Transizioni d’immagini e architetture al tempo dell’IA. Modelli semantici in cerca di autore / Transitions of Images and Architectures in the Time of AI. Semantic Models in Search of an Author.
No full textLa ricerca presentata è l’ultimo esito di un lungo percorso di studio (tuttora in corso) incentrato sull’elaborazione del ruolo rappresentativo e conformativo [Unali 2018] del disegno per il ‘Modello Semantico’ in architettura e nel design [Unali, Caffio 2023], qui attualizzato rispetto alle più recenti innovazioni tecnoculturali introdotte soprattutto dal concetto di Intelligenza Artificiale, con le conseguenti progettualità interdisciplinari.
La ricerca è stata strutturata in due fasi elaborative, qui sintetizzate in tre capitoli.
Nella prima fase – ‘Rilevamento dello stato dell’arte’ – dopo aver studiato i principali antefatti e riferimenti concettuali e visivi che l’argomento attinge dalla storia della rappresentazione (e non solo), sono state catalogate e classificate alcune fra le molteplici progettualità elaborate sul tema da architetti, designer e artisti, evidenziando semantiche, metodi e tecniche di elaborazione.
Nella seconda fase della ricerca – ‘Sperimentazioni’ –, dopo delle prime prove applicative
prevalentemente di ordine estetico (modelli semantici) e tecnologico (metodi e tecniche)
– alimentate soprattutto dalle conoscenze acquisite nella precedente fase –, sono state predisposte delle progettualità tematiche rispetto a una struttura più matura che, fra ricerca e didattica, ci ha consentito di elaborare consapevoli ‘transizioni’ di immagini e spazi attraverso tecnologie riferibili in generale all’IA, affrontando così i vari aspetti aperti dall’argomento.
Autori: il contributo è stato articolato rispetto a tre ambiti tematici, ognuno trattato individualmente da un autore.
Il primo tema, ‘Modelli semantici in cerca di autore, fra Soft Machine e Hard Machine’ è stato elaborato da Maurizio Unali, e introduce alcuni aspetti fondativi inerenti la struttura dell’intera ricerca, analizzando i principali risultati raggiunti e evidenziando alcuni possibili sviluppi.
Il secondo tema, ‘Dal riconoscimento di immagini al text-to-image fino text-to-3D’ è stato elaborato da Giovanni Caffio, e partendo da un excursus sullo sviluppo delle tecnologie computazionali arriva poi ad evidenziare alcune fra le più interessanti progettualità elaborate nell’ambito dei rapporti fra la rappresentazione architettonica e IA.
Infine, il contributo di Fabio Zollo, dal titolo ‘Metodi e tecniche di elaborazione: exempla’, illustra le principali tecnoculture utilizzate per elaborare le immagini e gli spazi realizzati nel corso della ricerca
Towards a Virtual Museum of Ephemeral Architecture: Methods, Techniques and Semantic Models for a Post-digital Metaverse / Verso un museo virtuale dell’architettura effimera: metodi, tecniche e modelli semantici per un metaverso post-digitale
No full textPresentiamo gli ultimi esiti di una sperimentazione, fra ricerca e didattica, sul tema del Virtual Museum (VM), riflettendo sul flusso di lavoro e sui modelli semantici utilizzati per la realizzazione del suo Metaverso, nella consapevolezza delle potenzialità oggi offerte dalle tecnoculture post-digitali.
Sin dagli esordi negli anni 80’, l’idea interdisciplinare di VM, seguendo le conquiste tecnologiche dei tempi, esplora molteplici dimensioni confor-mative dello spazio digitale, sperimentando vari sistemi di visualizzazione e diverse forme di interazione, sia online, sia offline. Dall’ormai storico Virtual Museum commissionato dalla Guggenheim Foundation nel ‘99 al-lo studio Asymptote Architecture (Hani Rashid & Lise Anne Couture), al grande tema della conservazione ed esposizione del patrimonio digitale (cfr. la Carta per la conservazione del patrimonio digitale dell'UNESCO del 2003) – ricordiamo, ad es., la mostra Archaeology of the Digital, curata da Greg Lynn nel 2013 per il Canadian Centre for Architecture di Montréal –, fino all’odierna proposta del Virtual Museum NFTism dello studio Zaha Hadid Architects, emerge un’affascinante avventura delle idee che soprat-tutto nella rappresentazione trova le ragioni del suo essere spazio abitabile.
The essay summarises the latest results of an experiment, between research and didactics, on the general theme of the Virtual Museum (VM) in architecture and design (Fig. 1), explaining the workflow used and the semantic models elaborated for the realisation of a prototype (called VM5), conceived as a thematic metaverse of ephemeral architecture. In order to summarise the main outcomes of the carried out research, the contribution has been articulated with respect to three main thematic areas addressed in the study, each treated individually by one author. The first theme— Sect. 2. The State of the Art Survey: Conceptual Map, Timeline—was elaborated by Giovanni Caffio, and summarises the project and the contents of the conceptual map and timeline realised, where the most significant works were classified, also attempting to highlight the different types of application and use of the VM. In the third part of the experimentation.
The second topic—Sect. 3. The VM Project of Ephemeral Architecture, Between Research and Teaching—was elaborated by Maurizio Unali, and introduces some of the foundational aspects inherent to the structure of the entire research, summarising the design contents that nourished the realisation of the VM5 prototype, both in compositional terms and with respect to the type of fruition experience. The main results achieved are also analysed and some possible developments are highlighted— Sect. 4. The Processing of the Workflow to Realise the VM5 Prototype, here written by Fabio Zollo, the methods and techniques (workflow) used to realise the VM5 project were defined, a graduation theme of the same author, elaborated within the five-year degree thesis workshop in Architecture (a. a. 2021/22), coordinated by Professors G. Caffio and M. Unali, of the Department of Architecture of the University G. d’Annunzio of Chieti-Pescara (Figs. 2, 3, 4, 5, 6, and 7)
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
