title	Knowledge management by information mining
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 533-545
summary	Novel information mining method dealing with soft computing is described. By this method, in the first step, receptive fields of design information are identified so that connections among various design aspects are structured. By means of this, complex relationships among various design aspects are modeled with a paradigm, which is non-parametric and generic. In the second step, the structured connections between various pairs of aspects are graded according to the relevancy to each other. This is accomplished by means of sensitivity analysis, which is a computational tool operating on the model established and based on a concept measuring the degree of dependencies between pairs of quantities. The degree of relationships among various design aspects so determined enables one to select the most important independent aspects in the context of design or decision-making process. The paper deals with the description of the method and presents an architectural case study where numerical and as well as non-numerical (linguistic) design information are treated together, demonstrating a ranked or elective information employment which can be of great value for possible design intervention during reconstruction.

title	Quantifying the Qualitative Design Aspects
doi	https://doi.org/10.52842/conf.ecaade.2001.111

summary	Architecture is a mixture of art and technique. This implies that the architect deals not only with engineering aspects that can be easily quantified and thereafter processed, but deals with aesthetics as well which is in first place qualitative and therefore rather difficult to estimate and numerically represent. As an example, in such cases, these ‘qualitative quantities’ are expressed in linguistic form which should be somehow expressed in numerical form in order to treat such data by powerful and conclusive numerical analysis methods. Expressions such as: bright colour, light room, large space are some of these examples. These expressions are fuzzy concepts whose actual interpretation is hidden and all of them together attach a qualitative value to a certain space. To deal with such information the emerging technologies of the last decade can provide an important aid. One of them is the soft computing technology that can deal with such soft data. In this paper, based on the case studies, we explain the potential of using soft computing techniques.

title	The impact of computer-based design tools for daylighting simulation and prediction for a built environment
doi	https://doi.org/10.52842/conf.caadria.2001.169
source	CAADRIA 2001 [Proceedings of the Sixth Conference on Computer Aided Architectural Design Research in Asia / ISBN 1-86487-096-6] Sydney 19-21 April 2001, pp. 169-179
summary	This paper investigates the application of computer daylighting simulation to provide qualitative assessment and comparison for designers to improve the built environment especially for non-technical architecture students. A comprehensive study was carried out to evaluate different daylighting design tools and to identify the limitation of current systems in the academic field. The paper will focus mainly on the dynamic information exchange between scientific visualization and the design decision-making process. Both architectural design studio environment and practical design problems in the real world setting were experimented and evaluated. Two case studies are presented: a proposed gallery space for a museum, and a detail architectural design of a community church. Architectural design alterations are proposed, simulated and discussed. The recursive feedback of the designers are studied and documented. Through a combination of qualitative assessment and comparison, designers can evaluate and compare different design options in the computing environment before implementing in the real world situation.

title	Qualitative Spatial Reasoning Based on Algebraic Topology
source	J. S. Gero, B. Tversky and T. Purcell (eds), 2001, Visual and Spatial Reasoning in Design, II - Key Centre of Design Computing and Cognition, University of Sydney, Australia
summary	Several formalisms have been proposed for qualitativereasoning about regions and their topological relations in space. Theseformalisms, based on pairwise relations, do not allow sufficientlypowerful inferences to be used for spatial reasoning tasks such asplanning a collision-free path. In this paper, I show how consideringrelations between region triples, much more powerful reasoningtechniques become possible. I show in particular that in twodimensions, purely topological reasoning is sufficient to compute aminimal place graph which represents all minimal and maximal regioncombinations, as well as all minimal paths between them. I illustratehow this could be applied to motion planning, showing that in spite ofits qualitative nature, the formalism is powerful enough to solveproblems of practical interest.

source	J. S. Gero, B. Tversky and T. Purcell (eds), 2001, Visual and Spatial Reasoning in Design, II - Key Centre of Design Computing and Cognition, University of Sydney, Australia
summary	In this paper we construct an information-theoretic model ofarchitectural drawings. This model is then used to quantify and measurethe complexities and similarities of drawings. The approach is appliedwithin a linear qualitative shape representation but can be generalized toother types of representation. The descriptive and analytic power of theproposed methods are demonstrated by studying the time evolution ofthe architectural plans produced by Aalto and Kahn and by comparingthem to each other.

