A Study on the Influencing Factors of Social Media in the Communication of Cultural Heritage Education: A Systematic Literature Review

This study examined the impact of social media on disseminating cultural heritage education. After reviewing two databases, 29 articles met our inclusion criteria. This study found that social media can expand the educational scope of cultural heritage and increase public awareness and interest in cultural heritage tourism sites and museums. However, social media is only a publicity channel. It is necessary to consider five influencing factors in social media: the subject of information distribution, the motivation of distribution, the purpose of distribution, the content of distribution, and the method of distribution, and to analyze the specific practices of social media in disseminating cultural heritage education. Therefore, more research is needed to explore the influence of social media on cultural heritage education dissemination, to explore the educational nature of social media in cultural heritage education communication, and to provide a theoretical basis for social media to promote cultural heritage education dissemination

Incremental communication patterns in online social groups

In the last decades, temporal networks played a key role in modelling, understanding, and analysing the properties of dynamic systems where individuals and events vary in time. Of paramount importance is the representation and the analysis of Social Media, in particular Social Networks and Online Communities, through temporal networks, due to their intrinsic dynamism (social ties, online/offline status, users’ interactions, etc.). The identification of recurrent patterns in Online Communities, and in detail in Online Social Groups, is an important challenge which can reveal information concerning the structure of the social network, but also patterns of interactions, trending topics, and so on. Different works have already investigated the pattern detection in several scenarios by focusing mainly on identifying the occurrences of fixed and well known motifs (mostly, triads) or more flexible subgraphs. In this paper, we present the concept on the Incremental Communication Patterns, which is something in-between motifs, from which they inherit the meaningfulness of the identified structure, and subgraph, from which they inherit the possibility to be extended as needed. We formally define the Incremental Communication Patterns and exploit them to investigate the interaction patterns occurring in a real dataset consisting of 17 Online Social Groups taken from the list of Facebook groups. The results regarding our experimental analysis uncover interesting aspects of interactions patterns occurring in social groups and reveal that Incremental Communication Patterns are able to capture roles of the users within the groups

Serious Games and Mixed Reality Applications for Healthcare

Virtual reality (VR) and augmented reality (AR) have long histories in the healthcare sector, offering the opportunity to develop a wide range of tools and applications aimed at improving the quality of care and efficiency of services for professionals and patients alike. The best-known examples of VR–AR applications in the healthcare domain include surgical planning and medical training by means of simulation technologies. Techniques used in surgical simulation have also been applied to cognitive and motor rehabilitation, pain management, and patient and professional education. Serious games are ones in which the main goal is not entertainment, but a crucial purpose, ranging from the acquisition of knowledge to interactive training.These games are attracting growing attention in healthcare because of their several benefits: motivation, interactivity, adaptation to user competence level, flexibility in time, repeatability, and continuous feedback. Recently, healthcare has also become one of the biggest adopters of mixed reality (MR), which merges real and virtual content to generate novel environments, where physical and digital objects not only coexist, but are also capable of interacting with each other in real time, encompassing both VR and AR applications.This Special Issue aims to gather and publish original scientific contributions exploring opportunities and addressing challenges in both the theoretical and applied aspects of VR–AR and MR applications in healthcare

Guidelines for the Management of Cultural Heritage Using 3D Models for the Insertion of Heterogeneous Data

