Learning temporal granularity with quadruplet networks for temporal knowledge graph completion [PDF]

open access: yesScientific Reports
Temporal Knowledge Graphs (TKGs) capture the dynamic nature of real-world facts by incorporating temporal dimensions that reflect their evolving states. These variations add complexity to the task of knowledge graph completion.

A Brief Survey on Deep Learning-Based Temporal Knowledge Graph Completion

open access: yesApplied Sciences
Temporal knowledge graph completion (TKGC) is the task of inferring missing facts based on existing ones in a temporal knowledge graph. In recent years, various TKGC methods have emerged, among which deep learning-based methods have achieved state-of-the-

Temporal Knowledge Graph Completion Using Box Embeddings

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2022
Knowledge graph completion is the task of inferring missing facts based on existing data in a knowledge graph. Temporal knowledge graph completion (TKGC) is an extension of this task to temporal knowledge graphs, where each fact is additionally associated with a time stamp.

Tucker decomposition-based temporal knowledge graph completion [PDF]

open access: yesKnowledge-Based Systems, 2022
Knowledge graphs have been demonstrated to be an effective tool for numerous intelligent applications. However, a large amount of valuable knowledge still exists implicitly in the knowledge graphs. To enrich the existing knowledge graphs, recent years witness that many algorithms for link prediction and knowledge graphs embedding have been designed to ...

Context-aware Temporal Knowledge Graph Completion Based on Relation Constraints [PDF]

open access: yesJisuanji kexue, 2023
The existing temporal knowledge graph completion models only consider the structural information of the quadruple itself,ignoring the implicit neighbor information and the constraints of relationships on entities,which leads to the poor perfor-mance of ...

Temporal Knowledge Graph Completion: A Survey

open access: yesProceedings of the Thirty-Second International Joint Conference on Artificial Intelligence, 2023
Knowledge graph completion (KGC) predicts missing links and is crucial for real-life knowledge graphs, which widely suffer from incompleteness. KGC methods assume a knowledge graph is static, but that may lead to inaccurate prediction results because many facts in the knowledge graphs change over time.

Knowledge Graph Embeddings: Open Challenges and Opportunities [PDF]

open access: yesTransactions on Graph Data and Knowledge, 2023
While Knowledge Graphs (KGs) have long been used as valuable sources of structured knowledge, in recent years, KG embeddings have become a popular way of deriving numeric vector representations from them, for instance, to support knowledge graph ...

TeMP: Temporal Message Passing for Temporal Knowledge Graph Completion [PDF]

open access: yesProceedings of the 2020 Conference on Empirical Methods in Natural Language Processing (EMNLP), 2020
Inferring missing facts in temporal knowledge graphs (TKGs) is a fundamental and challenging task. Previous works have approached this problem by augmenting methods for static knowledge graphs to leverage time-dependent representations. However, these methods do not explicitly leverage multi-hop structural information and temporal facts from recent ...

A Simple But Powerful Graph Encoder for Temporal Knowledge Graph Completion

open access: yesCoRR, 2021
Knowledge graphs contain rich knowledge about various entities and the relational information among them, while temporal knowledge graphs (TKGs) describe and model the interactions of the entities over time. In this context, automatic temporal knowledge graph completion (TKGC) has gained great interest.
