我们正在观察一个日益增长的趋势，将嵌入式传感器和传感器网络连接到互联网，并在Web上发布其输出。我们认为，这种发展是物联网的先驱，它提供了现实世界的对象，并放置了一个Web存在，不仅包含这些实体的静态描述，而且还包含它们的实时状态。正如文档搜索已经成为网络上最受欢迎的服务之一，我们认为，对现实世界实体的搜索（即，人、地、物）将变得同样重要。然而，与当前Web上的大多数静态文档相比，传感器捕获的真实世界实体的状态是高度动态的。因此，搜索具有特定状态的真实世界实体是一个具有挑战性的问题。在本文中，我们定义的根本问题，概述了可能的解决方案的设计空间，并调查相关的现有方法进行分类，根据他们的设计空间。我们还提出了一个案例研究的现实世界中的搜索引擎称为Dyser设计的作者。
We are observing an increasing trend of connecting embedded sensors and sensor networks to the Internet and publishing their output on the Web. We believe that this development is a precursor of a Web of Things, which gives real-world objects and places a Web presence that not only contains a static description of these entities, but also their real-time state. Just as document searches have become one of the most popular services on the Web, we argue that the search for real-world entities (i.e., people, places, and things) will become equally important. However, in contrast to the mostly static documents on the current Web, the state of real-world entities as captured by sensors is highly dynamic. Thus, searching for real-world entities with a certain state is a challenging problem. In this paper, we define the underlying problem, outline the design space of possible solutions, and survey relevant existing approaches by classifying them according to their design space. We also present a case study of a real-world search engine called Dyser designed by the authors.
