A Neural Layered Model for Nested Named Entity Recognition

NAACL 2018 meizhiju/layered-bilstm-crf

Each flat NER layer is based on the state-of-the-art flat NER model that captures sequential context representation with bidirectional Long Short-Term Memory (LSTM) layer and feeds it to the cascaded CRF layer.

A Feature-Based Model for Nested Named-Entity Recognition at VLSP-2018 NER Evaluation Campaign

22 Mar 2018minhpqn/vietner

In this report, we describe our participant named-entity recognition system at VLSP 2018 evaluation campaign.

Sequence-to-Nuggets: Nested Entity Mention Detection via Anchor-Region Networks

ACL 2019 sanmusunrise/ARNs

In this paper, we propose to resolve this problem by modeling and leveraging the head-driven phrase structures of entity mentions, i. e., although a mention can nest other mentions, they will not share the same head word.

Multi-Grained Named Entity Recognition

ACL 2019 congyingxia/Multi-Grained-NER

This paper presents a novel framework, MGNER, for Multi-Grained Named Entity Recognition where multiple entities or entity mentions in a sentence could be non-overlapping or totally nested.

Neural Segmental Hypergraphs for Overlapping Mention Recognition

EMNLP 2018 berlino/overlapping-ner-em18

In this work, we propose a novel segmental hypergraph representation to model overlapping entity mentions that are prevalent in many practical datasets.

Neural Architectures for Nested NER through Linearization

ACL 2019 ufal/acl2019_nested_ner

We propose two neural network architectures for nested named entity recognition (NER), a setting in which named entities may overlap and also be labeled with more than one label.

Nested Named Entity Recognition via Second-best Sequence Learning and Decoding

5 Sep 2019yahshibu/nested-ner-2019-bert

When an entity name contains other names within it, the identification of all combinations of names can become difficult and expensive.
