摘要:

协作式移动众包(CMCS)允许平台招募工人团队来协作执行复杂的感知任务。这种协作的效率可能会受到工人之间信任关系的影响。为了获取社交网络中所有工人之间的非对称信任值,本文提出了基于图卷积神经网络(GCNs)的信任强化评估框架(TREF)。本文通过综合考虑工人的能力收益、距离收益和信任收益来全面计算任务完成效果。工人招募问题被建模为无向完全招募图(UCRG),并为此提出了一种特定的禁忌搜索招募(TSR)算法解决方案。TSR算法为每个任务招募最优执行团队,并在隐私损失的约束下获得任务的协作团队。为了在大规模和广范围上提升招募算法的效率,引入了Mini-Batch K-Means聚类算法和边缘计算技术,从而实现分布式工人招募。最后,在五个真实数据集上进行的大量实验验证了本文提出的招募算法优于其他基线方法。此外,本文提出的TREF超越了文献中现有最先进信任评估方法的性能。

英文摘要:

Collaborative Mobile Crowdsourcing (CMCS) allows platforms to recruit worker teams to collaboratively execute complex sensing tasks. The efficiency of such collaborations could be influenced by trust relationships among workers. To obtain the asymmetric trust values among all workers in the social network, the Trust Reinforcement Evaluation Framework (TREF) based on Graph Convolutional Neural Networks (GCNs) is proposed in this paper. The task completion effect is comprehensively calculated by considering the workers' ability benefits, distance benefits, and trust benefits in this paper. The worker recruitment problem is modeled as an Undirected Complete Recruitment Graph (UCRG), for which a specific Tabu Search Recruitment (TSR) algorithm solution is proposed. An optimal execution team is recruited for each task by the TSR algorithm, and the collaboration team for the task is obtained under the constraint of privacy loss. To enhance the efficiency of the recruitment algorithm on a large scale and scope, the Mini-Batch K-Means clustering algorithm and edge computing technology are introduced, enabling distributed worker recruitment. Lastly, extensive experiments conducted on five real datasets validate that the recruitment algorithm proposed in this paper outperforms other baselines. Additionally, TREF proposed herein surpasses the performance of state-of-the-art trust evaluation methods in the literature.
