Abstract
This contribution summarizes our research work in the context of social media analysis and crisis management. It focuses on the detection of sub-events, which are special hotspots of a crisis that emergency management teams must be aware of. We give an overview on our investigations done in the offline sub-event detection area and summarize the corresponding evaluation results. We also provide some insights into our current work on online sub-event detection (i.e., online features selection and incremental clustering).
