Document changes: Modeling, detection, storage and visualization (Dchanges 2014)
No full textThe DChanges series of workshops focuses on changes in all their aspects and applications: algorithms to detect changes, models to describe them and techniques to present them to the final users are only some of the topics we investigate. The workshop is open to researchers and practitioners from industry and academia. In this edition, we will follow up on the discussion of DChanges 2014 about algorithms and interfaces to better understand and exploit detected changes, and about standards for modeling and transmitting changes. Particular attention will also be given to the use of these techniques in digital humanities-for instance in the studies of collation, text genetics and plagiarism detection-and for real-time collaborative editing
Vector Graphics: From PostScript and Flash to SVG
Full text linkThe XML-based specification for Scalable Vector Graphics (SVG), sponsored by the World Wide Web consortium, allows for compact and descriptive vector graphics for the Web.
SVG s domain of discourse is that of graphic primitives whose optional attributes express line thickness, fill patterns, text size and so on. These primitives have very different properties from those of traditional document components (e.g. sections, paragraphs etc.) that XML is normally called upon to express.
This paper describes a set of three tools for creating SVG, either from first principles or via the conversion of existing formats. The ab initio generation of SVG is effected from a server-side CGI script, using a PERL library of drawing functions; later sections highlight the problems of converting Adobe PostScript and Macromedia s Shockwave format (SWF) into SVG
Document changes: Modeling, detection, storage and visualization (DChanges 2018)
No full textThe DChanges series of workshops focuses on changes in all their aspects and applications: algorithms to detect changes, models to describe them and techniques to present them to the users are only some of the topics that are investigated. This year, we would like to focus on collaboration tools for non-textual documents. The workshop is open to researchers and practitioners from industry and academia. We would like to provide a platform to discuss and explore the state of the art in the field of document changes. One of the goals of this year's edition is to review the outcomes of the last four editions and to develop plans for the future
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
Browsing Agents: Automated Browsing of Distributed Information
No full textThis paper describes a tool kit for finding and remembering information in a distributed environment of rapidly-changing information sources. In these conditions users often expend significant amounts of effort searching for useful documents and objects, only to find that their information quickly becomes out-of-date and they need to start all over again. Browsing agents are designed to minimise this wasted effort by helping users to create and execute complex queries that mimic many aspects of browsing and searching. The queries may be stored and repeated later without user intervention
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
