title	From Intuition to Precision

summary	Design has been described as making inspire decisions with incomplete information. True, we may use prior knowledge, we may even think we understand the causalites involved, but what really matters is exploration: of new forms, of new materials, and speculation about the response to the resulting effects. Essentially, this exploration has its own dynamics, involving intuition and spontaneity, and without which there is no design. But of course we all know that this is not the whole story. Design is different to 'craft'; to directly 'making' or 'doing'. It necessarily has to be predictive in order to anticipate what the consequence of the 'making' or 'doing' will be. Therefore we inevitably have to counter balance our intuition with a well developed sense of premeditation. We have to be able to reason about future events, about the consequence of something that has not yet being made. There is always going to be an advantage if this reasoning can be achieved with a degree of precision. So how can we progress from intuition to precision? What abstractions can we use to represent, externalize and test the concepts involved? How can we augment the cognitive processes? How can we record the progression of ideas? And, how do we know when we have arrived? Design has a symbiotic relationship with geometry. There are many design issues that are independent of any specific configurations. We might call these “pre-geometric” issues. And having arrived at a particular configuration, there may be many material interpretations of the same geometry. We might call these “post-geometric” issues. But geometry is central to design, and without appropriate geometric understanding, the resulting design will be limited. Geometry has two distinct components, one is a formal descriptive system and the other is a process of subjective evaluation.

summary	Throughout history, architecture has transposed contributions bound to structuralist focus or to musical composition. This is from linguistic and music respectively. New visualization systems show the possibility to give transpositions a new meaning, form the potentialities of hypermedia; locking for new projects parameters. This papers will show experimental workshop results developed within CI+D 2000 “New speeches and design process”. They study links and explore our work interrelating word – music and image. These processes are developed by people coming from literature, visual arts, music, and architecture areas. Lastly, the first results will be shown. Since parameters were transposed from music, by using NURBS forms, space prefiguration is tried out. [Full paper in Spanish]

summary	The research paper exemplifies a novel information integrated design technique developed at ONL (Oosterhuis and Lenard), Netherlands, specifically appropriated for envisaging complex geometric forms. The ‘informed design technique’, apart from being highly instrumental in conceptualizing and generating the geometric component constituting architectural form in a parametric manner, is also efficiently utilized for precise computer aided manufacturing and construction of the speculated form. Geometric complexities inherent in contemporary architectural constructs and the time spent in appropriation of such topologies, fueled the ‘informed design’ approach, which caters to issues of timely construction, precision oriented design and production (visual and material) and parametric modeling attuned to budgetary fluctuations. This design-research approach has been tested and deployed by ONL, for conceiving ‘the Acoustic Barrier’ project, Utrecht Leidsche Rijn in the Netherlands and is treated as a generic case for exemplifying the ‘informed design’ technique in this research paper. The design methodology encourages visualizing architectural substantiations from a systems perspective and envisages upon a rule based adaptive systems approach involving extrapolation of contextual dynamics/ground data in terms of logical ‘rules’. These rules/conditionalities form the basis for spawning parametric logistics to be mapped upon geometric counterparts exemplifying the conception. The simulated parametric relations bind dimensional aspects (length, width, height etc.) of the geometric construct in a relational manner, eventually culminating in a 3D spatial envelope. This evolved envelope is subsequently intersected with a ‘parametric spatio-constructive grid’, creating specific intersecting points between the two. The hence extorted ‘point cloud’ configuration serves as a generic information field concerning highly specific coordinates, parameters and values for each individual point/constructive node it embodies. The relations between these points are directly linked with precise displacements of structural profiles and related scaling factors of cladding materials. Parallel to this object oriented modeling approach, a detailed database (soft/information component) is also maintained to administer the relations between the obtained points. To be able to derive constructible structural and cladding components from the point cloud configuration customized Scripts (combination of Lisp and Max scripts) process the point cloud database. The programmed script-routines, iteratively run calculations to generate steel-wireframes, steel lattice-structure and cladding panels along with their dimensions and execution drawing data. Optimization-routines are also programmed to make rectifications and small adjustments in the calculated data. This precise information is further communicated with CNC milling machines to manifest complex sectional profiles formulating the construct hence enabling timely and effective construction of the conceptualized form.

