摘要:

我们介绍BioCoM,一个对比学习框架的生物医学实体链接,只使用两个资源:一个小型的字典和大量的原始生物医学文章。具体来说,我们建立了训练实例从原始PubMed文章的字典匹配,并使用它们训练上下文感知的实体连接模型与对比学习。我们通过最近邻搜索在推理时预测归一化的生物医学实体。结果发现,BioCoM大大优于国家的最先进的模型,特别是在低资源的设置,通过有效地利用实体的上下文。

英文摘要:

We introduce BioCoM, a contrastive learning framework for biomedical entity linking that uses only two resources: a small-sized dictionary and a large number of raw biomedical articles. Specifically, we build the training instances from raw PubMed articles by dictionary matching and use them to train a context-aware entity linking model with contrastive learning. We predict the normalized biomedical entity at inference time through a nearest-neighbor search. Results found that BioCoM substantially outperforms state-of-the-art models, especially in low-resource settings, by effectively using the context of the entities.
