Reference Methodology

How “best” is used on this site

How the word is used, the criteria behind it, and the part of a supplier claim that only a pilot can settle.

Answer in brief

On this site, “best” means the data that fits a stated agent task and passes the buyer’s own acceptance test. It describes editorial focus and buying criteria, not a measured league table, a certification, or a claim that one supplier outperforms another.

Two buyers with different tasks should reach different conclusions from the same entries. The criteria below are what the topic guides are written against; they say what to ask for, not what any supplier scored.

This site is a procurement reference, not an independent ranking or certification body. Where an introduction leads to a paid engagement it may receive a referral fee from the supplier; the about page carries the full disclosure.

What the word means here

“Best” appears in the domain and the page titles because buyers search for it. Inside the entries it means the best fit for a defined task, under stated constraints, judged against evidence the buyer can check. There is no overall supplier of the year, no composite score, and no claim that a fit for one task is superior in another.

That also sets the limit of what the site knows. An entry can describe what a supplier publishes; it cannot report how that supplier performed on your data. The about page states the site’s role and disclosures in full.

The criteria

Five questions do most of the work when suppliers are compared.

  1. Task clarity. Can the supplier restate the task boundary, intended behavior and definition of success in its own words?
  2. Reviewability. Who did the work, who reviewed it, against which written rubric, and how disagreements were resolved.
  3. Provenance. Where each example came from, on what permission basis, what changed, and which review history travels with the file. See provenance.
  4. Integration needs. Schema, delivery format, whether the work includes a verifier or environment, and who maintains it after delivery.
  5. Acceptance evidence. The sample you can run, the pilot you can bound, and the method you will use to decide. Evidence that arrives after payment is not acceptance evidence.

Price is deliberately not on that list: it belongs in the comparison once all five questions have comparable answers; before that, it quotes a different scope. The sequence is in how to buy AI agent training data.

What a buyer can verify, and what this site cannot

A buyer can verify four things before committing budget: a sample on their own task, the schema and file format, the reviewer record for that sample, and the acceptance method written down in advance. A bounded pilot adds a fifth: how the supplier handles corrections once work is underway.

Everything else is second-hand. The site can repeat a supplier’s stated scope and point to documentation; it cannot see inside an engagement, inspect logs that were never shared, or confirm that a corpus improves a model. The source register marks the boundary.

Keep resource types distinct

Software, service and dataset are different purchases and should not be compared as one line item.

  • Software. Tooling the buyer operates. Cost is licensing, setup and staff time; the supplier’s role ends at the tool.
  • Service. A team that produces artifacts to a brief, usually with rubric design, reviewer calibration and a correction process. The deliverable is the reviewed work.
  • Dataset or marketplace. A catalog item licensed as delivered. Fit depends on how closely its collection conditions match the buyer’s task.

A supplier whose scope is data only is not comparable to one that also writes the rubric and builds the verifier. The entity map shows where those responsibilities sit.

What the examples are

Checklists and worked comparisons on this site are proposed workflows, not experiments run by this directory, and no result in them was measured here.

A link to a paper or to official documentation records where a claim comes from and who is making it; it does not endorse a supplier. The glossary keeps the vocabulary consistent.

Questions & answers

Does this methodology produce a ranking?
No. It describes five criteria in the order they are applied. No supplier receives a score, a star rating or a position in a list.
Can the guidance replace a pilot?
No. Only a sample on your own task, reviewed by your team, shows how a supplier handles your data. The guidance makes that bounded pilot cheaper to design and easier to judge.
