title Learning Through Structural Activity in Collaborative Computer-Aided Design
source CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 355-360
summary The role of structural activities and other solution searching activities in design learning and problem solving have been identified in laboratory studies of problem solving and also in case studies of design teaching.. In laboratory studies, students have solved creative problems collaboratively under various communication conditions. The case studies follow students working on the same problem under two conditions – one group is taught using traditional face-to-face teaching while the other group is additionally supported by a textbased web board. This paper review findings from three experiments from which we can see that students producing above average solutions involved more structural activities than the mediocre cases. These successful cases engaged in textual expression of their design solutions. Computer tools for design should therefore support multiple representations of design work.

title SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.
source Proceedings of Collaborative Decision-Support Systems Focus Symposium, 30th July, 2002; under the auspices of InterSymp-2002, 14° International Conference on Systems Research, Informatics and Cybernetics, 2002, Baden-Baden, pg. 27-44.
summary The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article.

Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components.

Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

title Architectural Meaning in the Existing Architectural Notations - The Technologies for Interoperable Architectural Data Management
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 230-237
summary The paper presents results of investigations upon possible representations of architectural objects containing ‘architectural meaning’. Five groups of such existing representations are analyzed briefly: (1) structural EXPRESS–based definitions, (2) object EXPRESS- and IFC- based notations, (3) XML-based notations, (4) experimental ones, and (5) binary notations. The working taxonomy of the notations is presented and their shortcomings are mentioned. The potential of XML notations for CAD data has been recognized by software vendors and standard organizations all over the world. Many corporations and standardization bodies are developing XML-based notations of CAD data, focusing on interoperability problems. Some of these notations are becoming standards (aecXML, i-drop), influencing the development of all CAAD industry. There are some main groups of problems with the existing commercial standards: Lack of ‘open’ data in its ‘open’ context, lack of architectural meaning in commercial notations, problems with simpler intuitive standards for notation of conceptual design data in early design stages, too complex data semantics, too atomized data, and richness of the data structures. The problems are taken under consideration in order to discuss the present state of architectural standards. Nowadays architects are forced to work with semi-architectural notations, lacking their essence, i.e. lacking methods to describe elements of cultural heritage connected to geometry forms. Instead of language of architecture they deal with virtual cyber-slang.

title Urban Body Mutations through the Use of the Network Configuration

summary Taking as a starting point the hypotheses that the urban body is a self-adapted ecology made of material and non-material components (Bateson, 1972), relationships between elements are examined in an attempt to destabilize the static division of matter and idea and to inquire into those relationships that determine the structural coupling (Maturana, 2002) between body and environment, as well as the constitution of the body itself. Contemporary technology is used in order to trace these alterations and the urban body is examined as a network configuration. The importance of the methodology adopted by the current research lies in the fact that social and economic factors merge with spatial characteristics, allowing for a visualization and re-interpretation of the urban body mutations based on self-adapted reconfigurations and for a prediction of the structural alterations made possible through the reconfiguration of the synaptic forces between elements.

title Elitism, IT and the Modern Architect Opportunity or Dilemma
source Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 97-109
summary Information Technology (IT) is impacting architecture dramatically in process and form. Often thecurrent transformation of architecture is difficult to analyze and frequently we see confusion and anxietyregarding uncertainties for the future of the architect as designer and project leader. The currentpotentiality for new exotic form (i.e. product) is mesmerizing; however, in the current context, lessobvious issues and pertinent questions are emerging for the profession. What is the mission of theprofession? What will keep us relevant in the mist of the new global society?In this paper, we will take an evolutionary perspective of technology in architecture and draw parallelsbetween the Renaissance, which is the genesis of the modern architect, and the contemporary state ofarchitecture. The modern architect was birthed during the Renaissance where we see the retraction ofthe architect from the building site and separation from direct involvement in the building process.Communications technology (i.e. representation in the form of free-hand drawings, mechanical 2Dorthographic drawings and 3D perspectives) enabled the decomposition of the master builder into threecomponents (i.e. artist-designer, practicing_architect, and builder). Thus, we see technology enable thedenigration and ultimate dissolution of the centuries old craftsman guilds and the master builder. Thetechnology evolution of “drawings” enabled monumental change in the process of architecture over thepast five hundred years. The fission of the master builder, enabled by “drawings”, resulted in disparatefactions which are the forerunners of the modern day litigious design-bid-build project delivery. We nowincreasingly see a return to the fusion of design and building where often the architect is not the projectmanager or leader. Thus, the question looms, will the 21st century architect lead or be led, and whatare the ramifications for the profession?The historical Master Builder is re-emerging as a dynamically networked team of design andconstruction knowledge specialists. Bi-lateral knowledge exchange, enhanced with emerging IT, isoccurring between owners, managers, architects, design specialists, engineers, builders and machines.Technology is disrupting architecture, resulting in increasing specialization and compressed timeframes, and may require reevaluation of the role of the architect as project-leader "integrativegeneralist"or "design-specialist".Conclusively, the concept of ‘cybernetic architecture’ is proposed as an IT reference framework. Failureto appropriately respond to societal evolution, driven by technology, could result in the loss ofprofessional status for the modern architect. Herein lies our dilemma, or opportunity, depending on therole choice of the modern architect.

