Label Refinement via Contrastive Learning for Distantly-Supervised Named Entity Recognition

1 code implementation Findings (NAACL) 2022 Huaiyuan Ying, Shengxuan Luo, Tiantian Dang, Sheng Yu

Distantly-supervised named entity recognition (NER) locates and classifies entities using only knowledge bases and unlabeled corpus to mitigate the reliance on human-annotated labels.

Sentence Alignment with Parallel Documents Facilitates Biomedical Machine Translation

1 code implementation17 Apr 2021 Shengxuan Luo, Huaiyuan Ying, Jiao Li, Sheng Yu

Materials and Methods: Document-level translations are mixed to train bilingual word embeddings (BWEs) for the evaluation of cross-lingual word similarity, and sentence distance is defined by combining semantic and positional similarities of the sentences.
