AbstractKnowledge graphs are typical multi-relational structures, which is consisted of many entities and relations. Nonetheless, existing knowledge graphs are still sparse and far from being complete. To refine the knowledge graphs, representation learning is utilized to embed entities and relations into low-dimensional spaces. Many existing knowledge graphs embedding models focus on learning latent features in close-world assumption but omit the changeable of each knowledge graph.In this paper, we propose a knowledge graph representation learning model, called Caps-OWKG, which leverages the capsule network to capture the both known and unknown triplets features in open-world knowledge graph. It combines the descriptive text and knowledge graph to get descriptive embedding and structural embedding, simultaneously. Then, the both above embeddings are used to calculate the probability of triplet authenticity. We verify the performance of Caps-OWKG on link prediction task with two common datasets FB15k-237-OWE and DBPedia50k. The experimental results are better than other baselines, and achieve the state-of-the-art performance.

DataType-Aware Knowledge Graph Representation Learning in Hyperbolic Space

Knowledge Graph (KG) representation learning aims to encode both entities and relations into a continuous low-dimensional vector space. Most existing methods only concentrate on learning representations from structural triples in Euclidean space, which cannot well exploit the rich semantic information with hierarchical structure in KGs. In this paper, we propose a novel DataType-aware hyperbolic knowledge representation learning model called DT-GCN, which has the advantage of fully embedding attribute values of data types information. We refine data types into five primitive modalities, including integer, double, Boolean, temporal, and textual. For each modality, an encoder is specifically designed to learn its embedding. In addition, we define a unified space based on Euclidean, spherical, and hyperbolic space, which is a continuous curvature space that combines advantages of three different spaces. Extensive experiments on both synthetic and real-world datasets show that our model is consistently better than the state-of-the-art models. The average performance is improved by 2.19% and 3.46% than the optimal baseline model on node classification and link prediction tasks, respectively. The results of ablation experiments demonstrate the advantages of embedding data types information and leveraging the unified space.

Knowledge Graph Representation Learning(KGRL) aims to map entities and relationships into a low-dimensional dense vector space. Most of the existing models focus only on the information of the triple when doing representation learning, ignoring the rich external semantic information. At the same time, these models consider entities and relations as static and single representations, so the knowledge represent ability is poor. Accordingly, we propose a novel knowledge graph representation model which enhanced knowledge graph embedding with multi-information. Firstly, our model carries out text enhancement and hyperbolic space embedding of triples in the knowledge graph respectively; Secondly, we concatenate the enhanced vector. Then, the concatenated vector through two transformation layer to fuse the semantic information and spacial information. Finally, we use the fused information to learn the context information through the Transformer coding layer, which will dynamically produce the final representation of the entity based on its context. Experimental results show that our model has a great improvement over other models. In the link prediction task, the evaluation protocol Hits@10 and MRR in the public dataset FB15k improve by 28.4% and 29.5% compared with the translation model. Compared with state-of-the-art model, the improvement is 2.5%, 6.3%.

Representation Learning of Knowledge Graph is to represent entities and relations in knowledge base as dense low-dimensional vectors. The classic model is the translation model, Bordes et al. [] regard the process in which the head entity relates to the tail entity through relations as the translation process, and then measure the rationality of each triplet with a score function.

We start by introducing hyperbolic representation learning methods for hierarchical graphs, including methods for multi relational graphs or graphs with node features. We demonstrate the benefits of these hyperbolic representations compared to their Euclidean ...
Abstract: Knowledge Graph Question Answering (KGQA) models enable users to acquire entity-based answers from a Knowledge Graph by asking natural language questions (NLQs) without the need to learn a specialized graph query language or knowing the underlying schema of the knowledge graph. This work investigates hyperbolic graph representation learning methods to effectively and efficiently ...

Therefore, nding good knowledge graph representations is a task of fundamental importance. Recent studies have demonstrated that embedding methods are effective and scalable for knowledge graph representation learning. The basic idea is to map the knowledge graph entities and relations to a low dimensional vector space, where the se-

Mirroring work in Euclidean space, we are the first to leverage trainable hyperbolic rotations, a

Quantitative results shows that our method outperforms the best competing method [13] with a significant margin of 3.02%. Fig. 3 shows a visual comparison of our proposed SGR and the best compet-
