Event detection

Summary

Event detection is a problem of extracting discrete events usually from a stream of time-stamped information. Approaches usually aim to group documents belonging to the same event into a single cluster.

A similar line of research existed in the Information Retrieval community in the late 90s to early 2000s called Topic Detection and Tracking, but the topic has seen a revival of interest since the mass availability of time-stamped social data such as Twitter streams.
