ChemNER: Fine-Grained Chemistry Named Entity Recognition with Ontology-Guided Distant Supervision

EMNLP 2021main

Scientific literature analysis needs fine-grained named entity recognition (NER) to provide a wide range of information for scientific discovery. For example, chemistry research needs to study dozens to hundreds of distinct, fine-grained entity types, making consistent and accurate annotation diffic…
