Toward gamification of knowledge base construction

Knowledge is integral to an intelligent system. However, constructing a knowledge base often involves great cost and substantial effort on the part of human experts in the target domain. In this paper, we present an approach that harnesses the power of casual users to construct the knowledge base. The users answer a simple series of questions and, by aggregating their answers, we obtain the information necessary to augment and refine the knowledge base. To motivate the users to engage in the process, we presented the questions via a gamification approach. Our experiments with the knowledge base of an Apartment FAQ system substantiate the potential of our proposed approach.
