Deploying Social Media Data to Inform Gun Policy
This study will investigate the use of data from social media posts to measure gun-related outcomes in cities or states, and improve the data available to support rigorous gun policy research.
This project seeks to improve the data available to understand gun-related outcomes and support rigorous gun policy research through the novel use of social media data.
- Develop estimates of gun-related mortality and benchmark against estimates based on data from the National Vital Statistics Systems and the Centers for Disease Control.
- Develop algorithms to predict gun ownership status.
- Use the large repository of Twitter data housed at Georgetown’s Massive Data Institute (MDI) as primary data source.
- Collect additional social media data using keywords and hashtags related to gun violence.
- Conduct a manual review of gun violence/mortality-related tweets and code each tweet as identifying a gun-related homicide, gun-related suicide, or any gun-related death.
- Using manually labelled data as training data, develop a classifier to identify tweets discussing gun-related deaths.
- Develop a second classifier that determines type of gun death.
- Develop predictive algorithms for gun ownership status from Twitter posts.
- Conduct validation testing throughout the study.
Build a foundation for understanding for how social media data may be used—alone or with other data resources—to improve gun policy research.
