title	A Multi-dimensional Exploration of Urban Attributes by Data Mining
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 333-350.
summary	The paper which is proposed here will introduce an ongoing research project aiming to research data mining as a methodology of knowledge discovery in urban feature analysis. To address the increasing multi-dimensional and relational complexity of urban environments requires a multidisciplinary approach to urban analysis. This research is an attempt to establish a link between knowledge discovery methodologies and automated urban feature analysis. Therefore, in the scope of this research we apply data mining methodologies for urban analysis. Data mining is defined as to extract important patterns and trends from raw data (Witten and Frank, 2005). When applied to discover relationships between urban attributes, data mining can constitute a methodology for the analysis of multi-dimensional relational complexity of urban environments (Gil, Montenegro, Beirao and Duarte, 2009) The theoretical motivation of the research is derived by the lack of explanatory urban knowledge which is an issue since 1970‚Äôs in the area of urban research. This situation is mostly associated with deductive methods of analysis. The analysis of urban system from the perspective of few interrelated factors, without considering the multi-dimensionality of the system in a deductive fashion was not been explanatory enough. (Jacobs, 1961, Lefebvre, 1970 Harvey, 1973) To address the multi-dimensional and relational complexity of urban environments requires the consideration of diverse spatial, social, economic, cultural, morphological, environmental, political etc. features of urban entities. The main claim is that, in urban analysis, there is a need to advance from traditional one dimensional (Marshall, 2004) description and classification of urban forms (e.g. Land-use maps, Density maps) to the consideration of the simultaneous multi-dimensionality of urban systems. For this purpose, this research proposes a methodology consisting of the application of data mining as a knowledge discovery method into a GIS based conceptual urban database built out of official real data of Beyoglu. Generally, the proposed methodology is a framework for representing and analyzing urban entities represented as objects with properties (attributes). It concerns the formulation of an urban entity‚Äôs database based on both available and non-available (constructed from available data) data, and then data mining of spatial and non-spatial attributes of the urban entities. Location or position is the primary reference basis for the data that is describing urban entities. Urban entities are; building floors, buildings, building blocks, streets, geographically defined districts and neighborhoods etc. Urban attributes are district properties of locations (such as land-use, land value, slope, view and so forth) that change from one location to another. Every basic urban entity is unique in terms of its attributes. All the available qualitative and quantitative attributes that is relavant (in the mind of the analyst) and appropriate for encoding, can be coded inside the computer representation of the basic urban entity. Our methodology is applied by using the real and official, the most complex, complete and up-to-dataset of Beyoglu (a historical neighborhood of Istanbul) that is provided by the Istanbul Metropolitan Municipality (IBB). Basically, in our research, data mining in the context of urban data is introduced as a computer based, data-driven, context-specific approach for supporting analysis of urban systems without relying on any existing theories. Data mining in the context of urban data; ‚Ä¢ Can help in the design process by providing site-specific insight through deeper understanding of urban data. ‚Ä¢ Can produce results that can assist architects and urban planners at design, policy and strategy levels. ‚Ä¢ Can constitute a robust scientific base for rule definition in urban simulation applications such as urban growth prediction systems, land-use simulation models etc. In the paper, firstly we will present the framework of our research with an emphasis on its theoretical background. Afterwards we will introduce our methodology in detail and finally we will present some of important results of data mining analysis processed in Rapid Miner open-source software. Specifically, our research define a general framework for knowledge discovery in urban feature analysis and enable the usage of GIS and data mining as complementary applications in urban feature analysis.

