relation extraction update

[ajaynagesh]

Some notes:

A Joint Neural Model for Information Extraction with Global Features (ACL 2020) -- not considered

• https://www.aclweb.org/anthology/2020.acl-main.713.pdf (clearly relation extraction performance in Chinese is poorer than that of the present table in ChineseNLP)

Chinese Relation Extraction with Multi-Grained Information and External Linguistic Knowledge (ACL 2019) -- considered, also adds a new dataset (Chinese SanWen dataset)

• https://www.aclweb.org/anthology/P19-1430.pdf
• https://github.com/thunlp/Chinese_NRE source code
• 3 datasets
  • ACE 2005 -- beats Chen+2014 (from ChineseNLP table, 2nd row)
  • Chinese SanWen: papers that report on this dataset -- This paper --- 65.61 -- Chinese Relation Extraction Using Lattice GRU (IEEE) https://ieeexplore.ieee.org/abstract/document/9085019 -- behind paywall -- 57.43 -- Chinese relation extraction based on lattice network improved with BERT model (ACM) https://dl.acm.org/doi/abs/10.1145/3395260.3395276 - behind paywall -- 63.13 -- A Discourse-Level Named Entity Recognition and Relation Extraction Dataset for Chinese Literature Text (arxiv) -- 55.6 -- introduced this dataset
  • FinRE (this paper) -- no other paper uses this dataset