title	Fabricating Ceramic Covers
doi	https://doi.org/10.52842/conf.ecaade.2005.269
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 269-276
summary	This paper describes a studio experiment developed with the aim of exploring the design and fabrication of innovative roof systems based on ceramic tiles using digital technologies. History is rich in examples of the use of ceramic roof tiles since the ancient world. Today’s systems derive from such ancient systems and fall into several basic categories depending on the form of the tiles and how they interlock. These systems present acceptable functional performances due to centuries of refinement, but as they have suffered little formal evolution in recent centuries, to respond to modern needs they require complex layering and assemblies. Recent technological evolution has emphasized the optimization of the tile production process in terms of time saving and cost reduction, and the improvement of product quality in terms of material homogeneity and durability. Little attention has been paid to the tile form and the roof system as a whole, including the assembly process. As a result, despite the variety and performance of existing designs, they are often perceived as outdated by architects who refuse to use them following a stylistic trend in architectural design towards primary forms and flat roofs. The challenge of the experiment was to take advantage of digital design and fabrication technology to conceive systems with improved performance and contemporary designs. The hope was that this could lead architects to consider integrating roof tiles systems in their architectural proposals. Results yielded five different roof systems. These systems are innovative from a formal viewpoint both at the tile and roof level. In addition, they are easy to assemble and possess better thermal and water-proofing performance. Digital technologies were determinant to enable students to design the complex shape of the tiles, to manipulate them into assemblies, and to assess the shape of the roofs, as well as their thermal and structural performance in some cases.

source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 778-782
summary	The search by new architectural forms with digital media loses interest when its results become foreseeable and repetitive in the growth of the large cities. At present, the interest is greater by the processing and manipulation of digital databases as alternatives of the architectural project. The resultant architectures possess forms that contrast less but with greater diversity in their spatial relations. DATABASE 3D is presented like a formal proposal risked of investigation. The experiences of project explore the concepts of Collective Autor, digital database and Hipertexto. It accepts the construction of a diverse and complex reality conformed by fragmentary spatial systems from the adoption of the mosaic, collage, remix and the digital sampling. [Full paper in Spanish]

title	Creative Design Between Representation and Simulation

summary	Milestone figures of architecture all have their different views on what comes first, form or function. They also vary in their definitions of creativity. Apparently, creativity is very strongly related to ideas and how they can be generated. It is also correlated with the process of thinking and developing. Creative products, whether architectural or otherwise, and whether tangible or intangible, are originated from ‘good ideas’ (Elnokaly, Elseragy and Alsaadani, 2008). On one hand, not any idea, or any good idea, can be considered creative but, on the other hand, any creative result can be traced back to a good idea that initiated it in the beginning (Goldschmit and Tatsa, 2005). Creativity in literature, music and other forms of art is immeasurable and unbounded by constraints of physical reality. Musicians, painters and sculptors do not create within tight restrictions. They create what becomes their own mind’s intellectual property, and viewers or listeners are free to interpret these creations from whichever angle they choose. However, this is not the case with architects, whose creations and creative products are always bound with different physical constraints that may be related to the building location, social and cultural values related to the context, environmental performance and energy efficiency, and many more (Elnokaly, Elseragy and Alsaadani, 2008). Remarkably, over the last three decades computers have dominated in almost all areas of design, taking over the burden of repetitive tasks so that the designers and students can focus on the act of creation. Computer aided design has been used for a long time as a tool of drafting, however in this last decade this tool of representation is being replaced by simulation in different areas such as simulation of form, function and environment. Thus, the crafting of objects is moving towards the generation of forms and integrated systems through designer-authored computational processes. The emergence and adoption of computational technologies has significantly changed design and design education beyond the replacement of drawing boards with computers or pens and paper with computer-aided design (CAD) computer-aided engineering (CAE) applications. This paper highlights the influence of the evolving transformation from Computer Aided Design (CAD) to Computational Design (CD) and how this presents a profound shift in creative design thinking and education. Computational-based design and simulation represent new tools that encourage designers and artists to continue progression of novel modes of design thinking and creativity for the 21st century designers. Today computational design calls for new ideas that will transcend conventional boundaries and support creative insights through design and into design. However, it is still believed that in architecture education one should not replace the design process and creative thinking at early stages by software tools that shape both process and final product which may become a limitation for creative designs to adapt to the decisions and metaphors chosen by the simulation tool. This paper explores the development of Computer Aided Design (CAD) to Computational Design (CD) Tools and their impact on contemporary design education and creative design.

