Can personas extracted from documents generalize across evaluation tasks?
This explores whether automating persona creation from domain documents—rather than hand-crafting roles—enables multi-agent evaluators to transfer across different tasks without redesign. The question matters because manual personas fail to generalize across domains.
Multi-agent evaluation frameworks like ChatEval assign agents to pre-defined roles ("general public," "critic") and manually craft evaluation dimensions. This works for one task but fails to generalize: a "critic" in summarization may not carry the same evaluative priorities to dialogue generation. MAJ-EVAL (2025) addresses this by automating the entire persona creation pipeline from domain documents.
The process has two steps. First, evaluative dimension extraction: given domain-specific documents (e.g., research papers), the system identifies stakeholders (parents, clinicians, educators) and their associated perspectives, priorities, and evaluation criteria — with evidence chains linking dimensions to specific claims in the source documents. Semantically similar stakeholders are clustered and redundant dimensions merged, preserving diversity within groups.
Second, dimension-based persona construction: for each consolidated dimension, a detailed persona is constructed with five attributes — demographic information, evaluative dimension, domain specialty, psychological traits, and social relationships. These personas ground the evaluation agents in real stakeholder perspectives rather than arbitrary role assignments.
The evaluation itself runs in three phases: (1) individual agent assessment from unique perspectives, (2) multi-agent in-group free debate moderated by a coordinating agent that prioritizes unresolved disagreements, and (3) aggregation across groups combining qualitative synthesis with quantitative score averaging. This mirrors how real stakeholder groups deliberate — initial positions → debate → consensus.
The key advantage is reproducibility and transferability. Because personas are extracted from documents rather than hand-crafted, the same pipeline applies to children's storybook QA and medical literature summarization without redesign. Since How do we generate realistic personas at population scale?, the document-grounded approach provides the calibration anchor that ad hoc persona generation lacks.

How do we generate realistic personas at population scale?
Current LLM-based persona generation relies on ad hoc methods that fail to capture real-world population distributions. The challenge is reconstructing the joint correlations between demographic, psychographic, and behavioral attributes from fragmented data.

When multiple AI agents debate, they often converge without actually deliberating. Can a dedicated agent reliably identify true agreement versus false consensus, and would that improve debate outcomes?