title	Analyzing Pedestrian Movement in Mataf Using GPSand GIS to Support Space Redesign
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	Evaluating the use of architectural and urban spaces is an important issue for architects and urban designers who wish to enhance space usability. Space usability is crucial in crowded spaces such as Mataf areas. Millions of people come to the city of Makkah, Saudi Arabia every year to perform Hajj (Islamic Pilgrimage) and Umrah. A cornerstone of Hajj and Umrah spirituals is to perform Tawaf, which is the circumambulation of the Ka'bah in the center of the Holy Mosque in Makkah. The areas of performing Tawaf (called Mataf) become very crowded during Hajj and the last ten days of Ramadan. This paper demonstrates how we utilized Global Positioning Systems (GPS) and Geographic Information Systems (GIS) to analyze pedestrian movement while performing Tawaf. During the Hajj of 1424 H (2004 in the Georgian Calendar), several GPS devices were used to collect pedestrian movement coordinates at specific time intervals. Computer software for tracking analysis is used to visualize and analyze the pattern of pedestrian movement in Tawaf. The software allows users to view temporal data, which can be set up with past time windows for historical data analysis. The findings of this research show levels of service and flow rates throughout different zones and times of Mataf. They indicate the most critical zones and times for Tawaf during Hajj. They also visually demonstrate the track pattern of pedestrian movement at different locations in the Tawaf area. The paper concludes with some redesign recommendations to remove obstacles and facilitate pedestrian movement in Tawaf. The approach described in this paper can be implemented in architectural and urban design space modifications to improve pedestrian movement in open spaces.

summary	By inter-relating CAD and satellite image earth-viewing tools at building specific, city-wide and larger global scales, a wider framework of observation yields insight into the connectedness between built environments and tracking influences between them. The technologies for visualization and analysis at distinct scales are moving towards greater integration. This project demonstrates integration through three case studies, each at a different scale of application, and considers performance issues and implications for more general use. More specifically, CAD, GIS and now Satellite Image Based Earth Viewing systems all have found separate application within Architecture, Urban Planning and Strategic Regional Analysis This paper reports on an effort to test the tighter coupling of these systems on three projects, each at a different scale: (1) urban and regional scale, (2) continental scale, and (3) hemispheric analysis scale.

title	Visualization of Usable Building Space According to Planning Permission Ordinances for Public Participation in District Plan in Japan
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & DecisionSupport Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-2408-8, p. 85-98
summary	The district plan in Japan is designed and implemented through public participation, which is based on the zone restrictions of land use system. The usable space of a building can be generated according to the zone restrictions implemented in a district plan, which include the planning controls of high altitude, oblique line and so on. Residents can choose control items as their preference in order to control the urban physical environment of the district. In this paper, we discuss how to generate the virtual world according to the data set of GIS including planning control items and how it can work for net participation. In the future, we would like to conduct an Internet social experiment with the cooperation of a city government and residents in order to support the district plan in a local city.

title	Using Bayesian Decision Networks for Knowledge Representation under Conditions of Uncertainty in Multi-Agent Land Use Simulation Models
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN 1-4020-24088, p. 129-144
summary	Land suitability analysis typically involves the assessment of the suitability of land units without knowing the future spatial distribution of land use. Traditional planning techniques have used “algebraic equations” to express land suitability as a weighted function of suitability scores across multiple criteria. However, the existing multi-criteria evaluation methods do not systematically account for uncertainty about the land use in adjacent and other cells. This paper proposes an alternative approach to land suitability analysis that does address the problem of uncertainty. In particular, Bayesian decision networks are suggested as a means of knowledge representation for agents in a multi-agent land use simulation system. Bayesian decision networks model the uncertainty in terms of probabilities specified in the network representing the expertise of specialists with respect to specific land uses. This paper discusses the approach and illustrates its use in the context of a retail agent.

title	Sistema de representação gráfica para estudo de localização de atividades ligadas ao ciclo de produção do biodiesel no nordeste brasileiro [Graphic Representation System for a Localization Study on Activities Related to the Production Cycle of Biodiesel in the Brazilian Northeast]
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	This paper presents the development of graphics interface on GIS (Georeferenced Information System) applied to a location model. The model performs an hierarchical analysis to locate activities related to the Biodiesel production cycle, based on castor oil (Ricinus communis L.). The case study is placed in Brazilian Northeast region, and indicates properly selected counties for Biodiesel major stages: planting, crushing and oil processing. The GIS was implemented on Windows with Personal Geodatabase and Feature Class, applied to SAD 69 references, and involves a large set of administrative, economical, social, environmental and agricultural data. Both partial and final results were obtained with graphical and query methods for selecting and editing data. A fuzzy set program imports territorial offer data and exports location indicators to database. Thematic maps are used for hierarchical data organisation and to perform a Biodiesel stages zone classification, based on graphical analysis of generated data.

