No full textHeritage Building Information Modeling (HBIM)
No full textBuilding Information Modelling (BIM) is a process that has become an essential reference in the AEC architecture, engineering and construction sector (BIM Toolkit 2014-15; EUBIM Taskgroup, 2017; 2014/24/EU; UNI 11337:2017). The reasons for this growing interest are due to its undisputed potential as a control upon the entire process of new building design, construction, maintenance, management, and disposal. Thanks to parametric objects enriched with both qualitative and quantitative information, BIM led to the development of a new way of working: a process based on real time interaction between all stages of the building process, where the BIM informative model is the inter-operable shared 3D interface that enables architectural, structural and systems computing.
However, historical buildings are the result of modification and stratification processes carried out over time. They are the witnesses of historical events and of cultures that have occurred over the centuries; therefore they embody tangible and intangible values. The study of architectural heritage is based on an history-critical methodological approach. The survey of the building plays an essential role: according to archival documentation, and geometrical and constructive analysis, interpretative models describe the architectural, historical, and material characteristics. This different methodological approach to architectural heritage is not fully supported by BIM software and platforms, designed to manage processes for new buildings. Therefore, the study of the potential offered by BIM for documentation, conservation, interpretation, presentation, enhancement, maintenance, management, and restoration design is an open field.
In recent years, many studies used BIM applied to existing buildings, and the wording HBIM (intended both as Historical BIM or Heritage BIM) has emerged and is currently used. The main issues that need studying relate to: exhaustive and economic as-built 3D modeling of historic settlements (often with complex shapes) from point clouds; modeling architectural and constructive elements realized with craft procedures; their parametrization and computing into BIM environments; implementing historical databases.
In conclusion, the HBIM procedure requires a different theoretical–methodological approach from the original BIM. Architectural heritage (from ancient times to the recent past), constitutes a large part of the world's built heritage. BIM offers a potential operative and methodological revolution in building studies and design, therefore defining solutions, workflows, protocols, and best practices for HBIM is not only a current hot topic but also a necessity.

Scan-to-BIM for architectural heritage enhancement and preservation. Leading techniques and advanced automation processes
Full text linkThe digitisation of Architectural Heritage emerges as a pivotal and groundbreaking
practice crucial for the preservation and enhancement of cultural assets.
This significance becomes particularly pronounced in an era marked by profound
transformations and challenges across multiple fields.
By cutting-edge technologies within a scenario dominated by Artificial Intelligence,
which disrupts established paradigms and approaches, this initiative aims to address
the inherent challenges of long-term conservation. Simultaneously, it aspires to
achieve the broader objective of ensuring enhanced access and a more enriched experience
of historical monuments for both current and future generations, thereby
safeguarding their unique identities.
Heritage's vulnerability must be carefully weighed to strike a delicate balance between
accessibility and contemporary interpretation on the one hand, and authenticity and
integrity on the other. The hazards of digitisation, including the potential loss of stored
information or intentional obsolescence, are closely related to this susceptibility as
well as physical material modifications.
The present thesis, born out of these critical considerations, adopts comprehensive
and multidisciplinary approaches to delve into diverse themes converging within the
realm of architectural survey and drawing for heritage virtualisation.
Through extensive field research conducted in both Italy and Spain, the combined
methodologies of various surveying techniques and technologies, including LiDAR
and Photogrammetry, are thoroughly examined as foundational elements for the digital
acquisition of historical monuments. The resulting data, presented as point clouds,
images, and/or polygonal models, undergo a detailed processing and optimisation
phase employing semi-automatic procedures.
These procedures, primarily focusing on the semantic enrichment of architectural and
structural components, are geared towards facilitating an in-depth analysis of the
conservation status of the monument. This, in turn, translates into improved information management, providing crucial
support for subsequent phases involved in constructing the replicated model of the
architectural masterpiece.
Moving beyond the survey activity, the investigation advances towards Heritage Building
Information Modelling (HBIM) through the adoption of a Scan to BIM approach.
The latter is seamlessly integrated into a unified protocol, streamlining data processing
while ensuring adherence to health and safety regulations for the operator.
This methodology enables a thorough analysis and faithful digitisation of the reproduced
case studies, leveraging metric and geometric references guaranteed by the instrumentation
used, as well as semantic segmentation and classification of data derived
from the automations.
The proposed processes of automation, designed to accelerate processing times,
control operational costs, and enhance the precision and accuracy of results, are meticulously
crafted. Simultaneously, due consideration is given to the experience and
expertise of the operator involved in the activities, ensuring a thoughtful and conscious
approach throughout all stages of the process
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
The Cooperation Human-Machine : educating for creativity in the AI Age
No full textThis article’s aim is to start a reflection on how creativity can be educated with AI. The starting point is the concept of creativity and the synthetic reconstruction of the history of its relationship with technology. On this basis, we go further analyzing the relationship between AI and creativity, before indicating a possible work path for education. The conclusions concern the role of the author and creative production
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
