OGER++: hybrid multi-type entity recognition

open access: yesJournal of Cheminformatics, 2019
Background We present a text-mining tool for recognizing biomedical entities in scientific literature. OGER++ is a hybrid system for named entity recognition and concept recognition (linking), which combines a dictionary-based annotator with a corpus ...

Improving Multilingual Named Entity Recognition with Wikipedia Entity Type Mapping [PDF]

open access: yesProceedings of the 2016 Conference on Empirical Methods in Natural Language Processing, 2016
The state-of-the-art named entity recognition (NER) systems are statistical machine learning models that have strong generalization capability (i.e., can recognize unseen entities that do not appear in training data) based on lexical and contextual ...

Named entity recognition [PDF]

open access: yesProceedings of the 19th international conference on Computational linguistics -, 2002
This paper presents a maximum entropy-based named entity recognizer (NER). It differs from previous machine learning-based NERs in that it uses information from the whole document to classify each word, with just one classifier. Previous work that involves the gathering of information from the whole document often uses a secondary classifier, which ...

Local Feature Enhancement for Nested Entity Recognition Using a Convolutional Block Attention Module

open access: yesApplied Sciences, 2023
Named entity recognition involves two main types: nested named entity recognition and flat named entity recognition. The span-based approach treats nested entities and flat entities uniformly by classifying entities on a span representation. However, the

Cross-Lingual Named Entity Recognition Based on Attention and Adversarial Training

open access: yesApplied Sciences, 2023
Named entity recognition aims to extract entities with specific meaning from unstructured text. Currently, deep learning methods have been widely used for this task and have achieved remarkable results, but it is often difficult to achieve better results

Indirectly Named Entity Recognition

open access: yesJournal of Computer-Assisted Linguistic Research, 2021
We define here indirectly named entities, as a term to denote multiword expressions referring to known named entities by means of periphrasis.  While named entity recognition is a classical task in natural language processing, little attention has been paid to indirectly named entities and their treatment.

Spanish named entity recognition in the biomedical domain [PDF]

open access: yes, 2018
Named Entity Recognition in the clinical domain and in languages different from English has the difficulty of the absence of complete dictionaries, the informality of texts, the polysemy of terms, the lack of accordance in the boundaries of an entity ...
