OSINT application to acquire LIVE open-source intelligence from tweets and the associated images, videos, and translated emojis from geographically bounded areas anywhere in the world. As you may know Twitter routinely removes tweets and images from their platform based on policy violations and other influences. By acquiring them as they occur provides both timely access to live events, as well as the ability to preserve future redacted information. Chet and Mike will provide details of the approach including examples of Python code along with a live demonstration.
