摘要

•Word embeddings trained from clinical notes, literature, Wikipedia, and news are compared.•Word embeddings trained from clinical notes and literature capture word semantics better.•There isn’t a consistent global ranking of word embeddings for biomedical NLP applications.•Word embeddings trained from biomedical domain corpora do not necessarily perform better.