[ES] La Gestión del Patrimonio Cultural (GPC) es una operación muy compleja cuyo objetivo es preservar la integridad física de los Bienes Culturales y, al mismo tiempo, difundir los valores históricos y permitir el disfrute del Patrimonio. Debido a las múltiples fases que componen la GPC (documentación, intervención, conservación preventiva, uso), el gestor se ve sometido a un gran esfuerzo de coordinación de las interacciones creadas por figuras profesionales muy diferentes, tanto por formación como por necesidades específicas en el ámbito de la gestión. En los últimos años, la aplicación de las tecnologías digitales al Patrimonio Cultural se ha convertido en una parte indispensable de la GPC. Las metodologías más utilizadas para la adquisición de datos, como el escaneo láser terrestre y la fotogrametría digital, también se han convertido en una práctica habitual en las actividades profesionales. Sin embargo, el uso de modelos 3D para la gestión se limita hasta ahora a algunas investigaciones académicas, que a menudo no tienen continuidad tras la finalización del proyecto. Además, hasta la fecha existen pocas normas supranacionales que guíen a las instituciones en el proceso de creación y uso de modelos 3D para la GPC. Por tanto, la falta de herramientas para controlar la calidad de los datos y productos digitales adquiridos afecta negativamente a la interacción entre el sector de la investigación académica, el sector de la gestión y el mundo profesional. La investigación propone el uso de los modelos 3D como una herramienta válida de apoyo en todas las fases de la gestión, ya sea utilizando los datos tridimensionales como base del archivo digital, o explotando todos los productos obtenidos a partir de los datos básicos para las múltiples acciones de cada fase. Por lo tanto, el objetivo de la tesis doctoral es desarrollar directrices para la producción de modelos 3D con el fin de gestionar, introducir y preservar eficazmente los datos. Estas directrices investigan todos los aspectos del proceso que va desde la adquisición de datos, pasando por su catalogación y archivo, hasta su tratamiento y la creación de un sistema de información simplificado para su gestión. Cada directriz guía al usuario a través de una fase específica del tratamiento y el uso de los datos digitales, y proporciona indicaciones adaptadas al nivel de conocimientos respecto a las tecnologías y metodologías digitales. De este modo, el gestor puede utilizar los modelos 3D para su gestión y controlar su calidad y sus estándares mínimos. Se ha optado por un enfoque interdisciplinar e internacional con el fin de elaborar directrices que se adapten al mayor número posible de Bienes Culturales, desarrollando la tesis en el marco de un acuerdo de cotutela entre la Universidad de Bolonia y la Universitat Politècnica de València. Con el fin de obtener unas pautas universales, las metodologías analizadas en el estudio del estado del arte se aplicaron a una serie de casos de estudio. Los principales son los monumentos paleocristianos de Rávena (Italia), pertenecientes a la Lista del Patrimonio Mundial de la UNESCO, y un panteón neogótico situado en Castellón de la Plana (España). Las experiencias realizadas sobre la GPC en los dos países han contribuido a la elaboración de directrices y normas universales que mejoren las interacciones entre el mundo académico, los gestores y el sector profesional. La investigación, al poner de manifiesto los problemas inherentes a la GPC, ha permitido identificar las principales cuestiones abiertas que se deben explorar en futuras líneas de investigación, como la aplicación de estándares a un gran número de Bienes Culturales para conducir a la puesta a punto de los mismos estándares; la búsqueda de sistemas para la clasificación automática de los datos brutos; el tratamiento de los datos recogidos para la creación de relaciones, estrategias y métodos de clasificación, integración y optimización de datos heterogéneos.[CA] La Gestió del Patrimoni Cultural (GPC) és una operació molt complexa l'objectiu de la qual és preservar la integritat física del els Béns Culturals i, al mateix temps, difondre els valors històrics i permetre el gaudi del Patrimoni. A causa de les múltiples fases que componen la GPC (documentació, intervenció, conservació preventiva, ús) , el gestor es veu sotmés a un gran esforç de coordinació de les interaccions creades per figures professionals molt diferents, tant per formació com per necessitats específiques en l'àmbit de la gestió. En els últims anys, l'aplicació de les tecnologies digitals al Patrimoni Cultural s'ha convertit en una part indispensable de la GPC, des de les fases de documentació fins a les d'intervenció. Les metodologies més utilitzades per a l'adquisició de dades, com l'escaneig làser terrestre i la fotogrametria digital, també s'han convertit en una pràctica habitual en les activitats professionals. No obstant això, l'ús de models 3D per a la gestió es limita fins ara a algunes investigacions i aplicacions acadèmiques, que sovint no tenen continuïtat després de la finalització del projecte. A més, fins a la data hi ha poques normes supranacionals que guien a les institucions en el procés de creació i ús de models 3D. Per tant, la falta de ferramentes per a controlar la qualitat de les dades i productes digitals adquirits afecta negativament la interacció entre el sector de la investigació acadèmica, el sector de la gestió i el món professional. La investigació proposa l'ús dels models 3D com una ferramenta vàlida de suport en totes les fases de la gestió, ja siga utilitzant les dades tridimensionals com a base de l'arxiu digital, o explotant tots els productes obtinguts a partir de les dades bàsiques per a les múltiples accions de cada fase. Per tant, l'objectiu de la tesi doctoral és desenrotllar directrius per a la producció de models 3D a fi de