Abstract

CAPTCHA is a type of widely applied security measures to prevent abuses of online services. Our research is focused on designing a new type of CAPTCHA called AnnoCAPTCHA, which can harness the intellectual power of Web users to perform corpus annotation - an expensive step for computational linguistic analysis. We analyzed the applicability and the efficiency of AnnoCAPTCHA. We also conducted user study to demonstrate its accessibility.
