A Visual Evolution Explorer Visualize a Release History Database
No full textI would like to thank all the people who have supported me and have contributed directly or indirectly to the success of this thesis. Special thanks go to Professor Harald Gall for giving me the chance to write this diploma thesis, and to Christoph Bommer who kindly supported the thesis with the ressources and data of Siemens. Many thanks also to Martin Pinzger for his advice and encouragement and for the valuable feedback for the draft of this document. Many thanks to my parents for proof reading and for their continuous support during my studies. In this thesis we present the design and implementation of a plugin for the Eclipse platform that provides facilities for visualizing the history of a software project. The plugin integrates a frontend for a Release History Database (RHDB) into the Eclipse IDE and provides interfaces for data importers and extension points for visualization modules. The plugin includes a tree map module suitable for visualizing hierarchical data such as the metrics of files contained in
Navigation of Source Code Data
No full textFirst and foremost, I would like to thank Martin Pinzger for his imperturbable calm and his reassurances during the dark hours of scientific research. Next, where would I be without the tenacious companionship of Michael Würsch and Andreas Jetter through all these days. Your good spirits and helpfulness is unheard of. Thanks, you two. Special thanks to Beat Fluri for his both gracious and generous support in my hour of need. Further thanks to Patrick Knab for postgreSQL support and constantly taking away the Eclipse book — I have my own copy now. Additional thanks to my parents who, to my constant surprise, never seem to loose faith in me... And finally, thanks to my sister, Simone, for proof-reading my work. Source code data of large software systems tend to be very complex. To visualize and navigate these data pools, in a manner to reveal specific software traits, remains a challenge to date. In this thesis we present an exploration strategy for navigating such source code data. We generate graphical views that expose specific design aspects, such as bad smells, and hotspots in general. The approach uses sequences of such views to incrementally gather knowledge about the code in scope. This finally allows us to identify entities of questionable design. Our approach uses the measurement mapping principle combined with kiviat diagrams to visualize system entities. We further present a prototype implementation as an Eclipse plug-in and evaluate it in a case study, analyzing parts of the Mozilla source code.

Models of OSS project meta-information: a dataset of three forges
No full textThe process of selecting open-source software (OSS) for adoption is not straightforward as it involves exploring various sources of information to determine the quality, maturity, activity, and user support of each project. In the context of the OSSMETER project, we have developed a forge-agnostic metamodel that captures the meta-information common to all OSS projects. We specialise this metamodel for popular OSS forges in order to capture forge-specific meta-information. In this paper we present a dataset conforming to these meta-models for over 500,000 OSS projects hosted on three popular OSS forges: Eclipse, SourceForge, and GitHub. The dataset enables different kinds of automatic analysis and supports objective comparisons of cross-forge OSS alternatives with respect to a user's needs and quality requirements
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
