“…Violations to the schema are automatically detected and directed to manual checks. This approach is in line with the recent trend in complementing automatic processing with human intervention, which is leading to very promising research in social computing (e.g., FoldIt 1 ), human computation (e.g., ESP games [31]) and crowdsourcing (e.g., Amazon Mechanical Turk 2 ). We evaluated the approach on the YAGO ontology [3] which was selected because it does not have a fixed schema, and because its 2009 version has been never evaluated before.…”

“…In [42], for example, participants arrived sequentially, and only saw information about the behavior of previous participants, while in [43], at most pairs of participants were required to be present simultaneously. In our experiment, however we required all players to participate simultaneously-a problem that is solved in physical labs by announcing official start times and supervising experiments with trained proctors.…”

Cooperation and contagion in web-based, networked public goods experiments

A longstanding idea in the literature on human cooperation is that cooperation should be reinforced when conditional cooperators are more likely to interact. In the context of social networks, this idea implies that cooperation should fare better in highly clustered networks such as cliques than in networks with low clustering such as random networks. To test this hypothesis, we conducted a series of web-based experiments, in which 24 individuals played a local public goods game arranged on one of five network topologies that varied between disconnected cliques and a random regular graph. In contrast with previous theoretical work, we found that network topology had no significant effect on average contributions. This result implies either that individuals are not conditional cooperators, or else that cooperation does not benefit from positive reinforcement between connected neighbors. We then tested both of these possibilities in two subsequent series of experiments in which artificial seed players were introduced, making either full or zero contributions. First, we found that although players did generally behave like conditional cooperators, they were as likely to decrease their contributions in response to low contributing neighbors as they were to increase their contributions in response to high contributing neighbors. Second, we found that positive effects of cooperation were contagious only to direct neighbors in the network. In total we report on 113 human subjects experiments, highlighting the speed, flexibility, and cost-effectiveness of webbased experiments over those conducted in physical labs.

“…The incentives to make people contribute can be of different kinds: they can give the participant an explicit and concrete reward (like in the popular Amazon Mechanical Turk 10 in which people are paid to perform small and simple tasks) or they provide a different kind of implicit or more abstract return, for example by means of entertainment like in Games with a Purpose [28] (GWAP).…”

“…To check our hypothesis, we built UrbanMatch [7], a location-based Game with a Purpose [28] in the form of a mobile application 9 . Specifically, UrbanMatch is aimed at exploiting players' experience of the urban environment to correctly link points of interests in the city with their most representative photos retrieved from Web sources.…”

Abstract.To realize the Smart Cities vision, applications can leverage the large availability of open datasets related to urban environments. Those datasets need to be integrated, but it is often hard to automatically achieve a high-quality interlinkage. Human Computation approaches can be employed to solve such a task where machines are ineffective. We argue that in this case not only people's background knowledge is useful to solve the task, but also people's physical presence and direct experience can be successfully exploited. In this paper we present UrbanMatch, a Game with a Purpose for players in mobility aimed at validating links between points of interest and their photos; we discuss the design choices and we show the high throughput and accuracy achieved in the interlinking task.
