This shared task focuses on identifying unusual, previously-unseen entities in the context of emerging discussions. Named entities form the basis of many modern approaches to other tasks (like event clustering and summarization), but recall on them is a real problem in noisy text -even among annotators. This drop tends to be due to novel entities and surface forms. Take for example the tweet "so.. kktny in 30 mins?!" -even human experts find the entity kktny hard to detect and resolve. The goal

The task as described in this paper evaluated the ability of participating entries to detect and classify novel and emerging named entities in noisy text.
