No full textResource production of written forms of Sign Languages by a user centered editor, SWift (SignWriting improved fast transcriber)
No full textThe SignWriting improved fast transcriber (SWift), presented in this paper, is an advanced editor for computer aided writing and transcribing using the SignWriting (SW; Sutton, 1995). The application allows the users to compose and save the desired sign using the SW elementary components, called “glyphs”, guided through a fully automated procedure which makes the composition process fast and intuitive. The SWift has the ambitious goal of helping to break down the “electronic” barriers that keep the deaf community away from the web (Borgia, 2010). The editor has been developed in a modular way, so it can be integrated everywhere the use of the SW as an alternative to written “verbal” language may be advisable
ARMob - Augmented reality for urban mobility in RMob
No full textThis paper describes the design and development of a location-based Augmented Reality (AR) application for mobile devices. The application provides real time data about transportation in a urban area. It can be set along the line of the continuous creation of richer and more complex interaction modalities between users and data. A relevant element in this strategy is the visual enrichment of the real scene perceived though the mobile camera, by superimposing to it a set of user-relevant information. In the presented work, this information is related to nearby bus stops and to the arrival of next buses. More details, such as routes, distances etc. can be displayed on demand in order to gain awareness of the surrounding infomobility data. The presented application is included in a multiservice framework named RMob, developed for the city of Rome. © 2012 ACM
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
Stories and signs in an e-learning environment for deaf people
No full textAn important field for model-driven development of interfaces is the consideration of users with disabilities. Interface design for deaf people presents specific problems, since it needs to be based on visual communication, incorporating unusual forms of interaction, in particular gesture-based ones. Standard solutions for model-driven development of visual interfaces lack specific constructs for structuring these more sophisticated forms of interaction. This paper discusses such issues in the context of the development of a deaf-centered e-learning environment. Sign Languages enter this context as a suitable alternative communication code, both in video form and through one of their most successful written forms, namely SignWriting. © 2012 Springer-Verlag
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
