Towards Temporal Knowledge Graph Alignment in the Wild

CoRR
Temporal Knowledge Graph Alignment (TKGA) seeks to identify equivalent entities across heterogeneous temporal knowledge graphs (TKGs) for fusion to improve their completeness. Although some approaches have been proposed to tackle this task, most assume unified temporal element standards and simplified temporal structures across different TKGs.

Pioneering Temporal Knowledge Graph Completion with Large Language Models: A Text Generation Approach

The Journal of Engineering
Traditional temporal knowledge graph completion (TKGC) methods often rely on random encoding or pre‐trained small‐scale language models to initialize entity and relation embeddings. Despite the remarkable reasoning and understanding capabilities of large

A Survey on Spatio-Temporal Knowledge Graph Models

CoRR
Many complex real-world systems exhibit inherently intertwined temporal and spatial characteristics. Spatio-temporal knowledge graphs (STKGs) have therefore emerged as a powerful representation paradigm, as they integrate entities, relationships, time and space within a unified graph structure.
