PersonaCite: VoC-Grounded Interviewable Agentic Synthetic AI Personas for Verifiable User and Design Research

LLM-based and agent-based synthetic personas are increasingly used in design and product decision-making, yet prior work shows that prompt-based personas often produce persuasive but unverifiable responses that obscure their evidentiary basis. We present PersonaCite, an agentic system that reframes AI personas as evidence-bounded research instruments through retrieval-augmented interaction. Unlike prior approaches that rely on prompt-based roleplaying, PersonaCite retrieves actual voice-of-customer artifacts during each conversation turn, constrains responses to retrieved evidence, explicitly abstains when evidence is missing, and provides response-level source attribution. Through semi-structured interviews and deployment study with 14 industry experts, we identify preliminary findings on perceived benefits, validity concerns, and design tensions, and propose Persona Provenance Cards as a documentation pattern for responsible AI persona use in human-centered design workflows.

AI-based Classification of Customer Support Tickets: State of the Art and Implementation with AutoML

Automation of support ticket classification is crucial to improve customer support performance and shortening resolution time for customer inquiries. This research aims to test the applicability of automated machine learning (AutoML) as a technology to train a machine learning model (ML model) that can classify support tickets. The model evaluation conducted in this research shows that AutoML can be used to train ML models with good classification performance. Moreover, this paper fills a research gap by providing new insights into developing AI solutions without a dedicated professional by utilizing AutoML, which makes this technology more accessible for companies without specialized AI departments and staff.

Human-Centered AI Product Prototyping with No-Code AutoML: Conceptual Framework, Potentials and Limitations

This paper evaluates No-Code AutoML as a solution for challenges in AI product prototyping, characterized by unpredictability and inaccessibility to non-experts, and proposes a conceptual framework. This complexity of AI products hinders seamless execution and interdisciplinary collaboration crucial for human-centered AI products. Relevant to industry and innovation, it affects strategic decision-making and investment risk mitigation. Current approaches provide limited insights into the potential and feasibility of AI product ideas. Employing Design Science Research, the study identifies challenges and integrates no-code AutoML as a solution by presenting a framework for AI product prototyping with No-code AutoML. A case study confirms its potential in supporting non-experts, offering a structured approach to AI product development. The framework facilitates accessible and interpretable prototyping, benefiting academia, managers, and decision-makers. Strategic integration of no-code AutoML enhances efficiency, empowers non-experts, and informs early-stage decisions, albeit with acknowledged limitations.
