positive和negative example:因为support example只包含一个实体,因此在训练时需要添加negative example。例如如果当前positive entity type为“CITY”,则可以从support set中挑选entity type不为“CITY”的example作为negative example。因此相对于positive example,negative example表示的是不包含任何实体。 在训练时,是在source...
命名实体识别(Named Entity Recognition,NER),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 专有名词等 NER是: 信息提取 问答系统 句法分析 机器翻译 面向Semantic Web的元数据标注等 应用领域的重要基础工具,在自然语言处理技术走向实用化的过程中占有重要的地位。 例如在搜索场...
Named entity recognition is described, for example, to detect an instance of a named entity in a web page and classify the named entity as being an organization or other predefined class. In various examples, named entity recognition results are used to augment text from which the named entity...
实验结果表明 NSP对大多数数据集都有提升,尤其5-shot。prototype-based method 仅仅对labeled数据非常少的数据管用(entity type和example都很少),在fine-tune之前加入self-training是useful的,三种方式结合往往能取得不错的结果。 5.3 Comparison with SoTA Methods ...
Named entity recognition (NER) is a component of natural language processing (NLP) that identifies predefined categories of objects in a body of text.
NER example Consider the sentence: "Mary from the HR department said that The Ritz London was a great hotel option to stay in London." NER performed on the sentence using the displaCy Named Entity Visualizer. In this sentence: "Mary" is labeled as PERSON, indicating that it is an entity ...
然而这样会产生更多低质量的增强样本,为此,我们提出meta reweighting策略来控制增强样本的质量。同时,使用example reweighting机制可以很自然的将两种方法结合在一起。实验表明,在小样本场景下,本文提出的方法可以有效提升数据自增强方法的效果,在全监督场景下本文的方法仍然有效。
