Towards the ontology-based consolidation of production-centric standards
This is an Author's Accepted Manuscript of an article published in the International Journal of Production Research [© Taylor & Francis], available online at: http://www.tandfonline.com/doi/abs/10.1080/00207543.2011.627885.Production-Âcentric
international
standards
are
intended
to
serve
as
an
important

systems.
As
a
consequence
of
textual-Âbased
definitions
of
concepts
acknowledged
within
these
standards,
their
inability
to
fully

becomes
an
issue

since
a

of

are

to

the

To

this

the

that

Mediation of foundation ontology based knowledge sources
This is the author’s version of a work that was accepted for publication in the journal Computers in Industry [© Elsevier]. Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document. Changes may have been made to this work since it was submitted for publication. A definitive version was subsequently published in Computers and Industry: www.elsevier.com/locate/compindOntologies are helpful in giving interoperable structures to sources of knowledge and information. This interoperability, however, is greatly hindered by the heterogeneity of independently developed ontologies which in turn increases the requirements for mediation systems to reconcile the differences. A core concepts ontology for a certain domain contained by a foundation ontology can be used to alleviate this problem and to facilitate the reconciliation efforts. Possible differences in the use of concepts from the core concepts to model entities in domain ontologies can be prevented by binding the domain ontology developers to some rules. These rules can be particularly useful for domain ontologies requiring some kind of traceability of their concepts in the foundation ontology. The mediation system can then use this traceability to establish similarities between two ontologies. Software applications, like the one explained in this paper, can then be developed to perform the mediation task automatically and accurately

A narrative in three acts: Using combinations of image schemas to model events
Image schemas have been proposed as conceptual building blocks corresponding to the hypothesised most fundamental embodied experiences. We formally investigate how combinations of image schemas (or 'image schematic profiles') can model essential aspects of events, and discuss benefits for artificial intelligence and cognitive systems research, in particular concerning the role of such basic events in concept formation. More specifically, as exemplary illustrations and proof of concept the image schemas Object, Contact, and Path are combined to form the events Blockage, Bouncing, and Caused-Movement. Additionally, an outline of a proposed conceptual hierarchy of levels of modelling for image schemas and similar cognitive theories is given
Extending product lifecycle management for manufacturing knowledge sharing
This article was published in the Proceedings of the Institution of Mechanical Engineers Part B - Journal of Enginering Manufacture [© Sage] and the definitive version is available at: http://dx.doi.org/10.1177/0954405412461741Product lifecycle management provides a framework for information sharing that promotes various types of decisionmaking
procedures. For product lifecycle management to advance towards knowledge-driven decision support, then this
demands more than simply exchanging information. There is, therefore, a need to formally capture best practice
through-life engineering knowledge that can be fed back across the product lifecycle. This article investigates the interoperable
manufacturing knowledge systems concept. Interoperable manufacturing knowledge systems use an expressive
ontological approach that drives the improved configuration of product lifecycle management systems for manufacturing
knowledge sharing. An ontology of relevant core product lifecycle concepts is identified from which viewpoint-specific
domains, such as design and manufacture, can be formalised. Essential ontology-based mechanisms are accommodated
to support the verification and sharing of manufacturing knowledge across domains. The work has been experimentally
assessed using an aerospace compressor disc design and manufacture example. While it has been demonstrated that the
approach supports the representation of disparate design and manufacture perspectives as well as manufacturing knowledge
feedback in a timely manner, areas for improvement have also been identified for future work
Exploiting unified modelling language (UML) as a preliminary design tool for Common Logic-based ontologies in manufacturing
This is an Accepted Manuscript of an article published by Taylor & Francis in International Journal of Computer Integrated Manufacturing on 08/06/2012, available online: http://dx.doi.org/10.1080/0951192X.2012.688142.This paper proposes a particular method which utilises the unified modelling language (UML) as a design visualisation tool for modelling ontologies based on the Common Logic knowledge representation language. The use of this method will enable Common Logic ontological concepts to be more readily accessible to general engineers and provide a valuable ontology design aid. The method proposed is explored using the knowledge frame language (KFL) which provides constructs to facilitate ontology building and is built on Common Logic. The major constructs of KFL are briefly defined and a description of how each construct may be represented in UML is given. Examples are presented showing how the constructs may be modelled in UML and a Common Logic-based implementation founded on a UML design is illustrated and discussed. The manufacturing domain is utilised as an experimental basis for demonstrating the proposed method
