Real-Time Detection, Tracking and Monitoring of Discovered Events in Social Media
We introduce ReDites, a system for realtime event detection, tracking, monitoring
and visualisation. It is designed to assist Information Analysts in understanding and exploring complex events as they
unfold in the world. Events are automatically detected from the Twitter stream.
Then those that are categorised as being security-relevant are tracked, geolocated, summarised and visualised for the
end-user. Furthermore, the system tracks
changes in emotions over events, signalling possible ﬂashpoints or abatement.
We demonstrate the capabilities of ReDites using an extended use case from the
September 2013 Westgate shooting incident. Through an evaluation of system latencies, we also show that enriched events
are made available for users to explore
within seconds of that event occurring.
