本体论为知识的表示、共享和重用开辟了新的途径。本文是基于合作研究中心（CRC）Transregio 30内的调查。在CRC中，开发并分析了热机械耦合过程。它们提供了生产功能性分级组件的可能性。功能分级是对材料微观结构进行有针对性的、可再现的调整，目的是建立组件的宏观性能。目标是通过至少一个空间维度实现微观结构变化的稳定进展。为了支持制造系统的产品分级性能的规划，我们开发了一个专家系统。专家系统是模拟专家推理的软件。我们打算的专家系统的组成部分之一是一个本体。它帮助研究人员使用和重复使用所获得的CRC知识，以及CRC内不同项目之间的沟通。在本文中，我们解释了预期的专家系统的体系结构，以及它的元素，特别强调本体论。然后我们解释了本体论的发展基于知识提取和表示。
Ontologies open new ways for representing, sharing and reusing knowledge. This paper is based on the investigations within the Collaborative Research Centre (CRC) Transregio 30. In the CRC, thermomechanically coupled processes are developed and analyzed. They provide the possibility to produce functional graded components. Functional gradation is the targeted and reproducible adaptation of a material microstructure with the intention of establishing the macroscopic properties of the component. The objective is the steady progress of the microstructure ́s variation through at least one spatial dimension. To support the manufacturing system’s planning of products with graded properties, we develop an expert system. An expert system is a software which emulates the reasoning of an expert. One of the components of our intended expert system is an ontology. It assists researchers with the use and reuse of the acquired knowledge of the CRC, as well as with communication between the different projects within the CRC. In this paper we explain the architecture of the intended expert system as well as its elements, placing special emphasis on the ontology. Then we explain the ontology ́s development based on knowledge extraction and representation.
