Managing virtual organization processes by semantic web ontologies

Abstract: Interoperability within Virtual Organisations (VOs) is still only weakly supported by IT frameworks. Whilst service level interoperability has made remarkable progress since the emergence and the rapid growth of SOA and Grid technology in the last years, business processes – which are the driving force of each VO – still suffer distinct conceptual gaps regarding their decomposition to technical transactions. There exists no detailed approach that would allow describing technical as well as business aspects in a coherent yet flexible and extensible way. This paper presents a newly developed semantic framework that targets this requirement. The conceptual background is followed by an introduction of the developed semantic web ontologies. Based on these definitions, dedicated Ontology Services as well as a set of related end-user applications facilitating semantic technology have been designed and implemented. They are presented in the second part of the paper. Reported are results from the EU project InteliGrid (IST-004664; 2004-2007).

Towards Semantic Grid in Construction Informatics

Abstract: Civil Engineering increasingly requires efficient Virtual Organizations of heterogeneous partners and facilities. Mainly four software architecture paradigms originating from the area of distributed computing have influenced the implementation of supporting software systems for Virtual Organizations: Grid, Peer-to-Peer, Agent as well as Web Service architectures. Each architecture paradigm accounts for different technical aspects that promote the realization of such software systems. The unification of these paradigms towards an integrated architecture has, to date, not been achieved. This keynote paper summarizes the state-of-the-art architecture paradigms and proposes elementary design issues for an integrating architecture. This architecture incorporates ontologies for regulating the communication and interoperability among different services. An application scenario finally demonstrates the usage of such an architecture.

Technology Impact Grid A Model for Strategic IT Planning for Competitive Advantage in Construction

Abstract: The dearth of information on successful cases of strategic use of information technology (IT) in the construction industry is the motivation for an investigation of the use and impact of IT in the construction industries of Spain, France and the United Kingdom. IT has yet to saturate the construction industry. Case studies of six firms in the three European countries which have the experience of using IT in a systematic manner revealed that firms can and do gain competitive advantage and improved business performance from using IT even though there are no explicit policies to gain advantage from IT. The Technology Impact Grid (TIG) was developed from the study. The grid uses two variables, degree of necessity and competitive advantage, to separate current IT into four groups: unwanted necessity, unnecessary investment, blessed potential and strategic treasure. It can be used both as a model for a firm ' s IT position evaluation and as a tool for planning IT acquisition to gain competitive advantage.

Semantic tags for collaboration in construction formalized within a social network framework

Abstract: As construction projects require tracking an ever-increasing number of parameters to operate with suppliers, vendors, and the entire organization of a construction firm, particularly in exchanging, sharing, and integrating information, a semantically rich form to represent information is required. Semantic tags for interoperable construction workflows represent a novel approach to support the exchanging, sharing, and integrating of information. This approach proposes a semantic main form of representation of construction concepts to assist in the communication between actors. The proposed approach is based on the notion of the social network framework. The assumption is that construction actors’ relationships in communicating information can be expressed by patterns of relationships defined in a social network structure. Semantic tags leverage the communication of information within the dynamic social network grid by employing a concept-description that contains metadata. The purpose is to semantically enrich the product or project data. It is expected that the inclusion of additional semantics will overcome inefficiencies within interoperability.

The use of an evaluation matrix to inform the IT strategic planning process for maintenance management

Abstract: The systematic review of information systems is an essential part of the IT strategic planning process. In the context of maintenance management systems this process is normally performed by the maintenance manager. However, many maintenance managers are ill prepared for this task and, as such, new opportunities may be missed or poorly performing computerised systems accepted as the norm. This paper describes the development of a set of practical guidelines in the form of benchmarks which could be used to assist maintenance managers when they review their systems. The benchmarks were based on an evaluation matrix methodology which was used in conjunction with a substantive questionnaire survey of maintenance managers to identify and evaluate the importance and performance of key computerised maintenance functions. The performance of computerised maintenance management systems was evaluated using an evaluation grid and areas of weakness were identified. The potential use of the benchmarks in the strategic review of computerised maintenance management systems is discussed. The paper concludes that the evaluation matrix method can be a useful tool to establish the general level of performance of computerised systems and thus it can inform the IT strategic planning process. In the context of maintenance management systems the evaluation method identified weaknesses in key maintenance processes and these may need to be fundamentally reengineered.

Ontology Based Partial Building Information Model Extraction

Abstract: The research and application of building information modeling (BIM) has been focused on the entire project and the complete life cycle. However, the daily routine on a construction job site has specific requirements and bears certain limitations regarding the usage of information stored in a BIM model. The limitations include scarcity of computing power and trained personnel. One of the requirements is to view a partial model instead of the original, complete model. The partial model may be defined by certain location parameters such as storey numbers and/or building grid lines. In this paper we discuss an ontology-based method to extract a partial model from a complete BIM model. The partial model, as well as the complete model, should be defined in industry foundation classes (IFC) format, which is the widely supported open standard data exchange format for BIM. Theextraction is based on an IFC-based ontology which defines the necessary building blocks of a valid IFC model and the rules of extraction. The whole process is to be implemented as a Web service allowing remote accessibility from various computing platforms. The Web service system could also be linked to other construction software applications for automating construction management functions.
