1 命名实体识别 命名实体识别(Named Entity Recognition,NER)是信息抽取、信息检索、意见挖掘以及问答系统等自然语言处理任务中不可或缺的关键技术,其主要任务是识别出文本中表示命名实体的成分,包括人名、地名、日期等并加以归类,因而也被称作命名实体识别和分类(Named Entity Recognition and Classification,NERC)。 NER...
实体命名识别(Named Entity Recognition, NER)是信息提取中的一个重要任务,其目标是从文本中识别出特定类型的实体,比如人名、地名、组织机构等。本文将带你一步一步实现一个简单的NER模型,使用Python和常用的库。我们将通过表格来展示整个流程,并提供每一步需要的代码,同时进行详细的注释。 流程概述 以下是实现NER的...

命名实体识别(Named Entity Recognition,简称NER)是一个有监督的系列标注任务,又称作“专名识别”,是指识别文本中具有特定意义的实体,主要包括人名、地名、机构名、时间、专有名词等关键信息。 通过NER识别出一些关键的人名、地名就可以很方便地提取出“某人去哪里,做什么事的信息”,很方便信息提取、问答系统等任务。

Furthermore, ...
seqeval is a Python framework for sequence labeling evaluation. seqeval can evaluate the performance of chunking tasks such as named-entity recognition, part-of-speech tagging, semantic role labeling and so on. This is well-tested by using the Perl scriptconlleval, which can be used for measuring...
