Bipartite Flat-Graph Network for Nested Named Entity Recognition

ACL 2020 cslydia/BiFlaG

In this paper, we propose a novel bipartite flat-graph network (BiFlaG) for nested named entity recognition (NER), which contains two subgraph modules: a flat NER module for outermost entities and a graph module for all the entities located in inner layers.

A Unified MRC Framework for Named Entity Recognition

ACL 2020 ShannonAI/mrc-for-flat-nested-ner

Instead of treating the task of NER as a sequence labeling problem, we propose to formulate it as a machine reading comprehension (MRC) task.

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

5 Sep 2019yahshibu/nested-ner-tacl2020-transformers

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

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.

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.

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.

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.

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.