title Modulating Thermal Mass Behavior Through Surface Figuration
source ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 202-211
summary This research builds upon a previous body of work focused on the relationship between surface geometry and heat transfer coefficients in thermal mass passive systems. It argues for the design of passive systems with higher fidelity to multivariable space between performance and perception. Rooted in the combination of form and matter, the intention is to instrumentalize design principles for the choreography of thermal gradients between buildings and their environment from experiential, spatial and topological perspectives (Figure 1). Our work is built upon the premise that complex geometries can be used to improve both the aesthetic and thermodynamic performance of passive building systems (Cupkova and Azel 2015) by actuating thermal performance through geometric parameters primarily due to convection. Currently, the engineering-oriented approach to the design of thermal mass relies on averaged thermal calculations (Holman 2002), which do not adequately describe the nuanced differences that can be produced by complex three-dimensional geometries of passive thermal mass systems. Using a combination of computational fluid dynamic simulations with physically measured data, we investigate the relationship of heat transfer coefficients related to parameters of surface geometry. Our measured results suggest that we can deliberately and significantly delay heat absorption re-radiation purely by changing the geometric surface pattern over the same thermal mass. The goal of this work is to offer designers a more robust rule set for understanding approximate thermal lag behaviors of complex geometric systems, with a focus on the design of geometric properties rather than complex thermal calculations.

title Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source Delft University of Technology
summary The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.

summary In the paper-based world, CAAD-associations, such as ACADIA, and scientific publishers aim at gettingthe right people together and for making sure their work gets distributed to their peers. Electronicnetworks, such as the Internet, are providing scientists with the means to pursue those activities on theirown. In this paper we present the goals of an EU project called SciX. The goal of SciX is to analyze thebusiness processes of scientific publishing, to invent new publication models and through a series ofpilots to demonstrate how this should work. In the envisioned scenarios, professional associations suchas ACADIA play an important role. Their members are the potential users of SciX 's platforms, authorsand readers of the papers. Associations could also become the publishers and archivists of theknowledge created within their respective community. The objectives of this contribution focus oninvolving the ACADIA-community in the developments in SciX on fine-shaping the goals as well as ondefining the requirements and monitoring the usability of the pilots.

summary Computer-assisted reconstruction of no-longer existent (architectural) objects and their surroundingsamounts to a “virtual comeback”. Irreversible destruction having removed identity-establishing buildingsfrom the urban surface forever is the principal reason for re-creating them by imagination. Following thedestruction during the so-called “Reichskristall-Night” of November 1938, the synagogues of the Jewishcommunity in Vienna will only survive by means of virtual reconstruction. Sixty years later, in the commemorativeyear of 1998, the first synagogue reconstruction was initiated. The medium-range goal,however, aims at the reconstruction of at least ten additional synagogues as a project to be carried outin stages over a period of several years. Changes in personnel also call for a structure to be trackeddown later on. This paper deals with handling of modeling in a systematic manner, taking intoconsideration personnel changes,aiming at a traceable data structure for subsequent use and follow-upwork.

