为了解决软件众包任务定价决策阶段可用信息有限的问题,提出一种基于层次注意力模型的软件众包定价方法。利用层次注意力模型提取软件众包任务需求文本语义特征,可以在需求文本中自动发掘与任务价格相关的有效信息。此外,将文本划分成词和句两个层次对全文进行有重点的表示,可以更好地表示文本特征。实验结果表明,该方法能够有效克服生产环境的局限性,降低特征提取难度,并在一定程度上提高了预测性能。 相似文献

Task assignment, the core problem of Spatial Crowdsourcing (SC), is often modeled as an optimization problem with multiple constraints, and the quality and efficiency of its solution determines how well the SC system works. Fairness is a critical aspect of task assignment that affects worker participation and satisfaction. Although the existing studies on SC have noticed the fairness problem, they mainly focus on fairness at the individual level rather than at the group level. However, differences among groups in certain attributes (e.g. race, gender, age) can easily lead to discrimination in task assignment, which triggers ethical issues and even deteriorates the quality of the SC system. Therefore, we study the problem of task assignment with group fairness for SC. According to the principle of fair budget allocation, we define a well-designed constraint that can be considered in the task assignment problem of SC systems, resulting in assignment with group fairness. We mainly consider the task assignment problem in a common One-to-One SC system (O2-SC), and our goal is to maximize the quality of the task assignment while satisfying group fairness and other constraints such as budget and spatial constraints. Specifically, we first give the formal definition of task assignment with group fairness constraint for O2-SC. Then, we prove that it is essentially an NP-hard combinatorial optimization problem. Next, we provide a novel fast algorithm with theoretical guarantees to solve it. Finally, we conduct extensive experiments using both synthetic and real datasets. The experimental results show that the proposed constraint can significantly improve the group fairness level of algorithms, even for a completely random algorithm. The results also show that our algorithm can efficiently and effectively complete the task assignment of SC systems while ensuring group fairness. 相似文献

This article proposes a new framework to model a scenario in which First Responders, citizens, smart devices, or robots explore the environment in an emergency situation, i.e., after an earthquake, assessing damages and searching for people needing assistance. While moving, the agents observe events and exchange the information collected with other agents encountered: to this end, they use messaging systems purposely adapted to use point-to-point network connections to allow local data exchange between agents even when global network connections are not available. As is common in Delay Tolerant Networks, exchanged messages are locally stored: when a global network is available, the agents can upload all the information collected by themselves and other agents they encountered to a Control Room or a database in the Cloud. Differently from traditional DTN algorithms such as Epidemic and Spray&Wait, we propose a solution that keeps track of agents that shared information along the path and assess the quality of the information collected by multiple agents through a reputation-based mechanism that is safer than majority voting. A simulator compatible with OpenStreetMap is presented, as well as simulated experiments in two Italian towns to validate the feasibility of the approach. 相似文献

以威客模式众包为研究对象,采用实证方法研究影响发布方创新绩效的主要因素。分析并构建发布方创新绩效影响因素的理论模型,提出了研究假设,利用从任务中国网站抓取的1 400条悬赏任务数据,验证模型假设。实证分析表明发布方在合理提升任务奖金的同时,在任务时长和任务描述长度的设计上需要平衡所期望获得的解决方案的数量和质量;而发布方的经验对解答方案的数量和质量均无正向影响,发布方需要通过提升自身的信用提升绩效。 相似文献
