HVAC Maintenance Procedure Answer Verification Dataset
Designed for evaluating maintenance question answering for industrial HVAC equipment, this dataset records maintenance questions, candidate action steps, and structured procedure references covering step order, prerequisites, and safety restrictions. It also provides step-by-step mappings, missing requirements, safety violations, completeness scores, and overall assessments. These records support automated evaluation of answer completeness, procedural compliance, and safety, as well as system improvement and benchmarking.