title	Exploración de relaciones entre analogías y bocetos durante la generación de ideas en diseño industrial como elicitación de requerimientos para CAD [Exploration of Relations between Analogies and Sketches During the Generation of Ideas in Industrial Design for Eliciting CAD Requirements]
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	An exploration on the analogy-based idea generation process in industrial design is reported. In particular we try to identify relationships between the sketching process and the analogy building in order to elicit requirements for a supporting software. We use concurrent think aloud protocols to obtain experimental data and an extension of a proved content oriented schema to analyze them. Statistical analysis on segments containing .analogical chains. found relations between analogical and design actions that allow us to support the hypothesis that the sketch seems to be more useful for helping the analytical aspects of the analogical making (i.e. to code a situation in terms of higher order relations) than the synthetic ones (i.e. to identify an analogy source). Results were interpreted as software requirements for a Computer Aided Design Application.

title	Towards a Multi Agent System for the Support of Collaborative Design

summary	In this paper we are drafting the outline of a framework for a Multi Agent System (MAS) for the support of Collaborative Design in the architectural domain. The system we are proposing makes use of Machine Learning (ML) techniques to infer personalized knowledge from observing a users’ action in a generic working environment using standard tools such as CAD packages. We introduce and discuss possible strategies to combine Concept Modelling (CM)-based approaches using existing ontologies with statistical analysis of action sequences within a domain specific application. In a later step, Agent technologies will be used to gather additional related information from external resources such as examples of similar problems on the users hard disk, from corresponding work of team-members within an intranet or from advises of expert from different knowledge domains, themselves represented by agents. As users deny or reward resulting proposals offered by the agent(s) through an interface the system will be enhanced over time using methods like Reinforced Learning.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

title	Improved Understanding of Urban Sprawl Using Neural Networks
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 14020-2408-8, p. 33-49
summary	It is widely accepted that the spatial pattern of settlements is a crucial factor affecting quality of life and environmental sustainability, but few recent studies have attempted to examine the phenomenon of sprawl by modelling the process rather than adopting a descriptive approach. The issue was partly addressed by models of land use and transportation which were mainly developed in the UK and US in the 1970s and 1980s, but the major advances were made in the area of modelling transportation, while very little was achieved in the area of spatial and temporal land use. Models of land use and transportation are well-established tools, based on explicit, exogenouslyformulated rules within a theoretical framework. The new approaches of artificial intelligence, and in particular, systems involving parallel processing, (Neural Networks, Cellular Automata and Multi-Agent Systems) defined by the expression “Neurocomputing”, allow problems to be approached in the reverse, bottom-up, direction by discovering rules, relationships and scenarios from a database. In this article we examine the hypothesis that territorial micro-transformations occur according to a local logic, i.e. according to use, accessibility, the presence of services and conditions of centrality, periphericity or isolation of each territorial “cell” relative to its surroundings. The prediction capabilities of different architectures of supervised Neural networks are implemented to the south Metropolitan area of Milan at two different temporal thresholds and discussed. Starting from data on land use in 1980 and 1994 and by subdividing the area into square cells on an orthogonal grid, the model produces a spatial and functional map of urbanisation in 2008. An implementation of the SOM (Self Organizing Map) processing to the Data Base allows the typologies of transformation to be identified, i.e. the classes of area which are transformed in the same way and which give rise to territorial morphologies; this is an interesting by-product of the approach.

summary	In order to contribute to the elaboration of more expressive architectural animations, some famous films, documentaries of buildings and award-winning animations were analyzed. This was carried out examining the cinematographic techniques used at three levels of filming language; image setting, shot movements and montage, according to concepts described in theoretical texts. The analysis revealed an extensive use of techniques, in particular in movies, that give graphic diversity and perceptual stability. Based on that, it proposes some ideas for the planning of an architectural animation and a computer implementation of some filmic concepts, in particular related to movements of the point-of-view. This study suggest a fragmented view of building designs, to get an appealing moving presentation, with visual interest and continuity, as such should be also in architecture.

