The e-Archeo 3D project, an innovative and sustainable cultural proposal based on XR technologies
No full textThis contribution focuses on e-Archeo 3D: an application that visualises virtual archaeological reconstructions. It is an interactive browser-based application implemented on the open-source ATON platform. This application enables the visualisation of archaeological sites through 360° panoramas that can be explored and populated with multimedia content (audio, pictures, videos, and 3D models). Users can switch between the current archaeological context and the reconstruction hypothesis at each viewpoint while a voice (or text) narrates the main archaeological and historical information. Some parts of the panoramas pulsate with a yellow colour and give access to in-depth multimedia content. An additional visualisation level allows users to learn about the reliability of the reconstructions and the sources and interpretative processes on which they are based
DataSpace-ISPC: a Semantic Platform for Heritage Science
No full textThe contribution presents the DataSpace of the Institute of Heritage Science (ISPC) of the Italian National Council for Research. Cultural Heritage is well known to be a multidisciplinary domain where heterogeneous data, methods and techniques overlap, co-exist and collaborate to create evidence-based wisdom represented with local and (rarely) inter-operable standards. DataSpace aims to overcome the need to harmonise converging research perspectives, allow collaborative research, and debabelize the presentation of data. This horizontal perspective is based on a graph of knowledge, ruled by a semantic reference model, and acts as a glue to connect different digital resources created with different perspectives. The DataSpace, which is built on top of the Arches platform integrated and customised with original tools, has been validated with positive results against two case studies to cover the wider domain of Heritage Science. The contribution explains the activities and technological solutions adopted and goes into detail about the problems and limitations that arose with the implementation of the DataSpace offering a critical yet positive perspective on the use of the DataSpace-ISPC in production scenarios.Eurographics Workshop on Graphics and Cultural HeritageDigital Libraries and Infrastructure
ATON: An Open-Source Framework for Creating Immersive, Collaborative and Liquid Web-Apps for Cultural Heritage
Full text linkThe web and its recent advancements represent a great opportunity to build universal, rich, multi-user and immersive Web3D/WebXR applications targeting Cultural Heritage field—including 3D presenters, inspection tools, applied VR games, collaborative teaching tools and much more. Such opportunity although, introduces additional challenges besides common issues and limitations typically encountered in this context. The “ideal” Web3D application should be able to reach every device, automatically adapting its interface, rendering and interaction models—resulting in a single, liquid product that can be consumed on mobile devices, PCs, Museum kiosks and immersive AR/VR devices, without any installation required for final users. The open-source ATON framework is the result of research and development activities carried out during the last 5 years through national and international projects: it is designed around modern and robust web standards, open specifications and large open-source ecosystems. This paper describes the framework architecture and its components, assessed and validated through different case studies. ATON offers institutions, researchers, professionals a scalable, flexible and modular solution to craft and deploy liquid web-applications, providing novel and advanced features targeting Cultural Heritage field in terms of 3D presentation, annotation, immersive interaction and real-time collaboration
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