gestionar, introduir i preservar eficaçment les dades. Estes directrius investiguen tots els aspectes del procés que va des de l'adquisició de dades, passant per la seua catalogació i arxiu, fins al seu tractament i la creació d'un sistema d'informació simplificat per a la seua gestió. Cada directriu particular guia l'usuari a través d'una fase específica del tractament i l'ús de les dades digitals, i proporciona indicacions adaptades al nivell de coneixements respecte a les tecnologies i metodologies digitals. D'esta manera, el gestor pot utilitzar els models 3D per a la seua gestió i controlar la seua qualitat i els seus estàndards mínims. S'ha optat per un enfocament interdisciplinari i internacional a fi d'elaborar directrius que s'adapten al nombre més gran possible de tipus de Béns Culturals Cultural, desenrotllat la tesi en el marc d'un acord de cotutela entre la Universitat de Bolonya i la Universitat Politècnica de València. A fi d'obtindre unes pautes universals, les metodologies analitzades en l'estudi de l'estat de l'art es van aplicar a una sèrie de casos d'estudi. Els principals són els monuments paleocristians de Ravenna (Itàlia), pertanyents a la Llista del Patrimoni Mundial de la UNESCO, i una capella neogòtica situada a Castelló de la Plana (Espanya). Les experiències realitzades sobre la GPC en els dos països han contribuït a l'elaboració de directrius i normes universals que milloren les interaccions entre el món acadèmic, els gestors i el sector professional. La investigació, al posar de manifest els problemes inherents a la GPC, permet identificar les principals qüestions obertes que s'han d'explorar en futures línies d'investigació, com l'aplicació d'estàndards a un gran nombre de Béns Culturals per a conduir a la posada al punt dels mateixos estàndards; la busca de sistemes per a la classificació automàtica de les dades brutes; el tractament de les dades arreplegats per a la creació de relacions, estratègies i mètodes de classificació, integració i optimització de dades heterogènies.[EN] The Management of Cultural Heritage (MCH) is a very complex operation aimed at protecting the physical integrity of Cultural Heritage assets, while promoting their historical value and development of tourism industry. Composed by distinct phases (documentation, intervention, monitoring and use), MCH implies a great effort for the project manager to coordinate the interactions among very different professional figures. In recent years, the use of digital technologies has become an essential part of the MCH delicate process, from early documentation to late intervention phases. The most commonly used methodologies for digital data acquisition, such as terrestrial laser scanning and digital photogrammetry, have become common practice in a broad range of professional activities. On the contrary, the use of 3D models for MCH is still limited to few academic research to date, often lacking continuity and wide application after the end of specific projects. Furthermore, very few supra-national standard guidelines regulating their use are available to date. As a consequence, the operator who decides to use a 3D model as a basis for management is faced with the scarcity and fragmentation of standards and guidelines. Moreover, the lack of standard on quality of acquired data and digital products negatively influences the interaction between the academic research sector, the managers and the professional world. The focus is on the use of 3D models as a valid support tool in the MCH process, highlighting their advantages in all the distinct phases of the management. As an example, 3D data can constitute themselves the basis for the digital database, gathering all available information concerning a Cultural Heritage site, exploitable for restoration works or for scientific dissemination. In particular, the aim of this PhD research is to develop guidelines to produce 3D models for MCH, with the purpose to efficiently entry, store and manage digital data. The here provided guidelines investigate every aspect of the process leading from data acquisition to cataloguing and archiving, processing and creation of a simplified information system. Each recommendation guides the user through the management of digital data, by adapting to his/her level of knowledge with respect to digital technologies and methodologies. In this way, the manager can efficiently use 3D models in MCH projects. In order to elaborate guidelines that could be suitable for as many typologies of Cultural Heritage as possible an international approach was chosen, developing the thesis in joint supervision under the University of Bologna and the Universitat Politècnica de València. We decided to apply state-of-the-art technologies and methodologies to a variety of case studies. The main ones are the early Christian monuments of Ravenna (Italy) belonging to the UNESCO World Heritage List, and a small neogothic chapel located in Castellón de la Plana (Spain). The fruitful collaboration between two different countries allowed an invaluable exchange of MCH expertise and, more broadly, contributed to the elaboration of standardized and universally applicable MCH guidelines that will allow a better interaction between managers, the academic research world and the professional one. The investigation, by highlighting the problems inherent to the MCH, made it possible to identify the main open issues that need to be explored in future lines of research, such as the application of standards to a large number of cultural assets in an iterative, continuous and automatic way, in order to perfecting the standards; the search for automatic classification of raw data; the processing of collected data for the creation of relations, strategies and methods for the classification, integration and optimisation of heterogeneous data.Bertacchi, G.

