Comparing Local LLM-Based Extraction of Stakeholder Values for Value Model Visualization in Deliberations
How effectively can local large language models extract information required to generate visualizations of stakeholder value models?
Extracting Value, Value Tension, and Points of Agreement From Deliberation
Can LLMs identify value, value tensions, and consensus points from multi-stakeholder deliberation transcripts?
How to design post-reflection dialogue from transcripts using the identified values, value tensions, and consensus points?
A deliberative approach to modeling retrospection ex post facto in multi-stakeholder decision-making scenarios
A Deliberative AI approach was developed using publicly available transcripts and several open-sources LLMs. The generated reflective dialogue was subsequently evaluated through Synthetic Personae evaluators according to the five metrics established: safety, privacy, autonomy, societal well-being, and points of contention. Two different prompting strategies: single-turn and multi-turn were deployed to see if there were meaningful differences between the two.
The results indicated that the methodology can produce reflective dialogues that are perceived positively, exceeding the predefined success threshold. Furthermore, the iterative multi-turn interactions were found to improve perceived satisfaction compared to the single-turn approach on average.
Although limited to English language deliberations, the findings demonstrate the feasibility of using Deliberative AI to support reflection and, rather than proposing a universal solutions, this work provides a reproducible proof of concept that can be adapted based on future models, transcript contexts, and languages, motivating the development of more LLM-based deliberative systems.

Scaling Deliberative-Quality Measurement with Large Language Models
Validating a Four-Model LLM Ensemble as a Coder for a Theory-Justified Three-Dimension Discourse Quality Index Sub-Codebook on UK House of Commons Debate
two contributions. First, we construct a theory-justified three-dimension DQI sub- codebook — Level of Justification, Respect for Groups, and Counterarguments — defending each inclusion and exclusion from deliberative-democracy theory. Second,
we benchmark a four-model LLM-as-judge ensemble against two trained coders on
200 UK House of Commons public-safety debate acts. We report Gwet’s linear- weighted AC1: trained coders reach AC1 = 0.78, 0.94, and 0.48 on the three dimensions, and the ensemble reaches 0.74, 0.89, and 0.48 against the lead coder.
We also tested whether an LLM can substitute for a human coder, framed as an equivalence test: whether the paired difference in agreement falls within a ±0.10 band of the human–human baseline, judged by where its confidence interval lies rather than by a test against zero. The difference falls within 0.05 of the baseline
on every dimension, and its confidence interval lies inside the band on all three.
The results suggest that on justification and recognition the ensemble can serve as reliable independent measurement, and that on Counterarguments it can serve as a second coder in a doubly-coded design — where the binding constraint appears to
be the codebook anchor language rather than the model. ...

A thematic analysis of people’s experiences
We conducted a reflexive thematic analysis on 650 filtered user responses and examined whether a local version of LLaMA 3.3 (8B) could support the generation of common patterns and themes from qualitative data, and the categorization of such data into predefined themes. Our findings show that participants had mixed experiences. Some felt encouraged and supported by the activities, while others found them confusing, irrelevant to smoking cessation, or difficult to complete due to contextual or environmental barriers.
While the model was able to generate reasonable themes that overlapped with human interpretations, it was unable to reliably label data points using a predefined coding schema, achieving a Cohen’s Kappa of just 0.003. These findings suggest that LLMs may be useful in the early, exploratory stages of qualitative analysis, but currently lack the accuracy needed for theme application in complex, nuanced data. ...

We conducted a deductive thematic analysis of open-ended responses from users who completed a questionnaire after participating in a smoking cessation program with a virtual coach. Additionally, we employed the LLaMA large language model to identify patterns in the responses and to assign the ethical themes discovered during the analysis.
The findings indicate that some users valued fairness and preferred scheduled, randomized interventions or no feedback. Others emphasized autonomy, wanting users to request feedback themselves. Some suggested prioritizing motivated or advanced users. A common view was that interventions should focus on those in need, users at risk of disengagement or health problems, those making little progress, experiencing emotional difficulties, or lacking clarity. The large language model was successful in identifying themes but not in accurately allocating themes, reflected by a low Cohen’s Kappa of 0.05.
The results presenting user preferences can guide the design of interventions that need to be effective and ethically sound. The findings suggest that while large language models can identify themes, they are not yet suitable for allocating those themes. ...

Analyzing users’ introductions to human coaches
Insights from eHealth applications introductions
Objective. Our study aims to identify users’ preferences on ethical principles that a virtual coach should follow to decide when to allocate human feedback to individuals preparing to quit smoking.
Methods. Our research was based on pre-gathered data, that included participants’ responses to open and closed questions regarding feedback allocation principles. Thematic analysis was conducted on these responses. Triangulation was performed using a qualitative literature review and quantitative data analysis.
Results. Four main themes were identified: (1) Struggling the Most (63.75%), (2) Increasing Chances of Success the Most (13.75%), (3) Equal Treatment (11.25%), and (4) Appreciating the Most (11.25%). Participants prioritized support for those experiencing the greatest difficulty in smoking cessation. The triangulation supported the validity of these themes.
Conclusions. Our study highlights the importance of integrating user-preferred ethical principles in virtual coaching systems for smoking cessation. Prioritization of users who struggle the most can increase the effectiveness and fairness of such systems, potentially increasing success rates. Future research should explore additional ethical principles, combining several principles into systems, and real-world application of these findings to further refine virtual coaching in healthcare. ...

Examining the Efficacy of Persuasive eHealth Applications in Facilitating Smoking Cessation
An Analysis of Competency Based Activities
It was determined that engagement with the optional qualitative aspect of the data produced similar utility perspectives on the competencies to those who did not comment. It was noted that the general perspective of the competencies rose after completing the activity, however not to a significant degree. Additionally, no notable correlations between age, gender or educational level and increased perception of the competency arose. Several interesting remarks from participants were analysed to offer considerations for any future research in this field. ...
