  • 分视图建模历史证据与演化动态,分别构建对应图结构
  • 在多个基准上达到当前最优性能,显著提升预测准确率
  • 适合时序知识图谱、事件预测等需要长期与短期信息融合的任务

时序知识图谱(TKG)推理旨在从历史事实中预测未来事件。其关键挑战在于同时捕捉两类预测信息:历史证据与演化动态。然而现有方法多仅关注其中一类,限制了对互补预测信号的充分挖掘。为此,我们提出CHE-TKG,一种新型协同双视图学习框架,用于TKG推理。该方法显式分离并联合建模历史证据与演化动态,以学习并利用其互补的预测信号。具体地,构建历史证据图以捕获长期结构规律与稳定关系约束,同时构建演化动态图以建模时间转移与近期变化,并为每类视图设计专用编码器。进一步引入关系分解与对比对齐目标,增强两视图间的预测信号捕捉能力。大量实验表明,CHE-TKG在多个基准上实现领先性能。

原文摘要 · Abstract (English)

Temporal knowledge graph (TKG) reasoning aims to predict future events from historical facts. A key challenge lies in jointly capturing two sources of predictive information in TKGs: historical evidence and evolutionary dynamics. However, existing methods typically focus on only one of these sources, which limits the ability to fully exploit the complementary predictive signals in TKGs. To address this, we propose CHE-TKG, a novel collaborative dual-view learning framework for TKG reasoning. CHE-TKG explicitly separates and jointly models historical evidence and evolutionary dynamics, aiming to learn and exploit their complementary predictive signals. Specifically, CHE-TKG constructs a historical evidence graph to capture long-term structural regularities and stable relational constraints, alongside an evolutionary dynamics graph to model temporal transitions and recent changes, with dedicated encoders for each view. We further employ relation decomposition and a contrastive alignment objective to better capture the predictive signals across the two views. Extensive experiments demonstrate that CHE-TKG achieves state-of-the-art performance on multiple benchmarks.
