I used MTurk for a data gathering project recently. Turnaround time is great: within a few hours. You can set params to only accept people whose rejection rate is 5% or less or what not (95% acceptance rate is the default) to weed out the riffraff. Pretty cost effective. My instructions were complex (check websites A, B, and C and on each, look for data elements X, Y and Z and do the hokey-pokey and...) and as a result the quality wasn't great. To avoid: I'd recommend either farming out each subtask into a separate HIT or aggregating the entire task in a single HIT. --SET Aaron Rubinstein wrote: > I'm looking at Amazon's Mechanical Turk, https://www.mturk.com/mturk/welcome > to "automate" checking the page order of 11,000 scanned books (some were > scanned backwards by a long out-of-business vendor). > > Does anyone on the list have experience using Mechanical Turk?
