论文摘要
已经提出了行业〜4.0(I4.0)标准和标准化框架,目的是\ emph {Emph {授权互操作性}在智能工厂中。这些标准可以使智能工厂内部主要组件,系统和过程的描述和交互。由于框架和标准的数量越来越大,对方法的需求越来越多,可以自动分析I4.0标准的景观。标准化框架根据标准将其功能分类为层和尺寸。但是,类似的标准可以在整个框架上以不同的方式分类,从而产生互操作性冲突。已经提出了依赖本体和知识图的基于语义的方法,以代表标准,已知的关系以及根据现有框架的分类。尽管信息丰富,但I4.0景观的结构化建模仅为检测互操作性问题提供了基础。因此,需要基于图的分析方法来利用这些方法编码的知识,才能发现标准之间的一致性。我们根据社区分析研究标准和框架之间的相关性,以发现有助于应对标准之间互操作性冲突的知识。我们使用知识图嵌入来自动创建这些社区,从而利用现有关系的含义。特别是,我们专注于识别相似标准,即标准社区,并分析其特性以检测未知的关系。我们在知识图上使用trans $^*$嵌入模型的嵌入式模型来评估我们的方法。我们的结果是有希望的,建议可以准确检测到标准之间的关系。
Industry~4.0 (I4.0) standards and standardization frameworks have been proposed with the goal of \emph{empowering interoperability} in smart factories. These standards enable the description and interaction of the main components, systems, and processes inside of a smart factory. Due to the growing number of frameworks and standards, there is an increasing need for approaches that automatically analyze the landscape of I4.0 standards. Standardization frameworks classify standards according to their functions into layers and dimensions. However, similar standards can be classified differently across the frameworks, producing, thus, interoperability conflicts among them. Semantic-based approaches that rely on ontologies and knowledge graphs, have been proposed to represent standards, known relations among them, as well as their classification according to existing frameworks. Albeit informative, the structured modeling of the I4.0 landscape only provides the foundations for detecting interoperability issues. Thus, graph-based analytical methods able to exploit knowledge encoded by these approaches, are required to uncover alignments among standards. We study the relatedness among standards and frameworks based on community analysis to discover knowledge that helps to cope with interoperability conflicts between standards. We use knowledge graph embeddings to automatically create these communities exploiting the meaning of the existing relationships. In particular, we focus on the identification of similar standards, i.e., communities of standards, and analyze their properties to detect unknown relations. We empirically evaluate our approach on a knowledge graph of I4.0 standards using the Trans$^*$ family of embedding models for knowledge graph entities. Our results are promising and suggest that relations among standards can be detected accurately.
