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.
