Named Entity Recognition (NER) is an essential precursor task for many natural language applications, such as relation extraction or event extraction. Much of the NER research has been done on datasets with few classes of entity types (e.g. PER, LOC, ORG, MISC), but many real world applications (disaster relief, complex event extraction, law enforcement) can benefit from a larger NER typeset. More recently, datasets were created that have hundreds to thousands of types of entities, sparking new…

Fine-grained Named Entity Recognition using only Coarse-grained labels
TLDR
Fine-grained NER is necessary to get a better understanding of the entities and should further help with the information extraction, given only the entities’ coarse- grained labels.

An Empirical Study on Fine-Grained Named Entity Recognition
TLDR
An empirical comparison of FG-NER models for English and Japanese is presented and it is demonstrated that LSTM+CNN+CRF (Ma and Hovy, 2016), one of the state-of-the-art methods for English NER, also works well for EnglishFG-NER but does not work well for Japanese, a language that has a large number of character types.
Fine-Grained Entity Recognition
TLDR
A fine-grained set of 112 tags is defined, the tagging problem is formulates as multi-class, multi-label classification, an unsupervised method for collecting training data is described, and the FIGER implementation is presented.
Context-Dependent Fine-Grained Entity Type Tagging
TLDR
This work proposes the task of context-dependent fine type tagging, where the set of acceptable labels for a mention is restricted to only those deducible from the local context (e.g. sentence or document).
Overview of TAC-KBP 2019 Fine-grained Entity Extraction
TLDR
An outline of the Ultra-Fine-Grained Name Tagging for Entity Types task at the Knowledge Base Population (KBP) track at TAC 2019 is given and remaining challenges and future research directions are sketched out.
Towards Lingua Franca Named Entity Recognition with BERT
TLDR
This paper investigates a single Named Entity Recognition model, based on a multilingual BERT, that is trained jointly on many languages simultaneously, and is able to decode these languages with better accuracy than models trained only on one language.
End-to-end Sequence Labeling via Bi-directional LSTM-CNNs-CRF
TLDR
A novel neutral network architecture is introduced that benefits from both word- and character-level representations automatically, by using combination of bidirectional LSTM, CNN and CRF, thus making it applicable to a wide range of sequence labeling tasks.
A framework for named entity recognition in the open domain
In this paper, a system for Named Entity Recognition in the Open domain (NERO) is described. It is concerned with recognition of various types of entity, types that will be appropriate for…
Towards large-scale, open-domain and ontology-based named entity classification
TLDR
The main contribution of the paper is a systematic analysis of the impact of varying certain parameters on such a context-based approach exploiting similarities in vector space for the disambiguation of named entities.
A survey of named entity recognition and classification
TLDR
Observations about languages, named entity types, domains and textual genres studied in the literature, along with other critical aspects of NERC such as features and evaluation methods, are reported.
Yago: a core of semantic knowledge
TLDR
YAGO builds on entities and relations and currently contains more than 1 million entities and 5 million facts, which includes the Is-A hierarchy as well as non-taxonomic relations between entities (such as HASONEPRIZE).
