Abstract
In order to validate a particular approach to trust modeling, researchers have typically designed simulations in which various multliagent conditions are modeled and tested. Graphs have tracked different measures to demonstrate success of the proposed trust model, including satisfaction of buying agents, profit of selling agents (in e-marketplaces) or the extent to which the simulation matched some ground truth for the user. In this paper we report on an effort to locate and employ existing datasets with information about real users, in order to validate a trust model. We describe how Reddit and Epinions datasets can be put to good use, towards this end. In addition to describing what we did for the validation of our own trust model, we reflect on how other trust modeling researchers may perform a similar process, of benefit for their own empirical studies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
