Semantic-Web Supported Knowledge Management System: An Approach to Enhance Collaborative Building Design

This paper focuses on a lightweight ontology-based knowledge management system, which is a main component of IT-CODE, a Semantic Web based virtual workspace for enhancing the collaboration at an early building design stage. Technologies with respect to de facto standards that are proposed by industry group W3C are implemented to develop this knowledge management system. Resource Description Framework (RDF) associated with its Schema (RDFS) is selected as ontology language of the system. RDF(S) with its embedded reasoning techniques provides a rich set of constructs to facilitate the generation of ontologies so that the annotated information can be machine readable. Initiatives taken in the building industry for the evolution of the Semantic Web will be overviewed in this paper. Potential benefits offered by the RDF(S)-based knowledge management system to the building industry will be explained. Approaches of how the knowledge is represented in RDF-based ontology, is shared and retrieved among actors participating in the early design phase of a building project will also be described and illustrated. The paper will conclude with a description of how the early design phase may benefit from IT-CODE and its innovative knowledge management system.
