说到NER,是绕不开BERT+CRF的,根据本人的经验,BERT+CRF就算不是你当前数据集的SOTA,也与SOTA相差不大了,但考虑到 更好的效果:CRF虽然引入了无向图,但只约束了相连结点之间的关联,并没有从全局出发来考虑问题 更复杂的业务场景:如Flat NER到Nested NER、不连续NER等复杂业务场景的不断涌现,CRF是否还能优雅地解...
Fast-Bert will support both multi-class and multi-label text classification for the following and in due course, it will support other NLU tasks such as Named Entity Recognition, Question Answering and Custom Corpus fine-tuning. BERT(from Google) released with the paperBERT: Pre-training of Dee...

Hence, the pre-trained BERT model can be fine-tuned with just one additional output layer to create state-of-the-art models for a wide range of tasks, such as named entity recognition (NER) and sentiment analysis (SA) (Leow et al., 2021; Pota et al., 2021; Yang et al., 2022)....
The second stage was to apply the pre-trained language model to down-stream tasks such as NER. Different word embeddings can be obtained for the same word in different contexts. Due to the success of these models across a variety of NLP tasks, leveraging unsupervised pre-training has become ...
为评估DialogueBERT在下游对话任务中的应用,作者在意图识别(IntR)、情感识别(EmoR)、命名实体识别(NER)三个任务上进行了实验。 数据: 模型在7000万对话数据上进行了预训练,该对话数据来自于京东内部真实的电子商务场景中的用户和客服人员的对话,平均每段对话有8.59个话语。
Bert-ChineseNER Introduction 该项目是基于谷歌开源的BERT预训练模型,在中文NER任务上进行fine-tune。 Datasets & Model 训练本模型的主要标记数据,来自于zjy-usas的ChineseNER项目。本项目在原本的BiLSTM+CRF的框架前,添加了BERT模型作为embedding的特征获取层,预训练的中文BERT模型及代码来自于Google Research的bert。

In 2015, Santos and Guimaraes (2015) proposed a language-independent NER system that used automatically learned features only. In 2020, they evolved the char-CNN based on evolutionary deep learning techniques(Londt et al. 2020), which used word-level and character-level representations to perform...
