Abstract
Every Web user is a potential knowledge contributor, but it is a challenge to make them
devote their time contributing to some purpose. In order to align individual with social
interests, I will present an extension of the CAPTCHA Web resource protection
application to embed knowledge elicitation within the users' main task of accessing a
Web resource. Consequently, unlike previous knowledge acquisition approaches, no extra
effort is expected from users since they are already willing to use a CAPTCHA to
perform some particular task.
We present two applications of this mechanism: one that collects image labels from Web
users, where experimental results suggest the feasibility of this approach, and another that
collects textual transcriptions to auditory media.
