New Study on Dynamics of MTurk

Here is a brand spanking new study to be presented in May in Florence about the MTurk marketplace. Panos Ipeirotis left the link in the comments on a post a few weeks ago (Thanks PANOS!) and there’s some great information here.

Some of their findings reflect my own very unscientific analysis of HITS:

Tasks related to audio transcription have been gaining momentum in the last years and are today the most popular tasks on Amazon MTurk. The popularity of Content Access HITs has decreased over time. Surveys are however becoming more popular over time especially in the US. Surveys are the most popular type of HITs for US- based workers.

And here are two other tidbits that if you are like me, you will enjoy:

The most frequent HIT reward value has increased over time, and reaches $0.05 in 2014.AND New requesters constantly join Amazon MTurk, making the total number of active requesters and the avail able reward increase over time.

Excellent study, congratulations to Panos and his co-authors! Here is the citation:
