With reports of high rates of unreported crimes in South Africa, there is a need for additional information beyond official crime statistics that are made available to the general public annually. South Africa is reported to have one of the highest crime rates in the world and as such, crime has become the most difficult challenge faced by the South African population on a daily basis. At the same time South Africa, though a developing country, is in the unique position of having a highly active social media presence with approximately 22% of the population having active social media accounts. Notably, social media platforms have enabled the sharing of incident information such as car accidents, car theft and missing persons. In this project, we developed a framework that employs social media (twitter and Facebook) content to identify public safety incidents to assist in gathering insights to either add to law enforcement cache of tools for a better understanding of where to deliver protective services or to provide point data for crime detection on a daily basis.
The DSIDE internship programme has been the most rewarding academic experience for us. We continue to apply the analytical as well as project management skills and work ethic that our amazing mentors instilled in us in our various fields. We hope many more students can have the opportunity to experience this.
