Named Entity Recognition

94 papers with code · Natural Language Processing

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.

Example:

A Smoother Way to Train Structured Prediction Models

NeurIPS 2018 krishnap25/casimir

We present a framework to train a structured prediction model by performing smoothing on the inference algorithm it builds upon. The experimental results show that the proposed framework allows us to build upon efficient inference algorithms to develop large-scale optimization algorithms for structured prediction which can achieve competitive performance on the two real-world problems.

Multilingual NER Transfer for Low-resource Languages

1 Feb 2019afshinrahimi/mmner

In massively multilingual transfer NLP models over many source languages are applied to a low-resource target language. In contrast to most prior work, which use a single model or a small handful, we consider many such models, which raises the critical problem of poor transfer, particularly from distant languages.

BioBERT: a pre-trained biomedical language representation model for biomedical text mining

25 Jan 2019naver/biobert-pretrained

Biomedical text mining is becoming increasingly important as the number of biomedical documents rapidly grows. However, as deep learning models require a large amount of training data, applying deep learning to biomedical text mining is often unsuccessful due to the lack of training data in biomedical fields.

A Tweet Dataset Annotated for Named Entity Recognition and Stance Detection

15 Jan 2019dkucuk/Tweet-Dataset-NER-SD

Annotated datasets in different domains are critical for many supervised learning-based solutions to related problems and for the evaluation of the proposed solutions. Topics in natural language processing (NLP) similarly require annotated datasets to be used for such purposes.

Few-shot classification in Named Entity Recognition Task

For many natural language processing (NLP) tasks the amount of annotated data is limited. This urges a need to apply semi-supervised learning techniques, such as transfer learning or meta-learning.

Combining neural and knowledge-based approaches to Named Entity Recognition in Polish

26 Nov 2018sdadas/polish-nlp-resources

Named entity recognition (NER) is one of the tasks in natural language processing that can greatly benefit from the use of external knowledge sources. We propose a named entity recognition framework composed of knowledge-based feature extractors and a deep learning model including contextual word embeddings, long short-term memory (LSTM) layers and conditional random fields (CRF) inference layer.

A Hierarchical Multi-task Approach for Learning Embeddings from Semantic Tasks

14 Nov 2018huggingface/hmtl

Much effort has been devoted to evaluate whether multi-task learning can be leveraged to learn rich representations that can be used in various Natural Language Processing (NLP) down-stream applications. The model is trained in a hierarchical fashion to introduce an inductive bias by supervising a set of low level tasks at the bottom layers of the model and more complex tasks at the top layers of the model.

Few-shot Learning for Named Entity Recognition in Medical Text

13 Nov 2018mxhofer/Named-Entity-Recognition-BidirectionalLSTM-CNN-CoNLL

Deep neural network models have recently achieved state-of-the-art performance gains in a variety of natural language processing (NLP) tasks (Young, Hazarika, Poria, & Cambria, 2017). However, these gains rely on the availability of large amounts of annotated examples, without which state-of-the-art performance is rarely achievable.

Bayesian Ensembles of Crowds and Deep Learners for Sequence Tagging

2 Nov 2018UKPLab/arxiv2018-bayesian-ensembles

Current methods for sequence tagging, a core task in NLP, are data hungry. Crowdsourcing is a relatively cheap way to obtain labeled data, but the annotators are unreliable, so redundant labeling and aggregation techniques are required.
