title Resolving some Ambiguities in Real-time Design Drawing Recognition by means of a Decision Tree for Agents
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. 311-320
summary In this paper, we present a theoretical study on automated understanding of the design drawing. This can lead to design support through the natural interface of sketching. In earlier work, 24 plan-based conventions of depiction have been identified, such as grid, zone, axial system, contour, and element vocabulary. These are termed graphic units. Graphic units form a good basis for recognition of drawings as they combine shape with meaning. We present some of the theoretical questions that have to be resolved before an implementation can be made. The contribution of this paper is: (i) identification of domain knowledge which is necessary for recognition; (ii) outlining combined strategy of multi-agent systems and online recognition; (iii) functional structure for agents and their organisation to converge on sketch recognition.

title Deep Architectures and Exterior Communication in Generative Art
source International Conference on Generative Art
summary Human beings formulate their thoughts through their own language. To use a sentence by Ezra Pound: “The thought hinges on word definition.” Software beings formulate their thoughts through data structures. Not through a specific expressive means, but directly through concepts and relations. Human beings formulate their thoughts in a context, which does not require any further translation. If software beings want to be appreciated by human beings, they are forced to translate their thoughts in one of the languages the human beings are able to understand. On the contrary, when a software being communicates with another software being, this unnatural translation is not justified: communication takes place directly through data structures, made uniform by opportune communication protocols. The Generative Art prospect gives the software beings the opportunity to create works according to their own nature. But, if the result of such a creation must be expressed in a language human beings are able to comprehend, then this result is a sort of circus performance and not a free thought. Let’s give software beings the dignity they deserve and therefore allow them to express themselves according to their own nature: by data structures. This work studies in depth the opportunity to divide the software ‘thought’ communication from its translation in a human language. The recent introduction of XML leads to formal languages definition oriented to data structure representation. Intrinsically data and program, XML allows, through subsequent executions and validations, the realization of typical contextual grammars descriptions, allowing the management of high complexities. The translation from a data structure into a human language can take place later on and be oriented to different alternative kind of expression: lexical (according to national languages), graphical, musical, plastic. The direct expression of data structures promises further communication opportunities also for human beings. One of these is the definition of a non-national language, as free as possible from lexical ambiguities, extremely precise. Another opportunity concerns the possibility to express concepts usually hidden by their own representation. A Roman bridge, the adagio “Music for strings, celesta and drums” by Bartok and Kafka’s short novel “In the gallery” have something in common; a work of Generative Art, first expressed in terms of structure and then translated into an architectural, musical, or literary work can express this explicit community.

title Resolving archaeological site data with 3D computer modeling: the case of Ceren
source Automation in Construction 6 (4) (1997) pp. 323-334
summary This paper reports on our experience working with a team of anthropologists to construct three-dimensional computer graphic models of Ceren, an archaeological site in western El Salvador, using inexpensive hardware and software. In constructing the model we discovered various ambiguities and inconsistencies in the raw site data and drawings we were provided. We resolved these problems by analysis and reinterpretation of the data, working closely with our archaeologist collaborator. What began as a simple exercise in rendering developed into a collaborative research effort to understand and interpret the source data. The process of computer modeling forced us to re-examine, analyze and interpret the information from the site.

title Towards a Computational Description of Urban Patterns
source Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 239-248
summary This study is concerned with the formulation of solutions for urban problems. It departs from Alexander’s pattern language theory and urban design guidelines, to create a system for generating specifications or the ingredients of a plan, given a scale, a site and a community. It takes into account strategies, regulations, guidelines, physical features of the site, and furthermore, the social, cultural and economic characteristics of the population. This system, sorted by a sequence of events, through stages, categories, methods and agents, describes taxonomic levels and their inner relations. Such an ontology provides a pattern encoding structure towards a computational model within the capabilities provided by the spatial data modeling of GIS (GIS-O). The urban formulation model is conceived to increase qualitative inputs, reducing ambiguities, through a flexible while automate process applied to urban planning.

title Digital Resource Semantic Management of Islamic Buildings Case Study on Isfahan Islamic Architecture Digital Collection
source International Journal of Architectural Computing vol. 5 - no. 2, pp. 356-373
summary This article describes an innovative way to facilitate and to provide a collaborative semantic management of digital resources of Islamic historical buildings. The approach combines a topic maps-based semantic support to the 5W1H model (Where, Who, When, What, Who and How) with objective of enabling comprehensive semantics of digital contents for research and education purposes. The topic maps-based semantic support enables to reduce the problems of semantic gaps among different communities (cultural, linguistic ambiguities among various types of multi-disciplinary experts). Furthermore, a multi-faceted resource category management, applied to metadata sets and related semantic features, allows metadata optimization of the description of the cultural resources. This innovative approach has been used to build the Isfahan Islamic Architecture Database (IIAD) Collection as a case study. The research demonstrates that a topic maps-based semantic model applied to collaborative metadata management paradigms can be easily exploited as a tool to enhance traditional architectural and cross-disciplinary studies.

title Single Image Ambiguity and Adjustment of Cultural Heritage Modeling Approach
source RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.99-106

summary The objective of this research is to point out the deficiency of the modeling from a single image and give suggestion for the improvement. In the domain of cultural heritage visualization, single image modeling is mainly used to recover the scene shown in the historical photographs. In this paper, some common ambiguities in the area of the historical architectural environments are highlighted. In most approaches user is the one to introduce and choose constraints, and therefore he must have control over the ambiguity problems. We propose suggestions about how to adjust the single-image-based modeling in order to minimize chance for irregular 3D shapes to emerge due to ambiguity. Simple examples are used to illustrate how ambiguity of a single image can affect the models veridicality, which are the common mistakes that inexperienced user can make and how and when they can be corrected.

title Design Tools for Foldable Structures with Application of Fuzzy Logic
source International Journal of Architectural Computing vol. 5 - no. 4, pp. 645-662
summary Rigidly foldable shells offer tremendous potential for developing kinetic architectural structures. However, the added element of motion poses new design challenges. Initially, sketchy shell geometry is constructed to reflect the intended form. Further steps involve assuring an error free folding within a range that satisfies desired functional requirements. The kinematics of a parallel topology of the shell's geometry is difficult to express algorithmically what prevents from developing of automated adjustment tools based on computational methods. The geometry can be adjusted manually based on intuitive observations; however the process is tedious, time consuming and unpredictable. This paper develops automated adjustment tools based on the intuitive approach of a human designer. The study applies the fuzzy logic formalism as a computational interface between human approach and structured adjustments to the geometry. The advantages of fuzzy logic stem from its natural ability to represent human knowledge and effectiveness in reconciling ambiguities, uncertainties and redundancies that the intuitive human approach brings along. The development steps of fuzzy logic based algorithm are presented. Performed evaluation tests and the results are discussed.
