TL;DR: This paper proposes an approach to automatically constructing a large- scale situation ontology by mining large-scale web resources, eHow and wikiHow, which contain an enormous amount of how-to instructions.

TL;DR: The article presents the research of the nature, building and practical role of a Design Ontology as a potential framework for the more efficient product development (PD) data-, information- and knowledge- description, -explanation, -understanding and -reusing.
Abstract: The article presents the research of the nature, building and practical role of a Design Ontology as a potential framework for the more efficient product development (PD) data-, information- and knowledge- description, -explanation, -understanding and -reusing. In the methodology for development of the ontology two steps could be identified: empirical research and computer implementation. Empirical research has included domain documentation analysis (Genetic Design Model System developed by Mortensen 1999), identification of the key concepts and relations between them, and categorisation of the concepts and relations into taxonomies. As an epistemological foundation for the concepts formalisation, The Suggested Upper Merged Ontology (SUMO) proposed by IEEE, was reused. As the result of the previously described process, the ontology content has been categorised into six main subcategories divided between physical and abstract world. As a next step the computer thesaurus has been created. Using the thesauri...

TL;DR: An overview of the PSL Ontology is given, including its formal characterization as a set of theories in first-order logic and the concepts that are axiomatized in these theories.
Abstract: The Process Specification Language (PSL) has been designed to facilitate correct and complete exchange of process information among manufacturing systems. We give an overview of the PSL Ontology, including its formal characterization as a set of theories in first-order logic and the concepts that are axiomatized in these theories.
