This paper presents the formal release of MedMentions, a new manually annotated resource for the recognition of biomedical concepts. What distinguishes MedMentions from other annotated biomedical corpora is its size (over 4,000 abstracts and over 350,000 linked mentions), as well as the size of the concept ontology (over 3 million concepts from UMLS 2017) and its broad coverage of biomedical disciplines. In addition to the full corpus, a sub-corpus of MedMentions is also presented, comprising annotations for a subset of UMLS 2017 targeted towards document retrieval. To encourage research in Biomedical Named Entity Recognition and Linking, data splits for training and testing are included in the release, and a baseline model and its metrics for entity linking are also described.

介绍了 MedMentions 作为一种新的手动注释的生物医学概念识别资源，并描述了其 UMLS 2017 概念本体论中超过 3 百万个具体概念和 4000+ 个文摘和 350,000 多个链接提到的规模以及广泛覆盖生物医学学科领域的优点。同时，也提出了 MedMentions 子集，支持针对文档检索的实体识别任务。该数据集已包含训练、测试集，并且还提供了 Named Entity Recognition 的基线模型以及其指标，以鼓励相关领域的研究。
