论文摘要
基于接近性的接触跟踪取决于移动设备的相互作用来估计疾病的传播。 Sharetrace就是一种方法，可以通过考虑直接和间接的接触形式来提高跟踪疾病扩散的功效。在这项工作中，我们利用Actor模型通过在时间触点网络上传递异步，并发消息来提供有效且可扩展的Sharetrace公式。我们还介绍了消息达到性能，这是时间到达网络拓扑和消息语义的扩展。我们对合成和现实世界接触网络的评估表明，正确的参数值优化了算法的准确性和效率。此外，我们证明，消息达到性能可以准确估计用户对其联系人构成的风险。
Proximity-based contact tracing relies on mobile-device interaction to estimate the spread of disease. ShareTrace is one such approach that improves the efficacy of tracking disease spread by considering direct and indirect forms of contact. In this work, we utilize the actor model to provide an efficient and scalable formulation of ShareTrace with asynchronous, concurrent message passing on a temporal contact network. We also introduce message reachability, an extension of temporal reachability that accounts for network topology and message-passing semantics. Our evaluation on both synthetic and real-world contact networks indicates that correct parameter values optimize for algorithmic accuracy and efficiency. In addition, we demonstrate that message reachability can accurately estimate the risk a user poses to their contacts.
