๐ค AI Summary
Standardized surveys struggle to balance scalability with depth, while traditional qualitative interviews lack procedural consistency. This paper proposes an AI-augmented conversational interviewing framework that integrates real-time interactive probing and automated semantic coding into online questionnaire workflows for the first time. Leveraging an off-the-shelf large language model (LLM) without fine-tuning, the system employs a textbot to dynamically pursue open-ended responses and perform on-the-fly codingโpreserving operational consistency. A randomized controlled trial demonstrates that the method significantly enhances response richness and information density in open-ended items; achieves moderate coding accuracy (with slight false-positive bias); and yields only a modest, yet acceptable, reduction in respondent experience. The study empirically validates the feasibility of AI-enhanced qualitative data collection at scale and establishes a novel paradigm for hybrid survey methodology.
๐ Abstract
Standardized surveys scale efficiently but sacrifice depth, while conversational interviews improve response quality at the cost of scalability and consistency. This study bridges the gap between these methods by introducing a framework for AI-assisted conversational interviewing. To evaluate this framework, we conducted a web survey experiment where 1,800 participants were randomly assigned to text-based conversational AI agents, or"textbots", to dynamically probe respondents for elaboration and interactively code open-ended responses. We assessed textbot performance in terms of coding accuracy, response quality, and respondent experience. Our findings reveal that textbots perform moderately well in live coding even without survey-specific fine-tuning, despite slightly inflated false positive errors due to respondent acquiescence bias. Open-ended responses were more detailed and informative, but this came at a slight cost to respondent experience. Our findings highlight the feasibility of using AI methods to enhance open-ended data collection in web surveys.
