Query: Task Assignment on Spatial Crowdsourcing [Experiments and Analyses]
  (Technical Report)   Recently, with the rapid development of mobile devices and the crowdsourcing
platforms, the spatial crowdsourcing has attracted much attention from the
database community. Specifically, spatial crowdsourcing refers to sending a
location-based request to workers according to their positions, and workers
need to physically move to specified locations to conduct tasks. Many works
have studied task assignment problems in spatial crowdsourcing, however, their
problem settings are different from each other. Thus, it is hard to compare the
performances of existing algorithms on task assignment in spatial
crowdsourcing. In this paper, we present a comprehensive experimental
comparison of most existing algorithms on task assignment in spatial
crowdsourcing. Specifically, we first give general definitions about spatial
workers and spatial tasks based on definitions in the existing works such that
the existing algorithms can be applied on the same synthetic and real data
sets. Then, we provide an uniform implementation for all the tested algorithms
of task assignment problems in spatial crowdsourcing (open sourced). Finally,
based on the results on both synthetic and real data sets, we discuss the
strengths and weaknesses of tested algorithms, which can guide future research
on the same area and practical implementations of spatial crowdsourcing
systems.
