SlideWiki – A Platform for Authoring FAIR Educational Content
No full textSlideWiki.org is a Web-based OpenCourseWare (OCW) authoring system that enables educators and learners to collaborate on creating, sharing, re-using and re-purposing multi-lingual open educational content. The SlideWiki platform allows people to author FAIR(Findable, Accessible, Interoperable, and Reusable) educational content.SlideWiki supports many features to semantically-enrich educational con-tent to support FAIR authoring. In this paper we will present those features of the platform such as Linked Data interface, manual and automatic content annotation as well as content linking and metadataSee CEUR version on http://ceur-ws.org/Vol-2198/paper_108.pd
Learning for Verification in Embedded Systems: A Case Study
No full textVerification of embedded systems is challenging whenever control programs rely on black-box hardware components. Unless precise specifications of such components are fully available, learning their structured models is a powerful enabler for verification, but it can be inefficient when the system to be learned is data-intensive rather than control-intensive. We contribute a methodology to attack this problem based on a specific class of automata which are well suited to model systems wherein data paths are known to be decoupled from control paths. We test our approach by combining learning and verification to assess the correctness of grey-box programs relying on FIFO register circuitry to control an elevator system
Automatic Test-Pattern Generation for Grey-Box Programs
No full textIn the context of structural testing, automatic test-pattern generation (ATPG) may fail to provide suites covering 100% of the testing requirements for grey-box programs, i.e., Applications wherein source code is available for some parts (white-box), but not for others (black-box). Furthermore, test suites based on abstract models may elicit behaviors on the actual program that diverge from the intended ones. In this paper, we present a new ATPG methodology to reduce divergence without increasing manual effort. This is achieved by (i) learning models of black-box components as finite-state machines, and (ii) composing the learnt models with the white-box components to generate test-suites for the grey-box program. Experiments with a prototypical implementation of our methodology show that it yields measurable improvements over two comparable state-of-the-art solutions
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
