Researchers from the NOWJ team have detailed their multi-stage pipeline approach for the COLIEE 2026 competition, which focuses on legal retrieval and reasoning tasks. Their methodology involves a combination of filtering, dense retrieval with various embedding models, and reranking techniques for legal case retrieval. For entailment tasks, they employed LLM-based verification and retrieval-augmented generation frameworks. The team also introduced dynamic routing for query difficulty classification and utilized hierarchical transformers with CRF layers for legal judgment prediction. AI
