Joint Entity and Relation Extraction with Span Pruning and Hypergraph Neural Networks

1 code implementation26 Oct 2023 Zhaohui Yan, Songlin Yang, Wei Liu, Kewei Tu

Also, most of current ERE models do not take into account higher-order interactions between multiple entities and relations, while higher-order modeling could be beneficial. In this work, we propose HyperGraph neural network for ERE ($\hgnn{}$), which is built upon the PL-marker (a state-of-the-art marker-based pipleline model).

Modeling Instance Interactions for Joint Information Extraction with Neural High-Order Conditional Random Field

1 code implementation17 Dec 2022 Zixia Jia, Zhaohui Yan, Wenjuan Han, Zilong Zheng, Kewei Tu

Prior works on joint Information Extraction (IE) typically model instance (e. g., event triggers, entities, roles, relations) interactions by representation enhancement, type dependencies scoring, or global decoding.

Controllable Length Control Neural Encoder-Decoder via Reinforcement Learning

no code implementations17 Sep 2019 Junyi Bian, Baojun Lin, Ke Zhang, Zhaohui Yan, Hong Tang, Yonghe Zhang

Here, we denote a concept of Controllable Length Control (CLC) for the trade-off between length control capacity and semantic accuracy of the language generation model.
