Semantically rich descriptions of manufacturing machines, offered in a machine-interpretable code, can provide interesting benefits in Industry 4.0 scenarios. However, the lack of that type of descriptions is evident. In this paper we present the development effort made to build an ontology, calledExtruOnt, for describing a type of manufacturing machine, more precisely, a type that performs an extrusion process (extruder). Although the scope of the ontology is restricted to a concrete domain, it could be used as a model for the development of other ontologies for describing manufacturing machines in Industry 4.0 scenarios. The terms of the ExtruOnt ontology provide different types of information related with an extruder, which are reflected in distinct modules that constitute the ontology. Thus, it contains classes and properties for expressing descriptions about components of an extruder, spatial connections, features, and 3D representations of those components, and finally the sensors used to capture indicators about the performance of this type of machine. The ontology development process has been carried out in close collaboration with domain experts.

ExtruOnt：用于描述用于工业4.0系统的制造机器类型的本体

用机器可解释的代码提供的语义丰富的制造机器描述可以在Industry 4.0场景中提供有趣的好处。但是，显然缺乏这种类型的描述。在本文中，我们介绍了构建名为ExtruOnt的本体所进行的开发工作，该本体用于描述制造机器的类型，更确切地说是执行挤压过程（挤压机）的类型。尽管本体的范围仅限于具体领域，但它可以用作开发其他本体的模型，以描述工业4.0场景中的制造机器。ExtruOnt本体的术语提供了与挤出机有关的不同类型的信息，这些信息反映在构成本体的不同模块中。从而，它包含用于表示有关挤出机组件的描述，空间连接，这些组件的特征和3D表示的类和属性，最后是用于捕获有关此类机器性能指标的传感器。本体开发过程是与领域专家密切合作进行的。
