    Augmenting Social Media Accessibility

    No full text
    The popularity of social media is affecting society as they are changing the way communication, collaboration, interaction, and information are produced and consumed. In current society, a debate is discussing whether social media can be seen as a powerful democratizing tool or as a powerful tool that will enlarge social differences. Far from settling this debate, in this paper we propose an architecture to bring social media into the massmedia mainstream. The proposed architecture, named SOMFA (SOcial Media For All), finds, gets, transforms, and enriches social media contents for a presentation over TV sets, so that people with technological, sociological, geographical, or physical limitations may enjoy social media and may participate to the social media revolution. A prototype implementation of SOMFA shows the feasibility of our approach, as Web social media can be seen and read as well as ordinary TV programs. By giving the opportunity to everyone to access to social media, SOMFA can be considered a democratic agent as it provides a novel service to society

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Bringing Multimedia Contents into MP3 Files

    The digital music revolution has improved the availability of music and made it easier to enjoy. The shift from hard support, such asaudio CDs, to software leaves some unsatisfied by the loss of additional media contents, such as images, lyrics, and CD cover. We propose to fill the gap by enriching e-music with multimediacontents. Our proposal focuses specifically on MP3 as a widely distributed open format. The challenge we meet in enriching MP3 lies in maintaining audio compatibility and avoiding file size explosion. To this end, we define a description language to express multimedia contents in a textual way, with higher representation efficiency than existing languages. We also address security issues that arise from the use of an open format. Effectiveness is shown with an MP3 player capable of rendering multimedia contents

    The Digital Restyling of Audiobooks

    Portable devices and wireless connections are creating a new scenario where digital information are massively entering our life. Such a scenario is craving for new applications and, in the meanwhile, several applications are simply re-written for the mobile scenario (we can check e–mail, browse the web, play games, etc.). In this paper we propose a mechanism to adapt a classical digital audiobook application to the new mobile scenario. Our proposal introduces, into a digital audiobook, multimedia objects (images and text) synchronized with the audio. The proposed mechanism does not modify the digital file structure and can be protected against piracy. With our mechanism, an audiobook is no longer a simple audio representation of a written book, but a different, complete multimedia product. The mechanism is shown to be effective through a modified audiobook player

    Variations on the Author

    “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
