Towards Semantic Interoperability in Virtual Organisations

Abstract: Virtual organisations (VOs) are amongst the most advanced forms of doing business to date. Their emergence and growing capacities are closely related to the networking and collaboration capabilities provided by a supporting ICT infrastructure. However, whilst considerable progress in the development of such infrastructures has been achieved over the years, interoperability still remains a major challenge. In this paper we analyse the nature of the semantic interoperability problem, review the state of the art, and derive a set of requirements. On that basis, we propose a novel semantic interoperability framework for VOs, utilising current semantic Web technologies, and suggest possible design and implementation methods for its achievement. Reported is in-house work of the authors as well as on-going research in the frames of the EU project InteliGrid (IST-2004-004664).

Provenance Metadata for Shared Product Model Databases

Abstract: The process of saving metadata committed to track all changes to some data, is known as ""provenance"". In the AEC/FM sector provenance data can be exploited for tracking all interactions of different users between each other and with parts of data. For a particular application, we need to consider which metadata are essential for future queries and who is going to use these. The IFC standard already contains some provenance concepts in its entity structure. We have considered these provenance concepts to build a provenance tracking software. The provenance ontology server was developed by using the OWL ontology language, already available IFC concepts and some complementary concepts that we had to include for the sake of generality of our implementation. The developed prototype allows us to upload an IFC file to a web enabled service that parses it and saves instances of retrieved concepts for later queries, according to the ontology we have defined.""

ENERGY EFFICIENCY ALONG THE BUILDING LIFE-CYCLE: A CONCEPTUAL MODEL FOR KNOWLEDGE AND INFORMATION EXCHANGE AMONG AEC PROFESSIONALS

Abstract: Building Life-Cycle Assessment (LCA) promotes principles of careful treatment of the environment, preservation of the natural resources and economy in the construction and energy consumption of buildings. Recently, several information systems were developed or upgraded to support LCA. Such systems, however, do not effectively support knowledge exchange among the AEC professionals. In order to address this problem, the possibility to develop an open knowledge base supporting LCA is investigated in this study. Use cases from industry and legislation were collected and analysed. Then a conceptual model is developed by using the Web Ontology Language (OWL). Based on the model an initial knowledge base is populated with instances of new approaches, materials and methodologies related to LCA. This corresponds to key requirements from industry and demonstrates that the approach has the potential to facilitate greater knowledge exchange among AEC professionals in all LCA phases.
