RAG for MBSE Engineering Requirements: Knowledge Base and Evaluation Data

This dataset accompanies the paper "Traceable MBSE Requirements: Evidence Attribution, Evaluation Bias, and Knowledge-Base Maturity." It contains the curated domain knowledge base (1,307 evidence units annotated with a 21-component × 45-aspect engineering taxonomy), the expert review sample (20 stratified requirements with blind pairwise judgments from two independent domain engineers), and evaluation outputs (H_hard contradiction rates, blind pairwise quality evaluation results, and RAG v3 generation outputs) for the ship main engine cooling water system. All data are required to reproduce the reported evaluation results.
