KG-BERT是一种基于BERT的模型,用于知识图谱的补全。该模型将知识图谱中的三元组视为文本序列,并利用BERT的语言模型能力对三元组进行建模。具体来说,KG-BERT将实体和关系表示为它们的名称或描述,然后将三元组的名称/描述词序列作为BERT模型的输入句子进行微调。通过这种方式,KG-BERT能够利用上下文信息和大规模语料信息来...
KG-BERT: BERT for Knowledge Graph Completion The repository is modified frompytorch-pretrained-BERTand tested on Python 3.5+. Installing requirement packages pip install -r requirements.txt Data (1) The benchmark knowledge graph datasets are in ./data. ...
BackBone选择BERT,提出KG-BERT模型在预训练好的BERT基础上继续fine-tuning。 Triple Classification 将三元组转换为文本序列模式,转换方法如下图所示: 将实体、关系的名称或描述文本,通过[CLS]和[SEP]进行顺序拼接,喂入KG-BERT中后,获得[CLS]的表征向量,并进行二分类,判断该三元组是否成立。
KG-BERT也能够根据其上下文理解其语义,并预测出与之相关的实体或关系。
在处理自然语言处理(NLP)问题,尤其是知识图谱(KG)与预训练语言模型(如BERT)融合应用时,分词与链接预测任务的挑战引人深思。分词器将输入文本分解为更小单位以提高模型处理未知词汇的能力。BERT使用WordPiece算法,将复杂词汇分解为词根、前缀、后缀等。这虽然扩展了模型词汇范围,但对具有特定语义的...
我们将知识图中的三元组视为文本序列,并提出了一个新的框架,名为知识图双向编码器表示(KG-BERT)来对这些三元组进行建模。我们的方法以三元组的实体和关系描述作为输入,并使用KG-BERT语言模型计算三元组得分函数。 2、相关工作 最近,预先训练的语言模型也在KG的背景下进行了探索。(Wang、Kulkarni和Wang 2018)学习...
Our method takes entity and relation descriptions of a triple as input and computes scoring function of the triple with the KG-BERT language model. Experimental results on multiple benchmark knowledge graphs show that our method can achieve state-of-the-art performance in triple classification, ...

BERTScore is an effective and robust automatic metric for referencebased machine translation evaluation. In this paper, we incorporate multilingual knowledge graph into BERTScore and propose a metric named KG-BERTScore, which linearly combines the results of BERTScore and bilingual named entity matching...
