Data validation

I have question regarding annotating. If there are 2 annotators and I want share them same data to verify results. Is it possible to do on a single instance.

Not within the same instance or session, because there’s no way to identify the user and the browser session and pass that information forward to the server and keep track of separate annotation queues.

If you want two people to annotate the same data, you probably want to do this in two sessions (e.g. on different ports) with the same recipes and input data but two separate target datasets which you can then compare later on.

(Btw, if you are looking for more advanced user management features, see the thread on the upcoming Prodigy Scale, which will also include tools for measuring annotator performance and data quality etc.)
