Machine-Learning for Spammer Detection in Crowd-Sourcing
Halpin, Harry (W3C/Massachusetts Institute of Technology) | Blanco, Roi (Yahoo! Research)
Over a series of evaluation experiments conducted using naive judges recruited and managed via Amazon's Mechanical Turk facility using a task from information retrieval (IR), we show that a SVM shows itself to have a very high accuracy when the machine-learner is trained and tested on a single task and that the method was portable from more complex tasks to simpler tasks, but not vice versa.
