Lease Option Clause Retrieval Benchmark Dataset
This benchmark focuses on five easily confused rights in lease agreements: renewal options, purchase options, expansion rights, rights of first tenancy, and rights of first refusal to purchase. Samples include retrieval queries, contract context, target clauses, and highly similar distractor clauses, alongside annotations for right-related semantic features, candidate comparisons, distractor strength, and retrieval difficulty. The data supports evaluation and improvement of legal RAG systems on fine-grained contractual right retrieval and discrimination.
