摘要

人工智能领域的最新进展带来了有希望的新能力,可以大大提高我们在面对不确定性时管理复杂和不断变化的情况的能力。人道主义危机就是这种情况的例证,而社交媒体的普及使其成为最丰富的实时信息来源之一。然而,将大量的社交媒体帖子快速压缩成有用的信息是一项相当困难的任务。在本文中,我们考虑了使用社交媒体报告在人道主义危机管理中提供可靠的实时态势感知的挑战。有效应对这一挑战需要从个人社交媒体帖子的文本和图像中提取相关信息,将这些信息融合到一起,为决策者提供可操作的信息点,并对这些信息的可信度进行评估。我们提出了一个通用的解决方案框架,并讨论了与北约合作开发的一个系统,该系统结合了最先进的深度学习、自然语言处理、计算机视觉和信息融合模型,为人道主义危机后勤支持决策提供可靠、可操作、实时的态势感知。除了技术方法之外,我们还讨论了这个项目的重要实践方面,包括开发和验证过程、在此过程中遇到的挑战,以及学到的关键经验教训。

Supporting Humanitarian Crisis Decision Making with Reliable Intelligence Derived from Social Media Using AI
Abstract Recent advances in the field of artificial intelligence bring promising new capabilities that can substantially improve our ability to manage complex and evolving situations in the face of uncertainty. Humanitarian crises exemplify such situations, and the pervasiveness of social media renders it one of the most abundant sources of real-time information available. However, it is quite a difficult task to condense a body of social media posts into useful information quickly. In this paper we consider the challenge of using social media reports to provide a reliable, real-time situational awareness in the management of humanitarian crises. Effectively addressing this challenge requires extracting only the relevant information out of text and images in individual social media posts, fusing this information together into actionable information points for decision makers, and providing an assessment of the trustworthiness of this information. We propose a general solution framework and discuss a system developed in collaboration with NATO which combines state-of-the-art deep learning, natural language processing, computer vision, and information fusion models to provide a reliable, actionable, real-time situational awareness for supporting decision making in humanitarian crisis logistics. In addition to the technical approach, we also discuss important practical aspects of this project including the development and validation process, challenges encountered along the way, and key lessons learned.