Representation Challenges

Augmented 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. In the last few years, the AR/AI expansion and relationship have raised deep transdisciplinary speculation. The research experiences have shown many cross-relations in Architecture and Design domains. Representation studies could arise an international debate as a convergence place of multidisciplinary theoretical and applicative contributions related to architecture, city, environment, tangible and intangible Cultural Heritage. This book collects 66 papers and identify eight lines of research that may guide future developments

Sensing the Cultural Significance with AI for Social Inclusion

Social Inclusion has been growing as a goal in heritage management. Whereas the 2011 UNESCO Recommendation on the Historic Urban Landscape (HUL) called for tools of knowledge documentation, social media already functions as a platform for online communities to actively involve themselves in heritage-related discussions. Such discussions happen both in “baseline scenarios” when people calmly share their experiences about the cities they live in or travel to, and in “activated scenarios” when radical events trigger their emotions. To organize, process, and analyse the massive unstructured multi-modal (mainly images and texts) user-generated data from social media efficiently and systematically, Artificial Intelligence (AI) is shown to be indispensable. This thesis explores the use of AI in a methodological framework to include the contribution of a larger and more diverse group of participants with user-generated data. It is an interdisciplinary study integrating methods and knowledge from heritage studies, computer science, social sciences, network science, and spatial analysis. AI models were applied, nurtured, and tested, helping to analyse the massive information content to derive the knowledge of cultural significance perceived by online communities. The framework was tested in case study cities including Venice, Paris, Suzhou, Amsterdam, and Rome for the baseline and/or activated scenarios. The AI-based methodological framework proposed in this thesis is shown to be able to collect information in cities and map the knowledge of the communities about cultural significance, fulfilling the expectation and requirement of HUL, useful and informative for future socially inclusive heritage management processes

Nel corso degli ultimi anni l’applicazione delle tecnologie digitali ai Beni Culturali è diventata una parte imprescindibile nella GPC, ma l’uso dei modelli 3D per la gestione è finora limitato ad alcune ricerche e applicazioni accademiche. Inoltre, ad oggi sono pochi gli standard con carattere sovranazionale che guidano gli Enti nel procedimento di creazione e uso dei modelli tridimensionali per la GPC. Il gestore che decide di utilizzare un modello 3D come base per la gestione si scontra con la scarsezza e la frammentarietà di standard e indicazioni in tale ambito. L’obiettivo della tesi è quello di elaborare linee guida per la produzione di modelli 3D per un’efficace gestione, inserimento e conservazione dei dati. Tali linee guida indagano ogni aspetto del processo che porta dall’acquisizione del dato, alla sua catalogazione e archiviazione, al suo processamento e alla creazione di un sistema informativo semplificato per la gestione. Per arrivare all’elaborazione di linee guida che si adattino a più tipologie possibili di Beni Culturali è stato scelto un approccio interdisciplinare e internazionale, sviluppando la tesi in regime di cotutela tra l’Università di Bologna e l’Universitat Politècnica de València, e applicando lo stato dell'arte delle tecnologie di acquisizione, elaborazione e utilizzo dei modelli 3D ad una varietà di casi studio. Il percorso di ricerca ha permesso di individuare le principali questioni aperte che devono essere approfondite in futuro, come l’applicazione di standard a un alto numero di Beni Culturali; la ricerca di sistemi per la classificazione automatica dei dati grezzi; l’elaborazione dei dati raccolti per la creazione di relazioni, strategie e metodi per la classificazione, l’integrazione e l’ottimizzazione di dati eterogenei.La Gestión del Patrimonio Cultural (GPC) es una operación muy compleja cuyo objetivo es la conservación de la integridad física del Patrimonio y la difusión de los valores históricos.
