Wormingo: a 'true gamification' approach to anaphoric annotation

In this paper we present Wormingo, 1 a new Game-with-a-Purpose for anaphoric annotation. It introduces the motivation-annotation paradigm which uses linguistic puzzles and other widely known gamification techniques and word game mechanics to motivate players to carry out anaphoric annotation tasks. In a preliminary experiment, the game was tested on 270 players recruited through the Reddit platform, achieving promising results.
