Representation Challenges: The Reasons of the Research
Full text linkAugmented Reality (AR) and Artificial Intelligence (AI) are technological domains that closely interact with space at architectural and urban scale in the broader ambits of cultural heritage and innovative design. The growing interest is perceivable in many fields of knowledge, supported by the rapid development and advancement of theory and application, software and devices, fueling a pervasive phenomenon within our daily lives. These technologies demonstrate to be best exploited when their application and other information and communication technology (ICT) advancements achieve a continuum. In particular, AR defines an alternative path to observe, analyze and communicate space and artifacts. Besides, AI opens future scenarios in data processing, redefining the relationship between man and computer
Machine Learning for Cultural Heritage Classification
Full text linkCultural Heritage (CH) assets may be defined as integrated spatial systems composed of interconnected shapes. The classification and organization of geometries within a hierarchical system are functional to their correct interpretation, which is often performed using 3D point clouds. The recurring shapes recognition becomes a crucial activity, nowadays accelerated by Machine Learning (ML) procedures able to associate semantic meaning to geometric data. An interdisciplinary research team [1] has developed a ML supervised approach, tested on the Milan Cathedral and Pomposa Abbey datasets, which presents an innovative multi–level and multi–resolution classification (MLMR) process. The methodology improves the learning activity and optimizes the 3D classification by a hierarchical concept
METODICHE INTEGRATE DI RILIEVO 3D PER L’ANALISI DI ARCHITETTURE COMPLESSE. IL CASO DELL’ABBAZIA DI POMPOSA. INTEGRATION OF DIFFERENT METHODOLOGIES FOR THE HIGH RESOLUTION SURVEY OR COMPLEX ARCHITECTURES. THE POMPOSA ABBEY CASE STUDY
No full textNel campo del rilievo architettonico l'integrazione fra differenti metodi di acquisizione digitale tridimensionali consente di sopperire ai limiti dei singoli approcci per ottenere modelli sempre più completi, dai quali poter estrarre un numero di informazioni utili per differenti analisi. Questo contributo presenta una metodologia di rilievo integrata fra strumenti attivi e passivi, applicati da terra e da drone, al fine di ottenere un modello multi-risoluzione completo. Il caso studio oggetto della sperimentazione è l'Abbazia di Pomposa, a Codigoro (FE).
In the field of digital 3D survey, integration among different methodologies and technologies offers the opportunity to overcome lacks of single techniques, building more complete and faithful 3D models and therefore deriving information that can be used for different kind of investigations. This contribution shows an integrated methodology between active and passive technologies applied from terrestrial and UAV point of views, aimed at creating complete and multi-resolution 3D models. The selected case study is the Pomposa Abbey, located near Ferrara, Italy
Lo spazio inventato. Ricerche e sperimentazioni in Lombardia: spazi, manufatti, scene
No full textPerspective, a milestone of the Renaissance, characterizes the visual culture of the West and plays an important role until the unhinging of the unity of space by the twentieth-century avant-gardes. Its application to the configuration of real space accompanies the development of modern architecture, rooting some
contemporary design installations to history.
In Milan its application had an experimental approach from the beginning, destined to affect the development of the arts in the following centuries. Bramante marked its evolution in the relationship between the built and represented space that characterizes the perspective choir of ‘Santa Maria presso San Satiro’, conceived as an integration of the real space.
This new solution paved the way for the birth of theatrical scenography and the great season of quadrature in interior decoration, where the architectura picta integrates the physical space in which the observer is located. The geometric coherence of the projection makes the fiction different from the real room, experimenting with the application of varied architectural and projective models
in the search for useful techniques to speed up the realization. The result was the development of practical artifices to make the spatial illusion more effective, in a completely different way from the theatrical scenography, in which the fiction was obvious. The perspective game spreads to the smaller scales of the architectural furnishings and scenographic apparatuses with creations, which anticipate by a few centuries the research of the Gesamstungwerk that will characterize the dawn of contemporary art. In this way the Bramante’s legacy reflects in the roots that will lead to the flowering of interior design
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
