Query: Building Robust Crowdsourcing Systems with Reputation-aware Decision
  Support Techniques   Crowdsourcing refers to the arrangement in which contributions are solicited
from a large group of unrelated people. Due to this nature, crowdsourcers (or
task requesters) often face uncertainty about the workers' capabilities which,
in turn, affects the quality and timeliness of the results obtained. Trust is a
mechanism used by people to facilitate interactions in human societies where
risk and uncertain are common. The crucial challenge to building a robust
crowdsourcing system is how to make trust-aware task delegation decisions to
efficiently utilize the capacities of workers (or trustee agents) to achieve
high social welfare?
  This book presents the research addressing this challenge. It goes beyond the
existing trust management research framework by removing a widespread
assumption implicitly adopted by existing research: that a trustee agent can
process an unlimited number of interaction requests per discrete time unit
without compromising its performance as perceived by the task requesters (or
truster agents). Decision support in crowdsourcing is re-formalized as a
multi-agent trust game based on the principles of the Congestion Game, which is
solved by two trust-aware interaction decision-making approaches: 1) the Social
Welfare Optimizing approach for Reputation-aware Decision-making (SWORD)
approach, and 2) the Distributed Request Acceptance approach for Fair
utilization of Trustee agents (DRAFT). SWORD is designed for centralized
systems, while DRAFT is designed for fully distributed systems. Theoretical
analyses have shown that the social welfare produced by these two approaches
can be made closer to optimal by adjusting only one key parameter. With these
two approaches, the framework of research for crowdsourcing systems can be
enriched to handle more realistic scenarios where workers have varied and
limited capabilities.
