Reliable and interoperable computational molecular engineering: 2. Semantic interoperability based on the European Materials and Modelling Ontology

Abstract

The European Materials and Modelling Ontology (EMMO) is a top-level ontology that was designed by the European Materials Modelling Council (EMMC) to facilitate semantic interoperability between platforms, models, and tools in computational molecular engineering, integrated computational materials engineering, and related applications of materials modelling and characterization. Additionally, domain ontologies exist based on data technology developments from specific platforms. The present work discusses the ongoing work on establishing a European Virtual Marketplace Framework, into which diverse platforms can be integrated. It addresses common challenges that arise when marketplace-level domain ontologies are combined with a top-level ontology like the EMMO by ontology alignment.

Ontologies for the Virtual Materials Marketplace

“…The EVMPO and the EMMO are connected by the EVI module which is specifically designed for this purpose. Ongoing work on ontology alignment [15] will extend this module to create additional connections between marketplace-level ontologies and the EMMO.…”

“…1. Therein, if an ontology references concepts (e.g., class definitions) from another semantic asset, an arrow is shown, leading from the component of the architecture where the concept is used to the component where it is defined; accordingly, e.g., class definitions from the European Virtual Marketplace Ontology (EVMPO) [15] are employed, and hence pointed to, by all other ontologies developed in VIMMP. At the marketplace level, focusing on service, platform, and simulation interoperability, this includes eight components which are described below:…”

“…It is structured as follows: In Section 2, we briefly describe the marketplace services and correspondigly introduce the related marketplace-level ontologies; then, Section 3 summarizes the role of the ontologies in data management, including data ingest and data retrieval. In Section 4, it is discussed how the present work can support the efforts of the EMMC to enable inter-platform interoperability by alignment with the European Materials and Modelling Ontology (EMMO), a communitygoverned top-level ontology for modelling and characterizing materials [13,15], before drawing conclusions in Section 5.…”

AI Concepts for System of Systems Dynamic Interoperability

“…Semantic interoperability is the interoperability of structured information artifacts, or semantic assets [34,35]. The components of semantic assets gain meaning from their structure and the context in which they are used, e.g., a list of two floating point numbers gain the meaning of coordinates when used in the context of geography.…”
