The original title is "NOWJ@COLIEE 2026: Adaptive Pipelines for Legal Retrieval and Reasoning"

Short summary

The NOWJ team presents adaptive pipelines for all five tasks of the COLIEE 2026 legal AI competition, covering legal case retrieval, entailment, statute law retrieval, and legal judgment prediction. Approaches include dense retrieval with cross-encoder reranking, T5-based reranking with LLM entailment verification, RAG frameworks with few-shot reasoning, and dynamic routing based on query difficulty. Each task employs tailored multi-stage architectures combining retrieval, reranking, and reasoning components.

• •Covers all five COLIEE 2026 tasks: case retrieval, case entailment, statute retrieval, textual entailment, and judgment prediction
• •Uses diverse approaches including dense retrieval, cross-encoder reranking, RAG with few-shot prompting, and dynamic difficulty-based routing
• •Combines hierarchical transformers with CRF layers and argumentation graph reasoning for legal judgment prediction