summary	The subject of this digital art project is the process of erosion-sedimentation in general, and the leaching (process of separation of a contained soluble substance in an insoluble compound) in individual. In the name of the project one includes the light, since it is possible to ask themselves if there is a luminance erosion-sedimentation-leaching, or to try to establish an analogy between the natural leaching of the ground and the luminance radiations. Lúxive tries to generate a dialectic one with the process reality of the natural phenomenon, an atmosphere based on the time: it demands the apprehension of his temporary reality to be able to translate it from the imaginative activity. Lúxive does not try to imitate the erosion of the light, but to take elements from his to occur for reconstruct itself in forms to see and listen, from elements that conform the atmosphere in tacit form.

title	The Tower of Babel: Bridging Diverse Languages with Information Technologies
doi	https://doi.org/10.52842/conf.acadia.2005.184
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 184-191
summary	New digital tools or information technologies are providing the means for architects to realize unprecedented architectural creations. Unfortunately, the promise these technologies hold is far from their potential expression in the built physical environment. A contributing cause to this disjunctive state is the multiplicity of languages and knowledge sets employed by the various team members or actors engaged in a building project. From the cost models of the owners to the shop drawings of the fabricators, each actor views the project in terms specific to their individual discipline. In order to successfully engage the building process, these new technologies must account for this condition and develop means in which to span across traditional boundaries. This paper will examine the disjointed and fractured nature of the building project and identify opportunities for the deployment of information technologies to bridge boundaries, ultimately providing for and delivering architectural projects of unparalleled precedence. Specific aspects inherent to these technologies will be examined to understand where their application may benefit the building process. The key attributes this paper will focus on include: visualization tools, centralized database, cross discipline platform tools and novel forms of information representation. A case study of an architectural project will serve as the means in which to study the successful implementation of these attributes and their resulting impact on the design process and building project. This study will demonstrate how information technologies can be implemented within the multifaceted framework of conventional building projects to yield a project of unprecedented form.

title	Generation of Apparently Irregular Truss Structures
source	Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 229-238
summary	While cheaper mass-customisation technologies are becoming available, architectural design strives for ever more complex and less regular forms. The increasing costs associated with this tendency are difficult to control. Key factors contributing to this cost increase are non-uniform building components. Focusing on space frame construction, this paper examines the possibility of creating apparently irregular structures from relatively small sets of identical parts. Starting with an examination of the cost implications of irregular truss construction, a case study of the Beijing National Swim Center's space frame system and the conflicting natures of bottom-up and top-down generative logic in this context is presented. The paper concludes with the description of the development of a truss system that incorporates various design variables that increase visual irregularity. Learning from the past, this new system draws its basic logic from classic space frame principles but applies present-day computational logic to achieve new aesthetic effects and structural possibilities.

title	Designing Continuous ComplexCurved Structures to be Fabricated from Standard Flat Sheets
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 114-119
summary	This paper explains how complex curved structures can be constructed from flat standard panels. The main objective is to link both design techniques and digital fabrication methods to solve a recurrent problem in contemporary architectural design, building double curved structures. Secondly, it achieves this by using regular fabrication methods and standard construction materials, available and affordable for Latin-American countries. It describes the processes of programming a set of computational tools to study and develop designs to fabricate continuous complex curved structures. I will describe this through a series of experiments, using parametric design environments and scripted routines for CAD software to implement certain techniques to fabricate these designs using rapid prototyping machines. I compare different fabrication methods using computer numerically controlled machines, used to process these flat panels to obtain certain properties, allowing them to bend, twist, fold or stretch achieving these complex forms.

title	Using multimedia to link experts' views and derive common conclusions
source	Automation in Construction 6 (1) (1997) pp. 3-9
summary	Few publications on technology are read from start to finish and, where a broad subject is covered, only part of the content is relevant to a particular reader. Facilities such as multimedia and hypertext allow documents from different sources and containing various forms of data to be linked into a report which can be published electronically. Those who access a report, such as Building IT 2005, can then go direct to the topics of particular interest, visit related topics and background data, or search the text for particular terms. The most appropriate medium can be used whether text, data, images or video, and useful material extracted for teaching or research. Actions can be linked back to the papers in which they were recommended so that, while conclusions are presented compactly, the full context and the credentials of the author can be seen.

