KDW at SemEval-2026 Task 12: Logic-Driven Distillation with Knowledge Graphs for Efficient Abductive Reasoning
Summary
The KDW system, presented at SemEval-2026 Task 12, tackles the substantial computational cost associated with large language models (LLMs) such as GPT-4 and Gemini when performing abductive reasoning. This innovative system integrates knowledge graph (KG) evidence extraction with knowledge distillation, a technique designed to transfer structured reasoning abilities from a large teacher model to a more compact student model. Developed for the "Abductive Event Reasoning: Towards Real-World Event Causal Inference for Large Language Models" shared task, KDW secured an 8th place ranking. Notably, it achieved performance levels comparable to frontier LLMs, but at a mere fraction of their typical inference cost, offering a compelling solution for efficient, high-performance reasoning.
Key takeaway
For Machine Learning Engineers facing high computational costs with LLMs for abductive reasoning, you should consider implementing knowledge distillation techniques. The KDW system demonstrates that integrating knowledge graph evidence with distillation allows compact student models to achieve performance comparable to frontier LLMs. This significantly reduces inference costs compared to models like GPT-4 and Gemini. Adopt this approach to deploy powerful reasoning capabilities more efficiently, making advanced AI more accessible for real-world event causal inference tasks.
