Research Notes & Methodology Updates
Methodology versioning notes. Aggregate, anonymized category benchmarks. Reading on the history of independent measurement. We don't publish marketing posts, vendor comparisons we have a stake in, or thought leadership about how AI is changing everything. The point of these notes is to make Valoh's measurement work auditable in public.
Most Recent
We've moved prompt-set review from quarterly to biannual, expanded the sentiment rubric to better capture cautionary framing, and published a new validation κ for recommendation strength. This note documents what changed, why, and how prior windows compare.