title	Is a Figure-Concept Binary Argumentation Pattern Inherent in Visual Design Reasoning?
source	J. S. Gero, B. Tversky and T. Purcell (eds), 2001, Visual and Spatial Reasoning in Design, II - Key Centre of Design Computing and Cognition, University of Sydney, Australia
summary	This paper is based on the assumption that because designingis aimed at specifying configurations of entities, designers mustmanipulate forms and shapes and they must resort to visual reasoning todo so. Visual reasoning in designing is seen as the interplay betweenfigural and conceptual reasoning, such that the one supports andcontinues the other in order to arrive at a configuration that is valid interms of all the requirements it is to satisfy. We use protocol analysis toexplore the bond between conceptual and figural reasoning at two levelsof cognitive operation – that of the design move and that of theargument that is its building block. We conclude that the two modes ofreasoning are equi-present in designing; they describe a binary systemcharacterized by high frequency shifts between figure and concept.

title	Emergence in a Recognition Based Drawing Interface
source	J. S. Gero, B. Tversky and T. Purcell (eds), 2001, Visual and Spatial Reasoning in Design, II - Key Centre of Design Computing and Cognition, University of Sydney, Australia
summary	People perceive patterns in representations, patterns that may nothave been initially intended. This phenomenon of emergence is deemed toplay an important role in design. Computer based design assistants canand should support this human perceptual ability, using patternrecognition to anticipate human designers’ perception of emergent shapesand supporting the subsequent manipulation of and reasoning with theseshapes as part of the design. Freehand drawing programs with gesturerecognition are well positioned to implement shape emergence. Supportfor emergent shapes in the Back of an Envelope system is described.

title	Analysis and the descriptive approach
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	The rise of consciousness concerning the quality of working and living conditions has been a permanent though frequently underplayed theme in architecture and building since the reconstruction period. It has led to an explosive growth of programmatic requirements on building behaviour and performance, thus also stimulating the development of design analysis. The first stage of development was characterized by the evolution of prescriptive systems. These reversed the structure of pre-existing proscriptive systems into sequences of known steps that should be taken in order to achieve adequate results. Prescriptive systems complemented rather than replaced proscriptive ones, thereby creating an uncertain mixture of orthodoxy and orthopraxy that failed to provide design guidance for improving design performance and quality.The second stage in the development of design analysis focuses on descriptive methods and techniques for analyzing and supporting evaluation. Technologies such as simulation and scientific visualization are employed so as to produce detailed, accurate and reliable projections of building behaviour and performance. These projections can be correlated into a comprehensive and coherent description of a building using representations of form as information carriers. In these representations feedback and interaction assume a visual character that fits both design attitudes and lay perception of the built environment, but on the basis of a quantitative background that justifies, verifies and refines design actions. Descriptive analysis is currently the most promising direction for confronting and resolving design complexity. It provides the designer with useful insights into the causes and effects of various design problems but frequently comes short of providing clear design guidance for two main reasons: (1) it adds substantial amounts of information to the already unmanageable loads the designer must handle, and (2) it may provide incoherent cues for the further development of a design. Consequently the descriptive approach to analysis is always in danger of been supplanted by abstract decision making.One way of providing the desired design guidance is to complement the connection of descriptive analyses to representations of form (and from there to synthesis) with two interface components. The first is a memory component, implemented as case-bases of precedent designs. These designs encapsulate integrated design information that can be matched to the design in hand in terms of form, function and performance. Comparison between precedents with a known performance and a new design facilitate identification of design aspects that need be improved, as well as of wider formal and functional consequences. The second component is an adaptive generative system capable of guiding exploration of these aspects, both in the precedents and the new design. The aim of this system is to provide feedback from analysis to synthesis. By exploring the scope of the analysis and the applicability of the conclusions to more designs, the designer generates a coherent and consistent collection of partial solutions that explore a relevant solution space. Development of the first component, the design case-bases, is no trivial task. Transformability in the representation of cases and flexible classification in a database are critical to the identification and treatment of a design aspect. Nevertheless, the state of the art in case-based reasoning and the extensive corpus of analysed designs provide the essential building blocks. The second component, the adaptive generative system, poses more questions. Existing generative techniques do not possess the necessary richness or multidimensionality. Moreover, it is imperative that the designer plays a more active role in the control of the process than merely tweaking local variables. At the same time, the system should prevent that redesigning degenerates into a blind trial-and-error enumeration of possibilities. Guided empirical design research arguably provides the means for the evolutionary development of the second component.

