Ifcowl: A case of transforming express schemas into ontologies

Abstract Ontologies have been successfully applied as a semantic enabler of communication between both users and applications in fragmented, heterogeneous multinational business environments. In this paper we discuss the underlying principles, their current implementation status, and most importantly, their applicability to problems in the building information modeling domain. We introduce the development of an ontology for the building and construction sector based on the industry foundation classes. We discuss several approaches of lifting modeling information that is based on the express family of languages for data modeling onto a logically rigid and semantically enhanced ontological level encoded in the W3C Ontology Web Language. We exemplify the added value of such formal notation of building models by providing several examples where generic query and reasoning algorithms can be applied to problems that otherwise have to be manually hard-wired into applications for processing building information. Furthermore, we show how the underlying resource description framework and the set of technologies evolving around it can be tailored to the need of distributed collaborative work in the building and construction industry.

Architectural Design-by-Features

Design tasks, in particular architectural design tasks, have been found hard to support by means of computers. The main reason for this is that design is a problem solving process, which requires a dynamic way of handling information involved in the design process. The research presented in this paper focuses on this aspect of CAAD: the support of design tasks with dynamic, flexible information modelling techniques. The basic concepts for the developed approach is taken from the field of Feature-based modelling. We briefly review these concepts and then interpret and transport them to the context of architectural design. In defining types of Features, a distinction is made between domain-specific Features and generic Features for which we propose a classification. A framework for the definition and modelling of Features is discussed as well as a prototype Feature-based Modelling Shell based on this framework.

Evaluating design alternatives using conjoint experiments in virtual reality

In this paper the authors describe the design of an experiment based on conjoint measurement that explores the possibility of using the Internet to evaluate design alternatives. These design alternatives are presented as panoramic views, and preferences are measured by asking subjects which alternative they prefer from a choice set of design alternatives. The approach is illustrated by using the design of office spaces as an example.

A FEATURES FRAMEWORK FOR ARCHITECTURAL INFORMATION

Supporting architectural design by means of computers requires the development of formal representations of design information. The paper reviews the way information is dealt with in design and describes this as the dynamic nature of design. This leads to the notion that an information model should evolve along with the development of a design. Keywords in this evolution are extensibility and flexibility of information models. The approach developed to fulfil these requirements is based on the techniques of Feature-Based Modelling of which the concepts and potentials are discussed with respect to their relevance for the area of architectural design. Subsequently, a framework is presented for the development of architectural Feature-based modelling systems. This framework includes a layered schema for information definition that provides basic classes of Feature types and the conditions for extension and flexible manipulation of both conceptual and actual information models. Relationships between the entities in these models are discussed in more detail and an approach is introduced for supporting the modelling of relationships that are not defined at the conceptual, or typological, level.

Feature-Based High Level Design Tools

The VR-DIS project aims to provide design support in the early design stage using a Virtual Reality environment. The initial brief of the design system is based on an analysis of a design case. The paper describes the process of analysis and extraction of design knowledge and design concepts in terms of Features. It is demonstrated how the analysis has lead to a classification of design concepts. This classification forms one of the main specifications for the VR-based design aid system that is being developed in the VR-DIS programme. The paper concludes by discussing the particular approach used in the case analysis and discusses future work in the VR-DIS research programme.
