WNUT 2017 (WNUT 2017 Emerging and Rare entity recognition)

Introduced by Leon Derczynski et al. in Results of the WNUT2017 Shared Task on Novel and Emerging Entity Recognition1 Sep 2017 archive 2025-07-28

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 summarisation), 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 entity kktny hard to detect and resolve. This task will evaluate the ability to detect and classify novel, emerging, singleton named entities in noisy text.

The goal of this task is to provide a definition of emerging and of rare entities, and based on that, also datasets for detecting these entities.

21 shown of 21 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 127. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
