Since 2015, the DS3 laboratory has been developing a comprehensive dataset of millions of geolocated tweets for the continental U.S. This database allows our research team to search for keywords of topics for a variety of research projects. This database includes meta-data attributes for both Twitter users and tweets allowing our team to conduct advanced analytics of the data. We entitled this project the Human Sensor Project with the idea that human activities, such as aggregate thoughts, behaviors, and collective actions, can be sensed online through an analysis of Twitter activity and approximate locations associated with tweets. Our team to date has used the data to study health and natural disasters, such as Hurricane Sandy, the Flint Water Crisis, COVID-19, as well as other societal issues such as rape culture, victim blaming, and reactions to crime cases.
