Dataset Card for "wnut_17" Dataset Summary WNUT 17: Emerging and Rare entity recognition 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… See the full description on the dataset page: https://huggingface.co/datasets/Kriyans/ner.数据集卡片——“wnut_17” 数据集概要 WNUT 17：新兴与罕见实体识别 本共享任务专注于在新兴讨论的语境中识别不寻常、先前未见过的实体。 命名实体是许多现代方法（如事件聚类和摘要）的基础，但在噪声文本中对其的召回率是一个实际问题——即使在标注员中也是如此。这种下降趋势往往归因于新实体和表面形式。更多详情请参阅数据集页面：https://huggingface.co/datasets/Kriyans/ner。
