Query: Active Multi-Label Crowd Consensus   Crowdsourcing is an economic and efficient strategy aimed at collecting
annotations of data through an online platform. Crowd workers with different
expertise are paid for their service, and the task requester usually has a
limited budget. How to collect reliable annotations for multi-label data and
how to compute the consensus within budget is an interesting and challenging,
but rarely studied, problem. In this paper, we propose a novel approach to
accomplish Active Multi-label Crowd Consensus (AMCC). AMCC accounts for the
commonality and individuality of workers, and assumes that workers can be
organized into different groups. Each group includes a set of workers who share
a similar annotation behavior and label correlations. To achieve an effective
multi-label consensus, AMCC models workers' annotations via a linear
combination of commonality and individuality, and reduces the impact of
unreliable workers by assigning smaller weights to the group. To collect
reliable annotations with reduced cost, AMCC introduces an active crowdsourcing
learning strategy that selects sample-label-worker triplets. In a triplet, the
selected sample and label are the most informative for the consensus model, and
the selected worker can reliably annotate the sample with low cost. Our
experimental results on multi-label datasets demonstrate the advantages of AMCC
over state-of-the-art solutions on computing crowd consensus and on reducing
the budget by choosing cost-effective triplets.
