Objective: Disease knowledge graphs are a way to connect, organize, and access disparate information about diseases with numerous benefits for artificial intelligence (AI). To create knowledge graphs, it is necessary to extract knowledge from multimodal datasets in the form of relationships between disease concepts and normalize both concepts and relationship types.
Methods: We introduce REMAP, a multimodal approach for disease relation extraction and classification. The REMAP machine learning approach jointly embeds a partial, incomplete knowledge graph and a medical language dataset into a compact latent vector space, followed by aligning the multimodal embeddings for optimal disease relation extraction.
Results: We apply REMAP approach to a disease knowledge graph with 96,913 relations and a text dataset of 1.24 million sentences. On a dataset annotated by human experts, REMAP improves text-based disease relation extraction by 10.0% (accuracy) and 17.2% (F1-score) by fusing disease knowledge graphs with text information. Further, REMAP leverages text information to recommend new relationships in the knowledge graph, outperforming graph-based methods by 8.4% (accuracy) and 10.4% (F1-score).
Conclusion: REMAP is a multimodal approach for extracting and classifying disease relationships by fusing structured knowledge and text information. REMAP provides a flexible neural architecture to easily find, access, and validate AI-driven relationships between disease concepts.

背景资料:从非结构化文本中自动提取化学-疾病关系对于疾病治疗和药物开发具有重要意义。与此同时,生物医学专家已经建立了许多高度结构化的知识库(KBs),其中包含有关化学品和疾病的先验知识。先验知识为CDR提取提供了强有力的支持。如何充分利用它是值得研究的问题。结果:本文提出了一种新的模型,称为“知识引导卷积网络(KCN)”,利用先验知识的CDR提取。该模型首先从知识库中学习包括实体嵌入和关系嵌入的知识表示。然后,使用实体嵌入来控制上下文特征向具有门控卷积的化学疾病对的传播。在此基础上,通过共享注意池,利用关系嵌入进一步获取加权上下文特征。最后,包含额外知识信息的加权上下文特征用于CDR提取。在BioCreative V CDR数据集上的实验表明,所提出的KCN达到了71.28%的F1分数,这优于大多数最先进的系统。结论:本文提出了一种新的CDR提取模型KCN,以充分利用先验知识。实验结果表明,KCN可以有效地集成先验知识和上下文的性能提高。

自动提取化学物质与疾病之间的关系对于生物医学研究和医疗保健的各个领域都非常重要。生物医学专家已经建立了许多大规模的知识库(KB),以推动生物医学研究的发展。知识库中包含了大量的实体和关系的结构化信息,因此在化学疾病关系(CDR)提取中起着至关重要的作用。然而,以往的研究较少关注知识库中存在的先验知识。本文提出了一种基于神经网络的注意力模型(NAM)用于CDR提取,该模型充分利用了文档中的上下文信息和知识库中的先验知识。对于文档中的一对实体,采用注意力机制来选择关于从知识库中学习的关系表示的重要上下文词。在BioCreative V CDR数据集上的实验表明,通过注意力机制将上下文和知识表示相结合,可以显着提高CDR提取性能,同时实现与最先进系统相当的结果。

化学-疾病关系(CDR)提取对于生物医学研究和医疗保健的各个领域都非常重要。目前,许多大型生物医学知识库(KBs)已经建立,其中包含关于实体对及其关系的三元组。知识库是生物医学关系抽取的重要资源。然而,以往的研究很少关注先验知识。此外,依赖树包含了重要的句法和语义信息,有助于改进关系抽取。因此如何有效地利用它也是值得研究的。在本文中,我们提出了一种新的卷积注意力网络(CAN)的CDR提取。首先,我们提取一个句子中的化学和疾病对之间的最短依赖路径(SDP),它包括一个单词序列,依赖方向,和依赖关系标签。然后对SDP执行卷积运算以产生深度语义依赖特征。之后,采用注意力机制来学习与从知识库学习的知识表示相关的每个语义依赖向量的重要性/权重。最后,为了结合依赖信息和先验知识,加权语义依赖表示和知识表示的级联被馈送到softmax层进行分类。在BioCreative V CDR数据集上的实验表明,该方法的性能与最先进的系统相当,依赖信息和先验知识在CDR提取任务中起着重要作用。
