一种基于事件的情境表征方法
An Event Based Approach To Situational Representation
摘要：
许多应用领域需要表示相互关联的真实世界活动和/或不断变化的物理现象。例如，在危机应对领域，人们可能对表示正在发生的危机的状态感兴趣（例如，森林火灾）、疏散和交通管制等应对活动的进展以及危机现场的状况。然后，这种情况表示可以用于支持多种应用，包括情况监视、分析和规划。在本文中，我们提出了一个基于事件的情况下，事件被定义为特定领域的空间和时间的重要事件表示。我们认为，事件提供了一个统一的和强大的抽象构建态势感知应用程序。我们确定的挑战，在建立一个事件管理系统（EMS），传统的数据和知识管理系统被证明是有限的，并建议可能的方向和技术，以解决这些挑战。
英文摘要：
Many application domains require representing interrelated real-world activities and/or evolving physical phenomena. In the crisis response domain, for instance, one may be interested in representing the state of the unfolding crisis (e.g., forest fire), the progress of the response activities such as evacuation and traffic control, and the state of the crisis site(s). Such a situation representation can then be used to support a multitude of applications including situation monitoring, analysis, and planning. In this paper, we make a case for an event based representation of situations where events are defined to be domain-specific significant occurrences in space and time. We argue that events offer a unifying and powerful abstraction to building situational awareness applications. We identify challenges in building an Event Management System (EMS) for which traditional data and knowledge management systems prove to be limited and suggest possible directions and technologies to address the challenges.
