Anonymize Mechanical Turk Worker IDs

Posted by Jonathan Robinson on Jan 18, 2016 6:32:00 PM

We recently launched a ground-breaking feature that helps protect Mechanical Turk worker identities. It has been reported in the literature that Mechanical Turk Worker IDs can be used to identify the worker. This is because Amazon uses the same value for both the Worker ID on Mechanical Turk and elsewhere on Amazon properties like Amazon.com product reviews.

Block Duplicate IP Addresses

Our most popular feature request has been to allow the blocking of multiple workers from the same IP address.

HyperBatch - Run Batched HITs at Hyper Speeds

Posted by Jonathan Robinson on Jan 5, 2016 2:24:00 PM

HyperBatch Feature

You can now run your Amazon Mechanical Turk studies at Hyper speeds. We worked hard to make the experience identical to our classic MicroBatch option so that you simply launch your study and TurkPrime does all the heavy lifting for you.

WorkerId (and all MTurk Fields) Sent to Qualtrics

Posted by Jonathan Robinson on Oct 18, 2015 1:47:00 AM

TurkPrime can now automatically add Worker ID, HIT ID, and Assignment ID to data files, including CSV and SPSS files. These variables can be very useful when you want to match Workers across multiple data files. For example, in longitudinal studies, researchers typically ask Workers to provide their Worker IDs in order to pair responses collected at different points in time.

Our Micro-batching Feature will Improve the Quality of Your Data

MicroBatch

We have deployed a micro-batching feature which allows Requesters to break up their studies into smaller segments, and to include time intervals between the segments. We developed this feature to increase sample representation. This feature can also save 50% in MTurk fees.

Exclude Workers With One Click

Posted by Jonathan Robinson on May 7, 2015 3:57:00 PM

Problem:

Suppose you're running a Mechanical Turk survey and need to exclude workers who took a previous survey. How can you quickly set this up.

Some of the currently used solutions require following multiple steps to set things up and are not turnkey solutions and others require Workers to enter their Worker ID, which may self-filter workers and limit the number of workers taking your survey.

Finding More Mechanical Turk Workers Faster with TurkPrime "Restart HIT"

Posted by Jonathan Robinson on Mar 24, 2015 2:47:00 PM

Problem:

Suppose you need to run a HIT with 1000 Workers. Or a HIT that is only open to Workers who have an approval Rating of 95% or more and have completed 500 HITs or more. Although when you launched your HIT the MTurk Workers arrived at a nice pace, over time, the pace has slowed to a trickle such that your HIT will never complete.

Creating Mechanical Turk Custom Panels with TurkPrime Worker Groups

Posted by Jonathan Robinson on Mar 23, 2015 1:29:00 PM

Problem:

Suppose you need to run a group of HITs open only to participants who are women under 50. You previously ran a HIT and know the Worker IDs that you want to reach, but have no way to email them and limit your survey to only them. How can you proceed?
