Updating Embeddings for Dynamic Knowledge Graphs

open access: yesCoRR, 2021
Data in Knowledge Graphs often represents part of the current state of the real world. Thus, to stay up-to-date the graph data needs to be updated frequently. To utilize information from Knowledge Graphs, many state-of-the-art machine learning approaches use embedding techniques.

Enabling inductive knowledge graph completion via structure-aware attention network [PDF]

open access: yes, 2023
: Knowledge graph completion (KGC) aims at complementing missing entities and relations in a knowledge graph (KG). Popular KGC approaches based on KG embedding are typically limited to the transductive setting, i.e., all entities must be seen during ...

SUKE: Embedding Model for Prediction in Uncertain Knowledge Graph

open access: yesIEEE Access, 2021
Graph embedding models are widely used in knowledge graph completion (KGC) task. However, most models are based on the assumption that knowledge is completely certain, and this is inconsistent with real-world situations.

A Novel Time Constraint-Based Approach for Knowledge Graph Conflict Resolution

open access: yesApplied Sciences, 2019
Knowledge graph conflict resolution is a method to solve the knowledge conflict problem in constructing knowledge graphs. The existing methods ignore the time attributes of facts and the dynamic changes of the relationships between entities in knowledge ...

Convolutional Complex Knowledge Graph Embeddings [PDF]

open access: yes, 2021
In this paper, we study the problem of learning continuous vector representations of knowledge graphs for predicting missing links. We present a new approach called ConEx, which infers missing links by leveraging the composition of a 2D convolution with a Hermitian inner product of complex-valued embedding vectors.

Embedding Uncertain Knowledge Graphs

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2019
Embedding models for deterministic Knowledge Graphs (KG) have been extensively studied, with the purpose of capturing latent semantic relations between entities and incorporating the structured knowledge they contain into machine learning. However, there are many KGs that model uncertain knowledge, which typically model the inherent uncertainty of ...

Locally Adaptive Translation for Knowledge Graph Embedding [PDF]

open access: yes, 2016
Knowledge graph embedding aims to represent entities and relations in a large-scale knowledge graph as elements in a continuous vector space. Existing methods, e.g., TransE and TransH, learn embedding representation by defining a global margin-based loss
