ExpertCoT
The reasoning module of the LEGO framework. It hard-codes the legal syllogism into a reasoning template, requiring the model to follow a structured provision–fact–conclusion chain, ensuring that the reasoning process is principled and traceable.
Timeline (last 90 days)
LEGO is a dual-module framework composed of two components, ExpertGraphRAG and ExpertCoT, designed to address the two bottlenecks of retrieval and reasoning in legal reasoning.
ExpertCoT organizes the retrieved provisions and case facts into a structured reasoning chain of provision–fact–conclusion, simulating the legal syllogism.
Ablation experiments confirm that the ExpertGraphRAG and ExpertCoT modules each make independent contributions and that the two are complementary.