title	A Preliminary Model of Creativity in Digital Development of Architecture

summary	Research into the various forms and processes of creativity has been a topic of great interest in the design field for many years. Part of the view is personality, and part of the answer is behavioural. Creativity is also explained through the identity of social values and the whole creative process. This paper proposes to use the interacting creativity model of Csikszentmihalyi as the basic structure, to establish the major criteria of testing creativity in the digital era. This paper demonstrates two facts: first, it confirms that creativity in architecture is truly valuable in the digital age; second, it proves that in the digital era, individuals, cultures and societies are all under the impact of digital technologies, a fact which transforms the model of interacting creativity proposed by Csikszentmihalyi in 1988 into a new model of digital interacting creativity.

title	Poiesis and Autopoiesis in Architecture
doi	https://doi.org/10.52842/conf.acadia.2005.048
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 48-57
summary	The use of digital technology in architecture has proven to be more assertive than originally thought: it has reconditioned the nature of the design process, and established new processes and techniques of fabrication. Recent applications in digital technology show inquisitiveness in the contentious subject Genetic Algorithms. This new architectural process is characterized by two main shifts: from poiesis (or poetry) to autopoiesis, and from authenticity to mimesis. Since evolutionary simulations give rise to new forms rather than design them, architects should now be both artists and operators of both Inventive and Systematic design. Inventive design: The digital media should bring about poiesis (poetry). Digital spaces reveal and visualize the unconscious desires of urban spaces, bringing forth new dreamscapes, mysterious and surreal. This implies a Freudian spatial unconscious, which can be subjected to analysis and interpretation. The tools of digital dreaming, meanwhile, have opened a window to the ‘urban unconscious’. Systematic Design: Digital media should bring about an autopoiesis. This approach calls into question traditional methods of architectural design that replace the hierarchical processes of production known as “cause and effect,” and propose a design process where the architect becomes a constructor of formal systems. Will the evolutionary simulation replace design? Is metric space dead? The new algorithmic evolutionary conditions give architecture an autopoiesis, similar to biological dynamics. Paradoxically, the new emerging process is more insightful. The emphasis of the exploration is on morphological complexity. Architecture, through “machine” fabrication, may become more responsive, rigorous and poetic.

title	Talking Dirty: Formal and Informal Communication in Construction Projects
source	Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 265-274
summary	We analyse the emergence and use of formal and informal communication tools in group working to aid in understanding the complexity of construction projects. Our test case is the design and build of an interactive digital installation in an exhibition space, involving students. After the project we conducted focus group studies to elicit insights into the effective use of the digital communications available for the project. We recount key insights from the study and examine how digital messaging devices are contributing to or hindering creative discussion. Whereas the construction process is concerned with the removal of dirt and re-ordering, in this paper we reflect on construction’s ritualistic, contractual and unauthorized aspects, and dirt’s role within them. We draw on Bakhtin’s theories of the carnival in exploring ritual, and the mixing of the un-sanctioned (rumour) with the official (contractual). How does dirt impinge on issues of communication, open discussion, and the move towards “partnering” in construction practice? We conjecture that while physical dirt might be unpleasant, the removal of other forms of metaphorical dirt hampers construction as an efficient and creative process.

title	The Nazca Lines and their Digital Architectural Representation

source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	This paper relates to a digital architectural design experience in 2005 for the Nazca Competition. Nazca is an archaeological site situated about 400 kilometers south of Lima, Peru. It is a large desert with gigantic millenary geoglyphs carved on the surface, which can only be seen clearly from above. The Nazca geoglyphs are made up of hundreds of lines, spirals and triangular plazas, as well as zoomorphic figures like birds, fish, spider, etc. The Nazca Competition asked for an observatory-lodge of approximately 1.000m2 with 20 rooms, communal bathrooms, supporting areas and an observatory tower of at least 100 meters. The observatory-lodge was designed using a digital representation technique called "Genetically Constructed Structures". The structure was created using the geometric principle of the affinity of two conic sections: circle and ellipse. The form was produced transforming the circle and the ellipse by performing basic geometric transformations (translation, rotation, reflection and scaling). According to this technique, the sequence of transformations was codified in the form of an alphanumerical string, metaphorically named the "DNA structure". The code was inserted as extended data into the entities which shaped the structure profiles. The algorithms were programmed with AutoLISP language. The "DNA code" allowed the structure to be constructed and deconstructed from any point, generating many different forms, to be studied and compared. One year later, the same 3D model was used to test another digital technology called "musical box" where their geometrical points are captured, read and translated into musical parameters, generating music. In this paper we will present the graphical form of the tower as well as the music associated.

