Special issue on Semantic Technologies for Collaborative Web (Editorial)
No full textThis Special Issue brings together the achievements and the experiences of researchers and practitioners from several areas, including organizational and collaborative systems that leverage Web 2.0, agent architectures, infrastructures for dynamic collaboration, the SOA and the Semantic Web, cloud computing as well as policies and mechanism for security, privacy and safety of smart systems. The aim is to gather the state-of-art research on adaptation, control, decision making and knowledge management in smart systems. A special focus is on the technological solutions that exploit agile, adaptive and reconfiguration characteristics to address unexpected circumstances and evolving scenarios that arise in smart systems
Web2Touch 2017: Semantic technologies in smart information sharing and web collaboration
Full text linkThis report presents Web2Touch 2017, a Track at the 26th IEEE WETICE Conference. This year Web2Touch completed 10 editions focusing on scientific and practical works about semantic web as a support for collaborative platforms in their need for sharing knowledge. Web2Touch is an open forum for studies in multiple application domains including, for example, web science, health systems, collaborative learning, smart cooperative systems, and web collaboration and communication in general. Web2Touch 2017 includes five full papers and one short paper. The overall focus of the contributions is on the research of how semantics can improve information sharing, services, and collaboration on "the new web"
Web2Touch 2016: Evolution and security of collaborative web knowledge
No full textThis report introduces the Web2Touch 2016, a Track at the 25th IEEE WETICE Conference. This track involves works from collaborative web knowledge research community and related themes. Web2Touch 2016 explores the state-of-the-art on users' practical experiences, as well as trends and research topics paving the way for future collaborative approaches to knowledge management. Papers come from areas such as computational analysis, management of contextual information, support to personalized information management, collaborative knowledge production, consistency, knowledge engineering and security modeling for multiple knowledge sources. The overall focus is on determining how to route, organize, and present contextual and meaningful information and services to facilitate 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
Web2Touch 2018: Semantic Technologies in Smart Information Sharing and Web Collaboration
Full text linkWe present Web2Touch 2018, one of the Tracks at the 27th IEEE WETICE Conference. Web2Touch 2018 includes five full papers and one short paper tackling very up-to-date issues in information sharing and collaboration, including, among others, big data analytics, development of virtual agents and assistants, privacy and security analysis and evaluation. Papers come from areas such as knowledge engineering, linked data, big data, security, safety, and web science. The overall focus is on how research on semantics coupled with crucial topics such as big data analysis, privacy, knowledge representation, and enterprise contents management, among the others, can improve services and collaboration and push forward new ways of interpreting the role of the web
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
