摘要:

知识获取是任何知识图谱(KG)应用必不可少的第一步。该知识可以从给定的语料库中提取(KG生成过程)或从现有的KG中指定(KG规范过程)。知识获取侧重于特定领域的解决方案,是一项劳动密集型任务,通常由主题专家协调和监督。具体而言,通常手动定义感兴趣的域,然后利用所需的生成或提取工具来生成KG。本文提出了一种基于Transformers的有监督机器学习方法,用于语料库的领域定义。我们认为,为什么这样的自动定义域的结构是有益的建设时间和质量的生成的图形。该方法通过与基于CNN和RNN模型的两种参考方法进行比较,在三个公共数据集(WebNLG,NYT和DocRED)上进行了广泛的验证。评估表明,我们的模型在这项任务中的效率。专注于科学文档理解,我们提出了一个新的健康领域数据集的基础上,从PubMed中提取的出版物,我们成功地利用我们的方法。最后,我们展示了这项工作如何为全自动和无监督的KG生成奠定基础。

英文摘要:

Knowledge acquisition is the essential first step of any Knowledge Graph (KG) application. This knowledge can be extracted from a given corpus (KG generation process) or specified from an existing KG (KG specification process). Focusing on domain specific solutions, knowledge acquisition is a labor intensive task usually orchestrated and supervised by subject matter experts. Specifically, the domain of interest is usually manually defined and then the needed generation or extraction tools are utilized to produce the KG. Herein, we propose a supervised machine learning method, based on Transformers, for domain definition of a corpus. We argue why such automated definition of the domain's structure is beneficial both in terms of construction time and quality of the generated graph. The proposed method is extensively validated on three public datasets (WebNLG, NYT and DocRED) by comparing it with two reference methods based on CNNs and RNNs models. The evaluation shows the efficiency of our model in this task. Focusing on scientific document understanding, we present a new health domain dataset based on publications extracted from PubMed and we successfully utilize our method on this. Lastly, we demonstrate how this work lays the foundation for fully automated and unsupervised KG generation.
