Contextualized Word Representations from Distant Supervision with and for NER

WS 2019  ·  Abbas Ghaddar, Phillippe Langlais ·

We describe a special type of deep contextualized word representation that is learned from distant supervision annotations and dedicated to named entity recognition. Our extensive experiments on 7 datasets show systematic gains across all domains over strong baselines, and demonstrate that our representation is complementary to previously proposed embeddings. We report new state-of-the-art results on CONLL and ONTONOTES datasets.
