MedMentions:一个用UMLS概念注释的大型生物医学语料库

MedMentions: A Large Biomedical Corpus Annotated with UMLS Concepts

Chan Zuckerberg Initiative(陈·扎克伯格倡议)

摘要:

本文介绍了正式发布的MedMentions,一个新的手动注释的资源,用于识别生物医学概念。MedMentions与其他注释生物医学语料库的区别在于它的大小(超过4,000个摘要和超过350,000个链接提及),以及概念本体的大小(来自UMLS 2017的300多万个概念)及其对生物医学学科的广泛覆盖。除了完整的语料库之外,还提供了MedMentions的子语料库,包括针对文档检索的UMLS 2017子集的注释。为了鼓励生物医学命名实体识别和链接方面的研究,该版本中包含了用于训练和测试的数据分割,还描述了用于实体链接的基线模型及其度量。

英文摘要:

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.
