Named entity recognition (NER) is the task of tagging entities in text with their corresponding type. Approaches typically use BIO notation, which differentiates the beginning (B) and the inside (I) of entities. O is used for non-entity tokens. ...
自然语言处理(NLP)是人工智能领域的一个重要分支,旨在让计算机理解、生成和处理人类语言。在过去的几年里,NLP 领域取得了显著的进展,这主要归功于深度学习技术的迅猛发展。深度学习技术为 NLP 提供了强大的表示学习和模型训练方法,使得 NLP 任务的性能得到了显著提高。 在NLP 领域中,实体识别(Named Entity Recognitio...
自从MUC6以来,人们对NER的兴趣越来越高,各种科学事件(例如CoNLL03 ,ACE ,IREX 和TREC Entity Track )都为此主题投入了很多精力 3) 应用场景 命名实体识别(NER)的任务是识别文本中属于预定义语义类型(如人、位置、组织等)的刚性指示器的提及。NER不仅充当信息抽取(IE)的独立工具,而且还在各种自然语言处理(NLP)应用...
NLP学习笔记12---信息抽取(Information Extraction 简称IE)、命名实体识别(Named Entity Recognition 简称NER) 1.信息抽取介绍 从非结构化数据中,抽取数据。 非结构化数据包括图片、文本、视频、音频等内容,提取特征输入到model中,而结构化数据类似于数据库中的一个个字段。 信息抽取主要包括两个部分:一个是抽取实体,...
论文:Named Entity Recognition as Dependency Parsing代码:juntaoy/biaffine-ner Abstract and Introduction 传统的ner任务大多为Flat NER,没有考虑到Nested NER(嵌套实体:一个token可能分别拥有两个不同的类型)的情况。 比如北京大学中的北同时属于「B-Location」,也属于「B-Organization」;而京也拥有「I-Location」...

Named Entity Recognition is one of the information retrieval techniques which classifies a particular word or a phrase in its appropriate class. NER can thus, also be used in extracting entities from legal documents, which would help in providing an effective way to represent these documents. This...
Inspired by the concept of content-addressable retrieval from cognitive science, we propose a novel fragment-based Chinese named entity recognition (NER) model augmented with a lexicon-based memory in which both character-level and word-level features ar

A Survey on Deep Learning for Named Entity Recognition命名实体识别综述 1.命名实体识别的定义 命名实体识别就是从文本中识别出特定的语法定义类型如人名、地名、组织名等内容。 2.命名实体识别的意义 命名实体识别不仅是信息抽取的一个独立工具,同时它在其他的NLP任务中也有很重要的作用。如文本理解、信息复原、自...
