TKG-Thinker: Towards Dynamic Reasoning over Temporal Knowledge Graphs via Agentic Reinforcement Learning
TKG-Thinker introduces a novel agent for Temporal Knowledge Graph Question Answering (TKGQA) that employs autonomous planning and adaptive retrieval via Agentic Reinforcement Learning. It addresses limitations of current LLM-based methods, such as reasoning hallucinations and static workflows, by using a dual-training strategy: Supervised Fine-Tuning for planning, followed by Reinforcement Learning with multi-dimensional rewards. Experiments demonstrate state-of-the-art performance and strong generalization across complex TKGQA settings.

Dynamic Bounded Verification (Before Last Question)
TKG-Thinker dynamically performs bounded verification via repeated search_between calls, updating candidates from 'Association of Southeast Asian Nations' to 'Qatar' and finally to 'Japan', showcasing its ability to avoid temporal reasoning hallucinations and ensure accuracy.
Cross-domain Generalization (TimelineKGQA)
Although not trained on TimelineKGQA, TKG-Thinker successfully adapts its tool usage strategy, verifies temporal consistency, and produces correct answers, demonstrating strong generalization to previously unseen temporal settings and complex temporal characteristics.
