Hi all: Pretty new user here. I have been trying to use qualifications in order to keep people from taking the survey multiple times. After some struggling I thought I had done so. I created a qualification, I assigned a value of "1" to everyone who had completed the HIT, and then tried a new batch with the qualification that they had to have a value "not equal to 1" in order to participate.

The problem: Several hours have passed, and no one has done the HIT. Before the qualification, people did so within minutes. Have I somehow established a qualification that prevents EVERYONE from doing the HIT?

I would be grateful for any advice anyone might suggest.

 

Thanks so much for this response--I don't know much about the worker side! Have you tried requesting qualification? And if so, what happened? I'm not aware of receiving any such requests, but maybe they are coming in and I don't know where to find them. If you have not requested qualification, would you mind doing so in order for me to see what happens. Again, many thanks.

 

I think you want to use "Already completed this HIT - does not exist" instead of "is not 1." I don't know the exact logic behind it, but for example my qualification level is None, maybe "is not 1" is looking for some other number to compare to.

 

This is a pretty dated post https://blog.mturk.com/new-qualific...er-flexibility-to-qualifications-12cea07cdd2b, but it might give you an idea of how the DoesNotExist qualification works. It does seem as though you have disqualified everyone. It appears to me as though you are essentially granting a qual of 1 to everyone who took your survey, but then disqualified all of them, like telling someone they can have access to the coffee machine, but then sealing it in a safe, so they can't, but no one else can access it either. So, you are really close, it just didn't get executed correctly.

In its current form, the only people that can accept the HIT are people who have been assigned that qualification with any score other than 1.
Fixing the HIT to say "Already completed this HIT does not exist" should have it function the way you intended.

 

Thanks so much for this. After looking high and low for your request, I came across this on a message board:

"Many new users spend time requesting qualifications thinking that a requester will see the request and hopefully grant it. However requesters are never notified of requests. The only way for a requester to see if workers have requested their qualifications is to use the command-line tools or mTurk API, neither of which are user friendly. This makes the practice of requesting qualifications largely fruitless."

I've gotta say, MTurk is not making any of this easy . . .

Again, I can't thank you enough for your help.

 

SUCCESS!

Thanks to everyone who responded. The trick was using the "does not exist" comparator. And speaking of "does not exist", that is an excellent description of my chances of figuring this out without your help.