source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 75-79
summary	Contemporaneus art constructs its own space: interactive, multiple, eidetic, heterogenous, discontinuous and subjective: essence, forms and idea of a heterotopic at the same time atopic space, that arises at the moment of the intelligible apprehension of the work. This work sets out to study the construction codes of that space from the spectator point of view, for whom the history is the sum of histories narrated by the space, the scenery, stage scene, choreography, dances, hairdos, accessories, make-up, clothes, illumination, music, sounds, songs, word, performance, gestures etc., for which sets out the analysis from the perceived, analyzed and interpreted images by the spectator. It will be exemplified from the Dogville film, of Lars Von Traer (2004), using the qualitative research method, where the speaker meaning is introduced: the creator intentionality of those spaces, but is inescapable who arises the “interpretation” from the observer.

title	Sensitive Voxel - A reactive tangible surface
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. 525-538.
summary	Haptic and tactile sensations, the active or passive exploration of our built surroundings through our sense of touch, give us a direct feeling and detailed information of space, a sense of architecture (Pallasmaa 2005). This paper presents the prototype of a reactive surface system, which focuses its output on the sense of touch. It explains how touch sensations influence the perception of architecture and discusses potential applications that might arise from such systems in the future. A growing number of projects demonstrate the strong impact of interaction design on the human senses and perception. They offer new ways of sensing and experiencing architectural space. But the majority of these interaction concepts focus on visual and auditory output-effects. The sense of touch is typically used as an input generator, but neglected as as a potential receiver of stimuli. With all the possibilities of sensors and micro-devices available nowadays, there is no longer a technical reason for this. It is possible to explore a much wider range of sense responding projects, to broaden the horizon of sensitive interaction concepts (Bullivant 2006). What if the surfaces of our surroundings can actively change the way it feels to touch them? What if things like walls and furniture get the ability to interactively respond to our touch? What new dimensions of communication and esthetic experience will open up when we conceive of tangibility in this bi-directional way? This paper presents a prototype system aimed at exploring these very questions. The prototype consists of a grid of tangible embedded cells, each one combining three kinds of actuators to produce divergent touch stimuli. All cells can be individually controlled from an interactive computer program. By providing a layering of different combinations and impulse intensities, the grid structure enables altering patterns of actuation. Thus it can be employed to explore a sort of individual touch aesthetic, for which - in order to differentiate it from established types of aesthetic experiences - we have created the term 'Euhaptics' (from the Greek ŒµœÖ = good and Œ¨œÄœÑœâ = touch, finger). The possibility to mix a wide range of actuators leads to blending options of touch stimuli. The sense of touch has an expanded perception- spectrum, which can be exploited by this technically embedded superposition. The juxtaposed arrangement of identical multilayered cell-units offers blending and pattern effects of different touch-stimuli. It reveals an augmented form of interaction with surfaces and interactive material structures. The combination of impulses does not need to be fixed a priori; it can be adjusted during the process of use. Thus the sensation of touch can be made personally unique in its qualities. The application on architectural shapes and surfaces allows the user to feel the sensations in a holistic manner ‚Äì potentially on the entire body. Hence the various dimensions of touch phenomena on the skin can be explored through empirical investigations by the prototype construction. The prototype system presented in the paper is limited in size and resolution, but its functionality suggests various directions of further development. In architectural applications, this new form of overlay may lead to create augmented environments that let inhabitants experience multimodal touch sensations. By interactively controlling the sensual patterns, such environments could get a unique ‚Äútouch‚Äù for every person that inhabit them. But there may be further applications that go beyond the interactive configuration of comfort, possibly opening up new forms of communication for handicapped people or applications in medical and therapeutic fields (Grunwald 2001). The well-known influence of touch- sensations on human psychological processes and moreover their bodily implications suggest that there is a wide scope of beneficial utilisations yet to be investigated.

summary	In 1968 Aristid Lindenmayer proposed a series of mathematical constructs as a foundation for an axiomatic theory of form development. Since that time, Lindenmayer Systems or L-systems have evolved and found many practical applications in the computer visualization area. Generation of fractal imagery, realistic modeling and high quality visualization of organic forms and even music generation are now possible with the assistance of L-systems. But, is it possible to use L-systems in architectural design? Why would anyone use L-systems in architectural design? How would one use them? What could one expect from their use? In addition to providing answers to the above questions this paper presents: 1. Concepts behind L-systems 2. The need to transform L-Systems so they can have creative architectural application possibilities 3. Examples on the architectural use of L-Systems 4. Conclusions

title	A Multi-dimensional Exploration of Urban Attributes by Data Mining

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.