summary This research investigates the spatial information retrieval in architecture focused on constructingefficient metadata that is crucial for data retrieval. Generally speaking, metadata is ‘structured dataabout data’ to describe the resources especially in a digital method. In this research, metadata is a sortof data object to be used in searching spatial information, such as describing a raw spatial data objectnot only as attribute data but also as content, structurally and semantically. There are two issues thatmotivate this research; 1) the materialization of the intangible space as a data object, and 2) thecontent-based information retrieval. In the viewpoint of content-based retrieval, we analyze spatialinformation on the apartment unit floor plan common in Korea. Then we extract the metadata items in astructured manner. To manage the items efficiently, we develop a data model for spatial informationaccording to the concept of “Structured Floor Plan”. For exploiting the metadata, this research showsseveral possibilities of query operations to present a set of sample queries about L-D-K(Living room -Dining room – Kitchen). Implementation of the prototype system is divided into three parts: 1) amodeling module, Vitruvis; 2) an indexing module, SpaceCore; and 3) a browsing module.

title SpaceScope: Developing a Spatial Information Retrieval System - Focused on Apartment Unit Floor Plans -
source Yonsei University, Dept. of Housing & Interior Design
summary This research investigates the spatial information retrieval (IR) in architecture focused on constructing efficient metadata that is crucial for data retrieval. Generally speaking, metadata is ‘structured data about data’ to describe resources especially in a digital format. In this research, metadata is a sort of data object to be useful in searching spatial information. Metadata is also used to describe raw spatial data object as not only attribute data but also content structurally and semantic ally. There are two issues that motivate this research; 1) what is the spatial information – that materializes the intangible space as a data object, and 2) how we can search the information efficiently – the content-based information retrieval. Although knowledge of a building’s spatial content is most important in architecture, there has been no logical method to manage it.

From the viewpoint of content-based retrieval, the researcher analyzes spatial information of a floor plan, with a focus on the apartment unit floor plan common in Korea. Then the metadata items are extracted in a structured manner. To manage the items efficiently, the researcher develops a data model for spatial information according to the concept of the “Structured Floor Plan”. The main object of content to retrieve is a spatial network that consists of nodes of spaces and their linkages. There are two ways to organize the metadata: the traditional index files and the RDF (Resource Description Framework). While the index files are still efficient with computability, the RDF applies greater options to retrieve, such as fuzzy predicates, semantic predicates, and so on. To exploit the metadata, this research shows several possibilities of query operations that present a set of sample queries about L-DK(Living room – Dining room – Kitchen). Implementation of the prototype system is divided into three parts: 1) a modeling module using Vitruvius; 2) an indexing module using MS SQL Server? 2000 in conjunction XML; and 3) a browsing module using the SpaceScope browser.

The future works may consider XML-based databases and a knowledge based query language, such as RQL/XQL, working on such databases. The more specific domain knowledge is involved, the more practical systems would be. Even in architecture, there may be a diverse range of domain knowledge, such as design, building performance, facility management, energy management, post occupied evaluation, historical research, and so on. Also the issue of interface should be investigated in depth, so that it will be adequate to the needs of the architectural field.

source CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 151-158
summary Projects of ever increasing complexity and size have incited the need for new and robust design methodologies and tools in an effort to manage complexity, lower costs, ascertain quality and reduce risk. Technology convergence through the growing availability of networked computers, rapid progress in Computer Aided Design (CAD) and information management have encouraged the undertaking of even more complex designs that demand high degrees of interaction, collaboration and the efficient sharing and dissemination of information. It is suggested that interactive storytelling and interactive design (Rafi and Karboulonis, 2001) techniques that use non-linear information mapping systems can be deployed to assist users as they navigate information that is structured to address localized needs as they arise. The design process is a collaborative effort that encompasses diverse knowledge disciplines and demands the management and utilization of available resources to satisfy the needs of a single or set of goals. It is thought that building industry specialists should work close together in an organised manner to solve design problems as they emerge and find alternatives when designs fall short. The design process involves the processing of dynamic and complex information, that can be anything from the amount of soil required to level lands - to the needs of specific lightings systems in operation theatres. Other important factors that affect the design process are related to costs and deadlines. This paper will demonstrate some of our early findings in several experiments to establish nonlinear storytelling. It will conclude with a recommendation for a plausible design of such a system based on experimental work that is currently being conducted and is reaching its final stages. The paper will lay the foundations of a possible path to implementation based on the concept of multi-path animation that is appropriate for structuring the design process as used in the building industry.