title	What Is Intention Structure? - Represent Invisible Information of Spatial Depicts
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 275-286
doi	https://doi.org/10.52842/conf.caadria.2004.275
summary	The significant problem of this paper is how we convey spatial information to represent concrete meaning of mental imagery. For replying the above problem, we are developing a spatial information structure called "Intention Structure". Intention structure is used to represent some spatial experience of a particular person and awareness of the aura into some spatial depicts at that physical place. The meaning of “intention” is implied into a sequential relation when a navigator moves and gazes something in a place. This sequential relation can be described into two ways of spatial representation: one is the action of human body including “moving the body” and “moving the head”; another is converting the visual information into spatial memories through the behavior of gaze, including “the sight focus” and “the snapshot glance”. Otherwise, we also consider the limitation of topology at that physical place. Based on the above ideas, we use XML technologies in Java language to represent spatial data of intention structure for the describable usages of invisible information. we implemented this idea on a project of spatial analysis with Taiwanese traditional garden, the Lin family garden in Banciao, Taipei County, Taiwan.

title	Between Mediation and Making CIMSp: A Technoètic Modus Operandi
source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 435-442
doi	https://doi.org/10.52842/conf.ecaade.2004.435
summary	The following paper describes an ongoing research project whose goal is to define a scalable, hybrid production and deployment protocol (CIMSp) for the creation of virtual environments (VE). Ultimately, the aim is to establish a creative workflow and infrastructure that embodies architectural and urban design activity as practiced by the research unit. The objective of the present paper is to schematically outline the current state of the research and its practical and theoretical context for further development. A theoretical position will be stated which assumes that the content, tool, epistemological, and speculative realms are consubstantial (technoèsis). The practical endeavour is to create the informational and embodied temporal--spatial condition of possibility for the imaginative production of cultural artifacts. It must accommodate varying individual and collaborative forms and styles of making and no presumption of a self-enclosed and referential system is made. A critical position is particularly compelling when this production is immersed in technological modalities of making where information and embodiment are inextricably intertwined. CIMSp is based on the workflow from acquisition and creation to output and storage. The work environment is comprised of a select set of software applications and visualization technologies. Secondly, an XML-based content and information management system is under construction to ensure project quality control, rigorous documentation practices, and bi-directional knowledge feedback procedures to enable an effective and resource-full workflow. Lastly, scalability of output modalities for use in the design process and for final presentation from WWW deployment to a high-resolution collaborative work environment (CWE) is being developed. The protocol is a multiuser mode of creation and production that aims to transform the technologies and their interrelation, thus dramatically impacting the creative process and intended content. It is a digital production workflow that embodies intensive visualization criteria demanded by the end users. The theoretical and practical intention of CIMSp is to provisionally structure the collaborative creative process and enable a choreographed movement between the realms of the technologically mediated and made in the pursuit of significant digital content creation.

title	Space is the Machine, with a Ghost Inside
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 157-173
summary	The purpose of this paper is to report efforts towards the construction of a model for urban spatial dynamics simulation, based on multi-agents and space. The underlying idea is to have urban space producers and consumers operating in a two-layer, two-circuit model. The first layer holds urban space and its successive transformations; a second layer contains agents related to space; the first circuit simulates space production, and a second one simulates space consumption. Relationship between layers is represented as objective spatial features that agents are submitted to (the machine) and subjective meanings agents attach to each spatial feature (the ghost). While space works always in the same way, meanings vary according to each agent’s background and context. Relationships between circuits are represented by means of a market game in which producers try to maximize their profits by gambling with their risks, whereas consumers try to foresee the spatial distribution of local externalities that maximizes their utilities and investments. Urban Spatial Features are captured through centrality and land use patterns; every single agent’s action leads to changes in both patterns. Producers’ profit is a function of built form location. Consumers’ local externalities are concerned basically with present and future services. The model iteration is twofold: first it generates and allocates a number of built forms within a previously determined spatial system (a cellular matrix, for example), and second it allocates users to built forms. Population of users have its social profile and growth rate externally determined. Built form allocation is decided on the basis of a combination of profitXrisk perspectives. Users’ locational choice is supported by accessibility to services and present/future neighbourhood profile. Built form allocation works as parameter for users’ locational assessment, whereas users’ choices are used as parameters for developers. The model tends to adjust itself, in terms of quantities and types of built forms to be erected, although through a market lag of some iterations. Allocations are always made through weighted draws, so that mutations (non deterministic allocations) do occur.

