Published: 21 February 2026 at WSDM '26, The Nineteenth ACM International Conference on Web Search and Data Mining.
Executive Impact Summary
Dynamic Knowledge Graphs (KGs) are constantly evolving, presenting significant challenges for traditional AI models. This research introduces DyGM, a novel framework designed to intelligently manage non-stationary KG growth. DyGM addresses issues like inefficient knowledge transfer, catastrophic forgetting, and imbalanced learning priorities by integrating connectivity-aware structuring, cross-snapshot memory relay, and dynamic weight balancing. Our experiments demonstrate DyGM's superior adaptability and performance, especially in dynamic, real-world KG environments, providing a robust solution for enterprises building resilient and continuously learning AI systems.

Link Prediction in Action: DyGM vs. Baselines
This case study illustrates DyGM's superior ability to predict links in non-stationary Knowledge Graphs, specifically from the NS-FB-1 dataset.
Early Snapshot (S1) - Nationality Prediction
Query: Walter Elias "Walt" Disney, /people/person/nationality, ?
- DyGM Result: The United States of America, Canada, Denmark
- IncDE Result: India, Germany, The United States of America
- LKGE Result: The United Kingdom of Great Britain and Northern Ireland, Sweden, Germany
Analysis: DyGM correctly ranks "The United States of America" as the first result, while IncDE places it third, and LKGE fails to include it in the top three. This highlights DyGM's robust long-term memory and its global distillation mechanism, effectively preserving historical entity features and resisting forgetting despite non-stationary updates.
Recent Snapshot (S12) - Profession Prediction
Query: Joan Chong Chen, /people/person/profession, ?
- DyGM Result: Actor, Television producer, Voice acting
- IncDE Result: Actor, Voice acting, Television producer
- LKGE Result: Television producer, Comedian, Actor
Analysis: All three models correctly identify "Actor" within their top three predictions. DyGM's prediction sequence, along with IncDE, aligns more closely with literally semantic relationships, demonstrating its adaptive learning of new entity associations and its capacity to generate robust embedding representations.
