Diachronic Embedding for Temporal Knowledge Graph Completion

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2020
Knowledge graphs (KGs) typically contain temporal facts indicating relationships among entities at different times. Due to their incompleteness, several approaches have been proposed to infer new facts for a KG based on the existing ones–a problem known as KG completion.

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:methods and progress

open access: yes大数据, 2021
Temporal knowledge graph (TKG) are obtained by adding the time information of real-world knowledge to classical knowledge graphs.Recently, TKG completion has drawn much attention and become a hot topic in research.Two main methodologies for TKG ...

Unsupervised Entity Alignment for Temporal Knowledge Graphs

open access: yesCoRR, 2023
Entity alignment (EA) is a fundamental data integration task that identifies equivalent entities between different knowledge graphs (KGs). Temporal Knowledge graphs (TKGs) extend traditional knowledge graphs by introducing timestamps, which have received increasing attention.

Extrapolation over temporal knowledge graph via hyperbolic embedding

open access: yesCAAI Transactions on Intelligence Technology, 2023
Predicting potential facts in the future, Temporal Knowledge Graph (TKG) extrapolation remains challenging because of the deep dependence between the temporal association and semantic patterns of facts.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
