. . . . "At a more technical level, many Linked Data management tasks have already been subject to human computation, be that in the form of games with a purpose [27,38] or, closer to our work, paid microtasks. Games with a purpose, which capitalize on entertain- ment, intellectual challenge, competition, and reputation, offer another mechanism to engage with a broad user base. In the field of semantic technologies, the OntoGame series proposes several games that deal with the task of data interlinking, be that in its ontology alignment instance (SpotTheLink [38]) or multimedia interlinking (SeaFish [37]). Similar ideas are imple- mented in GuessWhat?!, a selection-agreement game which uses URIs from DBpedia, Freebase and OpenCyc as input to the interlinking process [27]. While OntoGame looks into game mechanics and game narratives and their applicability to finding similar enti- ties and other types of correspondences, our research studies an alternative crowdsourcing strategy that is based on financial rewards in a microtask platform. Most relevant for our work are the experiments comparing games with a purpose and paid microtasks, which showed the complementarity of the two forms of crowdsourcing [32,9]." . . . .