title	Using Evolutionary Methods for Design Case Adaptation
doi	https://doi.org/10.52842/conf.acadia.2001.180
source	Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 180-191
summary	Case-based reasoning (CBR) provides a methodology for directly using previous designs in the development of a new design. An aspect of CBR that is not well developed for designing is the combination and adaptation of previous designs. The difficulty with this aspect of case-based design is partly due to the extensive amounts of specialised knowledge needed to select the appropriate features of a previous design to include in the new design and the adaptation of these features to fit the context of a new design problem. In this paper we present a design process model that combines ideas from CBR and genetic algorithms (GA’s). The CBR paradigm provides a method for the overall process of case selection and adaptation. The GA paradigm provides a method for adapting design cases by combining and mutating their features until a set of new design requirements and constraints are satisfied. We have implemented the process model and illustrate the model for residential floor plan layout. We use a set of Frank Lloyd Wright prairie house layouts as the case base. The constraints used to determine whether new designs proposed by the process model are acceptable are taken from feng shui, the Chinese art of placement. This illustration not only clarifies how our process model for design through the evolutionary adaptation of cases works, but it also shows how knowledge sources with distinct origins can be used within the same design framework.

title	Destination: Practice – Towards a maintenance contract for the architect’s degree
doi	https://doi.org/10.52842/conf.acadia.2001.090
source	Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 090-099
summary	Addressing the subject of Case-Based Reasoning (CBR) in architectural design, we present a Web-based design assistant for student- and professional architects called DYNAMO. Its main objective is to initiate and nurture the life-long process of learning from (design) experience as suggested by CBR’s cognitive model. Rather than adopting this model as such, DYNAMO extrapolates it beyond the individual by stimulating and intensifying several modes of interaction. One mode – the focus of this paper – concerns the interaction between the realm of design education and the world of practice. DYNAMO offers a platform for exchanging design efforts and insights, in the form of cases, between both parties, which perfectly chimes with the current tendency towards life-long learning and continuing education. Just like our university advises graduates to ‘Take a maintenance contract with your degree’, architecture schools may encourage recently qualified architects to subscribe to DYNAMO. To what extent the tool can fulfill this role of maintenance contract is discussed at the end of the paper, which reports on how DYNAMO was used and appreciated by professional architects at different levels of expertise.

title	EQUAL: a case-based contractor prequalifier
source	Automation in Construction 10 (4) (2001) pp. 443-457
summary	Many researchers have observed that contractor prequalification relies heavily on expert judgement. Experiential judgement is required in decision situations when it would be too costly to measure a large amount of information quantitatively and it is also invaluable in providing shortcuts for complex tasks. However, the quality of heuristic knowledge depends upon the experiences of the decision-makers. The development and use of a case-based reasoning (CBR) system can help decision-makers to produce more reliable and expeditious decisions for contractor prequalification. An Expert preQUALifier –– EQUAL –– has been developed using the CBR approach. This paper describes the components of EQUAL and illustrates the functionality and operation of the system through a trial run with hypothetical cases. The results of testing reveal that experts were satisfied with the accuracy and overall performance of EQUAL, and CBR approach is suitable for modeling the contractor prequalification domain.

title	A Case with a View - Towards an Integration of Visual and Case-Based Reasoning in Design
doi	https://doi.org/10.52842/conf.ecaade.2001.346
source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 346-341
summary	Despite the long-term effort to establish the theoretical foundations for Case-Based Reasoning (CBR) in design, it appears that additional theoretical efforts are needed in order to achieve the promise of this affinity. In this paper we argue that visual reasoning, is a fundamental attribute of architectural design, and therefore combining it with CBR may provide significant results both for the field of design thinking as well as for the field of CAAD. This paper focuses on reformulating theoretical foundations for CBR in design by incorporating insights from studies in fields like visual imagery and creativity, where visual reasoning is recognized to play a key role. Within classical CBR research, however, visual reasoning has not received much attention until now. Instead, researchers have concentrated on traditional issues and topics in CBR such as indexing, retrieval and adaptation. The second part of the paper therefore switches attention to how these traditional issues may benefit from integrating Case-Based with visual reasoning.

