The Effects of Choice in Routing Relevance Judgments

The emergence of human computation systems, including

Mechanical Turk and games with a purpose, has made it feasible

to distribute relevance judgment tasks to workers over the Web.

Most human computation systems assign tasks to individuals

randomly, and such assignments may match workers with tasks

that they may be unqualified or unmotivated to perform. We

compare two groups of workers, those given a choice of queries to

judge versus those who are not, in terms of their self-rated

competence and their actual performance. Results show that

when given a choice of task, workers choose ones for which they

have greater expertise, interests, confidence, and understanding.
