Nested Named Entity Recognition with Span-level Graphs 具有span级图的嵌套命名实体识别 acl 2022 原文地址:2022.acl-long.63.pdf (aclanthology.org) Abstract 基于span的方法(span-based)在处理嵌套NER的问题上很有潜力,但是正负例的大量重叠会使得其退化。此外,泛化能力在嵌套NER上也很重要,因为测试集中的大部...

过去的命名实体识别主要考虑的是扁平命名实体识别(flat NER)。近年来有一些工作考虑了实体之间可能存在嵌套关系,由此对应地提出嵌套命名实体识别(nested NER)这一新任务。 具体来说,如下图(1)所示:“上海市红十字会”就是一个典型的包含嵌套命名实体的例子。其中“上海市”是地名、“红十字会”是组织名、“上海市红...
Named-Entity Recognition (NER) is a core part of information extraction. India is a multilingual country with 23 official languages and over 122 major languages, where a significant population is multilingual. Most of the conversations, whether online or in person, involve code-switching and transl...
Nested Named Entity Recognition Using Multilayer Recurrent Neural NetworksMany named entities are embedded in others, but current models just only focus on recognizing entities at the top-level. In this paper, we proposed two approaches for the nested named entity......

Named Entity Recognition (NER) is fundamental in natural language processing, involving identifying entity spans and types within a sentence. Nested NER contains other entities, which pose a significant challenge, especially pronounced in the domain of medical-named entities due to intricate nesting patt...