title	Dynamic Linkages between Ideas and Cases

summary	This research makes use of a cognitive study to explore a mechanism for associating ideas in a brainstorming session. Firstly, we propose a linking model integrating three principles of idea association (similarity, contrast and contiguity) with two processes of case-based reasoning (retrieval and adaptation). For identifying the types and mechanisms of linkages within the linking model, a design experiment and its protocol analysis was conducted. Finally, a framework for case-based reasoning to support idea association called Dynamic Idea-Maps (DIM) is proposed, and its components and mechanisms are elucidated.

title	Identification and Visualisation of Construction Activities’ Workspace Conflicts Utilising 4D CAD/VR Tools
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	This work addresses the problem arising on all construction sites: the occurrence of workspace interference between construction activities. From a site space planning context, this problem can lead to an inevitable roadblock to the progress of the scheduled construction operations. In real situations, when the spatial congestions occur, they could reduce productivity of workers sharing the same workspace and may cause health and safety hazard issues. The aim of this paper is on presenting a computer-based method and developed tool to assist site managers in the assignment and identification of workspace conflicts. The author focuses on the concept of ‘visualising space competition’ between the construction activities. The concept is based on a unique representation of the dynamic behaviour of activity workspace in 3D space and time. An innovative computer-based tool dubbed PECASO (Patterns Execution and Critical Analysis of Site-space Organisation) has been developed. The emerging technique of 4D (3D + time) visualisation has been chosen to yield an interesting 4D space planning and visualisation tool. A multi-criteria function for measuring the severity of the workspace congestions is designed, embedding the spatial and schedule related criteria. The paper evaluates the PECASO approach in order to minimise the workspace congestions, using a real case study. The paper concludes that the PECASO approach reduces the number of competing workspaces and the conflicting volumes between occupied workspace, which in turn produces better assessment to the execution strategy for a given project schedule. The system proves to be a promising tool for 4D space planning; in that it introduces a new way of communicating the programme of work.

title	Asymptote: Flux
source	International Journal of Architectural Computing vol. 2 - no. 2
summary	Flux’s value is the combination of rich visual imagery organized around thechronological projects of Asymptote with insightful interviews that revealthe process of design that blurs the distinction of physical architecture andcyberspace. Asymptote actively experiments with the contemporarymeaning of space while embracing physical and virtual notions of experienceand meaning within a hybrid model. The descriptions of the projects revealan evocative insight to process and meaning but lack critical, or alternative,points of view. However, this does not diminish the overall use of Flux inrevealing the importance of a critically based understanding of digitaltechnology, cyberspace, and new directions in architecture.

title	Modelagem geométrica como instrumento de análise e representação de mobiliário [Geometric Modeling as Instrument for Furniture Analysis and Representation]
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	This work explores the Geometric Modeling possibilities as a tool for professional use to the Furniture Design by Interior Architecture professionals. It is considered that the modeling process contributes to the characterization of furniture, since it is necessary the definition of the geometric procedures to generate and control the represented form. Searching for evidences of the kind of contribution, some experiments were developed using chairs from different periods as the object for representation. Three chairs were selected to model, from three different historical periods. The modeling processes were based on the use of 3D Studio Max, registered, analyzed and compared. The results defined references to the use of Digital Graphics to support the representation and also to studies of the furniture form.