title CAADRIA 2002 [Conference Proceedings]
source Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X / Cyberjaya (Malaysia) 18–20 April 2002, 370 p.
summary Evolution of trends in the realm of computer aided architectural design (CAAD) has seen the convergence of technologies – complementing traditional tools with emerging sciences like Information Technology (IT) and multimedia applications. This appliqué of technologies has not just expanded the scope and enhanced the realm of CAAD research and practice, but is also breaking new frontiers. This creative nexus will be realised at the 7th International Conference on Computer Aided Architectural Design Research In Asia (CAADRIA 2002) to be held at the Faculty of Creative Multimedia, Multimedia University, Malaysia, between 18th-20th April, 2002. CAADRIA 2002’s theme, "Redefining Content", seeks to recognise and infuse these emerging components in the field of architecture and design with a holistic approach towards online, digital and interactive systems. The 41 papers compiled were selected through a blind review process conducted by an international review panel. To reflect the multi-disciplinary nature of this year's conference, the chapters are arranged topically to facilitate the in-depth study of key components. The component sessions include: // Web Design, Database and Networks // CAD, Modelling and Tools // Collaborative Design, Creative Design and Case Reasoning // Simulation and Prototyping // Virtual Environment and Knowledge Management // Design Education, Teaching and Learning /// We believe that this specialised approach will provide a deeper and more illuminating feel of the various components and their critical convergence in the field of architecture and design.

title Design Decision Support through Translation between Multiple Representations of Spatial Data
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary Urban planning and urban design involve collaboration of diverse participants with multiple agendas and multiple criteria. The participants typically use multiple representations of spatial data to derive inferences and insights about the planning problems, leading to a shared decision-making process. To support such multidisciplinary work, this paper proposes a new computational approach and technique for translation between multiple representations of spatial data. This approach is designed to supportdesign decision-making in the interrelated interests of design participants. Prototype implementation and evaluation are conducted to test and validate the proposals.

title One City to Go: A Multi-modal Approach to Delivering City Data
source CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 057-64
summary The work described here is aimed at developing city models, with underlying data, in such a way that the model and data can be accessed quickly and efficiently. A particular outcome of our approach to the work is that the model and associated data can be accessed through a palmtop device. This degree of portability opens up a range of opportunities to access this important information; the kind of information related to city models and associated data that is expanding daily.

title Design phase transitions in object-oriented modeling of architecture
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 310-313
summary The project IDEA+ aims to develop an “Integrated Design Environment for Architecture”. Its goal is providing a tool for the designer-architect that can be of assistance in the early-design phases. It should provide the possibility to perform tests (like heat or cost calculations) and simple simulations in the different (early) design phases, without the need for a fully detailed design or remodeling in a different application. The test for daylighting is already in development (Geebelen, to be published). The conceptual foundation for this design environment has been laid out in a scheme in which different design phases and scales are defined, together with appropriate tests at the different levels (Neuckermans, 1992). It is a translation of the “designerly” way of thinking of the architect (Cross, 1982). This conceptual model has been translated into a “Core Object Model” (Hendricx, 2000), which defines a structured object model to describe the necessary building model. These developments form the theoretical basis for the implementation of IDEA+ (both the data structure & prototype software), which is currently in progress. The research project addresses some issues, which are at the forefront of the architect’s interest while designing with CAAD. These are treated from the point of view of a practicing architect.

title Exploring syntax and semantics of spatial structure - A study on Traditional Taiwanese City form in Chi’i’ng Dynasty
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 412-416
summary Abstract. In this paper, we want to figure out the relations of complex semantics and syntax on five traditional Taiwanese cities in Chi’i’ng Dynasty by using a language approach. The issues of traditional Taiwanese central city in Chi’ing Dynasty had been interpreting by historical, social, and cultural research but had lacked the explicit construction of spatial structure on semantics-syntax. Therefore, we use a data modeling on knowledge level to describe the relationship between syntax and semantics. Through the research of Chi’ing Dynasty‘s history, we find out the spatial relations of Taiwanese traditional city to establish the functional categories of spatial structures. Then the language of semantics components and the meaning’s attributes are coded as logical statements to map the elements of syntax on architectural form, political vocabularies, spatial layout, and spatial myth. We argue that using this approach several social and spatial structures of cities can be clearly defined and understood.
