Knowledge base refinement with gamified crowdsourcing

Abstract

This paper discusses a gamification design for knowledge base refinement. The maintenance of a knowledge base involves human intervention and is one major application domain of human computation. Using the concept of crowdsourcing, refinement tasks can be delegated to many casual users over a network. In addition, gamification such as games with a purpose (GWAP) is a useful idea to motivate workers in crowdsourcing by making a task into a playful game. For effective gamification, designing the game rules is critical. In this paper, we present a model for simulating the gamified knowledge base refinement process to estimate the effects of different game rule designs beforehand.
