The Internet of Things scenario is composed of an amalgamation of physical devices. Those physical devices are heterogeneous in their nature both in terms of communication protocols and in data exchange formats. The Web of Things emerged as a homogenization layer that uses well-established web technologies and semantic web technologies to exchange data. Therefore, the Web of Things enables such physical devices to the web, they become Web Things. Given such a massive number of services and processes that the Internet of Things/Web of Things enables, it has become almost mandatory to describe their properties and characteristics. Several web ontologies and description frameworks are devoted to that purpose. Ontologies such as SOSA/SSN or OWL-S describe the Web Things and their procedures to sense or actuate. For example, OWL-S complements SOSA/SSN in describing the procedures used for sensing/actuating. It is, however, not its scope to be specific enough to enable a computer program to interpret and execute the defined flow of control. In this work, it is our goal to investigate how we can model those procedures using web ontologies in a manner that allows us to directly deploy the procedure implementation. A prototype implementation of the results of our research is implemented along with an analysis of several use cases to show the generality of our proposal.
物联网场景由物理设备的混合体组成。这些物理设备在通信协议和数据交换格式方面在本质上是异构的。物联网的出现是作为一个同质化层，使用成熟的网络技术和语义网络技术来交换数据。因此，物联网使这些物理设备能够连接到网络上，它们成为了“网络事物”。考虑到物联网/物联网所支持的如此大量的服务和流程，描述它们的属性和特征几乎已成为必要。有几个网络本体论和描述框架致力于这一目的。例如，SOSA/SSN 或 OWL-S 等本体论描述了网络事物及其用于感知或驱动的过程。例如，OWL-S 补充了 SOSA/SSN，用于描述用于感知/驱动的过程。然而，它的范围还不够具体，无法使计算机程序解释和执行定义的控制流。在这项工作中，我们的目标是研究如何使用网络本体论以允许我们直接部署过程实现的方式来对这些过程进行建模。我们研究结果的原型实现与对几个用例的分析一起实现，以展示我们建议的通用性。
