我们介绍ReDites，一个实时事件检测、跟踪、监控和可视化系统。它的目的是帮助信息分析师理解和探索复杂的事件，因为他们在世界上展开。从Twitter流中自动检测事件。然后，那些被归类为与安全相关的信息将被跟踪、定位、汇总并可视化，以供最终用户使用。此外，该系统跟踪事件中情绪的变化，发出可能的爆发点或缓和信号。我们使用2013年9月Westgate枪击事件的扩展用例来演示ReDites的功能。通过对系统延迟的评估，我们还展示了丰富的事件可供用户在事件发生后的几秒钟内进行探索。
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.