doi	https://doi.org/10.52842/conf.ecaade.2001.092
source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 92-97
summary	This paper discusses methods for information management through the rational application of IT within collaborative design. We explore the possible integration of the platforms of case-based reasoning and information structures. We examine the potential combination of existing techniques (CAD-tools, word processors, general applications, WWW) and standards (IFC, national classification systems) into a system for information management. We focus on the designers’ use of heterogeneous information and the further development of a prototype based on product-model and process-model technology. Today, XML helps us structure various kinds of information before the system performs case-based reasoning sessions. The aim is to promote efficient and flexible information management in a casebased design process. Through the use of standardized product models, this information will be sharable and suitable for reuse and feedback. The more often the information is reused, the more general and adaptable it becomes i.e. it evolves. This scenario requires, though, efficient information management in the design office: a quality system for evaluating the information for reuse, consequent use of standardized product models and IT.

source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 182-189
summary	There is limited research and discussion on pedagogical approaches in architectural education, simply because it is considered as one of the “unimportant” areas that researchers “do not bother studying” (Teymur, 2001). Problem Based Learning has been known to provide competent graduates in other professional disciplines, and, consequently, there have been attempts to utilise the same pedagogical approach in architectural education where PBL is seen as a potential solution to the problems encountered in architectural education. This paper critically reviews PBL implementations at TU Delft Netherlands and Newcastle University, N.S.W. Australia and draws conclusions with particular respect to the teaching of architectural computing

summary	This paper describes VR Sketchpad, a pen-based computing environment for inputting and locating 3D objects in a virtual world. Designer can use the transparency layers to quickly trace and extract any image underlay from other application software. The 3D scene generation has three levels of complexity: simple extrusion of any drawn lines of shapes (i.e., straight or curved wall and column extrusion), solid modelling from a given geometric object representation (spheres, cones and boxes), and complex configuration with objects from graphics library (furniture layout).

summary	Shapes are equal if the spatial relations between their parts areequal. But spatial relations are equal if shapes characterizing the relationare equal. This recursive nature of shape and shape relations isexamined. A repeated shape has distinct parts each equal and in one of aspecified set of spatial relations to another part. A symmetrical shapehas the same spatial relation to each part of some repeated shape.Repeated shapes are simple examples of generated shapes but can showintricate behaviour and indicate the problems of predicting spatialproperties in generative shapes.

title	Space as a Basis for Reasoning
source	J. S. Gero, B. Tversky and T. Purcell (eds), 2001, Visual and Spatial Reasoning in Design, II - Key Centre of Design Computing and Cognition, University of Sydney, Australia
summary	We use space as a basis for reasoning whenever we use aspatial representation of a nonspatial concept to make decisions orinferences. From a psychological perspective, our tendency to create andreason fluidly from spatial models is somewhat surprising, becauseusing a spatial model to reason involves creating correspondencesbetween two semantically unrelated concepts: space, and something thatisn’t space, whether that be time, performance, or the desirability of anew job. Our proficiency in using space as a basis for reasoning reliesour abilities to detect similarities in the structures of very differentconcepts. In this paper I discuss two types of similarities between spaceand nonspatial concepts and describe how those similarities influencereasoning from spatial representations.

summary	This paper outlines the evolution of digital management systems used in the School of Architecture and building at Deakin University from 2001 to the present. These systems have been implemented to support a curriculum development programme in the design, construction and computing units. Two school-based information management systems are discussed in depth: low-tech network submission system and Bentley Systems Inc’s ProjectWise. Early experiences in using a universitybased system are also reported on. Lessons learnt from three years experience in managing digital resources for design education have informed the development of a growing digital culture in the architectural and construction management curricula. Whilst digital curriculum design and management systems supporting this curriculum have been developed effectively in this school, full optimization of IT to enhance design education is reliant on fundamental changes within traditional academic culture.
