How semantics can improve engineering processes: A case of units of measure and quantities
MetadataShow full item record
Science and engineering heavily depend on the ability to share data and models. Ontologies provide such standards. We have found that existing ontologies only define subsets of the necessary concepts and relations. We therefore propose a new ontology, called OM (Ontology of units of Measure and related concepts). Moreover, to make OM available for arbitrary software systems, we have developed a number of web services that offer a standardized interface. Three applications demonstrate the usefulness of OM and its services. First, a web application checks dimension and unit consistency of formulas. Second, an engineering application for agricultural supply chains computes product respiration quantities and measures. Third, a Microsoft Excel add-in assists in data annotation and unit conversion.
