Train a Domain-Specific Reranker for a Legal-Tech Search Box
Overview
What this challenge is about.
Fine-tune a cross-encoder on 20k legal triples, evaluate it, then deliver the model and deployment plan. Get a verifiable certificate.
The Brief
What you'll do, and what you'll demonstrate.
Lift contract-search nDCG@10 with a domain-fine-tuned reranker without blowing the latency budget.
Earning criteria — what you'll demonstrate
- Fine-tune a cross-encoder reranker on domain pairs
- Evaluate retrieval+rerank stacks with nDCG and Recall
- Measure inference latency under a deployment-realistic load
- Design a fallback path for ML model failures
