There has been considerable efforts in modelling
the semantics of Internet of Things and their specific context.
Acquiring and managing metadata related to the physical devices
and their surrounding environment becomes challenging due
to the dynamic nature of environment. This paper focuses on
managing metadata for Internet of Things with the help of
crowds. Specifically, the paper proposes a collaborative approach
for collecting and maintaining metadata through micro tasks that
can be performed using variety of platforms e.g. mobiles, laptops, kiosks, etc. The approach allows non-experts to contribute
towards metadata management through micro tasks, therefore
resulting in reduced cost and time. Applicability of the proposed
approach is demonstrated through a use case implementation
for managing sensor metadata for energy management in small
buildings
