What You Can Verify

Data You Can Have Verified

If a person can check it against a source, an image or a place, it can be verified on RapidWorkers.

AI dataset labels

Is the label, category or transcript correct for this item? Used for cleaning training and test data.

Product catalogs

Do the title, price, image and category match the product page? For e-commerce and marketplaces.

Business listings

Does the business exist, is it open, are the name and address right? For maps, directories and lead lists.

Web data

Do links work, does the page contain the stated information? For scraped and aggregated data.

Images and media

Does the image match its description, is it clear and usable? For media libraries and AI datasets.

Locations

Is there really a shop or sign at this place today? A local worker uploads a photo as proof.

Methods

Ways Workers Can Verify Your Data

Pick the check that matches your data: online sources, visuals, local visits or double review.

Online source check

Workers open a link or search a public source and compare it with your record.

Visual check

Workers look at an image, video or document and confirm it matches the label or description.

Local field check

Workers in a city visit a public place, such as a shop or a street, and upload a photo as proof.

Double verification

Two or more workers check the same batch independently. You keep the answers they agree on.

Privacy

Businesses, Products and Places Only

Verification tasks cover public business information, products, places and your own datasets — not private individuals.

Businesses and products

Verification covers public business information, products, places and your own datasets.

Public places only

Field checks are for shops, streets and other public locations — never private homes or people.

No private individuals

Tasks that ask workers to look up, visit or contact private individuals are not allowed.

Accuracy

Get Results You Can Trust

You decide what counts as verified and review every submission before it joins your clean file.

Person writing verification definitions at a laptop

Clear definitions

Give a clear definition of verified, wrong and unclear so every worker judges the same way.
