In the field of representation learning on knowledge graphs (KGs), a
hyper-relational fact consists of a main triple and several auxiliary
attribute-value descriptions, which is considered more comprehensive and
specific than a triple-based fact. However, currently available
hyper-relational KG embedding methods in a single view are limited in
application because they weaken the hierarchical structure that represents the
affiliation between entities. To overcome this limitation, we propose a
dual-view hyper-relational KG structure (DH-KG) that contains a
hyper-relational instance view for entities and a hyper-relational ontology
view for concepts that are abstracted hierarchically from the entities. This
paper defines link prediction and entity typing tasks on DH-KG for the first
time and constructs two DH-KG datasets, JW44K-6K, extracted from Wikidata, and
HTDM based on medical data. Furthermore, we propose DHGE, a DH-KG embedding
model based on GRAN encoders, HGNNs, and joint learning. DHGE outperforms
baseline models on DH-KG, according to experimental results. Finally, we
provide an example of how this technology can be used to treat hypertension.
Our model and new datasets are publicly available.

提出了使用双视图超关系知识图谱的表示学习模型，其中包括以实体为中心的超关系示例视图和以概念为中心的超关系本体视图。将该模型应用于链接预测和实体类型预测任务，并基于 Wikidata 和医疗数据构建了两种双视图超关系数据集。通过采用 DHGE 模型，该模型的实验结果优于基线模型，并且最后提供的样例表明该技术可以用于治疗高血压。
