Pretraining large neural language models, such as BERT, has led to impressive gains on many natural language processing (NLP) tasks. However, most pretraining efforts focus on general domain corpora, such as newswire and Web. A prevailing assumption is that even domain-specific pretraining can benefit by starting from general-domain language models.
Recent work shows that for domains with abundant unlabeled text, such as biomedicine, pretraining language models from scratch results in substantial gains over continual pretraining of general-domain language models.
This BiomedBERT is pretrained from scratch using
abstracts from
PubMed. This model achieves state-of-the-art performance on several biomedical NLP tasks, as shown on the
Biomedical Language Understanding and Reasoning Benchmark.
