Evaluating 5W3H Structured Prompting for Intent Alignment in Human-AI Interaction

This paper tests whether a structured prompting framework called PPS (based on 5W and 3H questions) helps AI systems better understand what users actually want. The researchers compared three ways of giving instructions to AI models across different tasks and found that naturally-written structured prompts work better than simple prompts or raw technical formats, especially for ambiguous business tasks, and users needed fewer follow-up questions overall.
