Open Source Systems, Proceedings of 1st International Conference on Open Source Systems
No full textThis book contains most of the papers presented at the 1st International Conference on
Open Source Systems, held in Genova, Italy, July 2005.
The goal of OSS2005 has been to promote the exchange of new ideas, research and
applications in the emerging field of Open Source Software. Despite this was the first
edition of the conference, the number of contributions has been remarkably high. Also,
there has been a remarkable distribution of the submissions from all over the world:
there have been 53 accepted papers of 146 researchers coming from 22 countries. We
are proud to say that this is the best evidence that our goal has been satisfied.
Moreover, it demonstrates that Open Source Software is gaining more and more
momentum.
The volume is organized in 6 parts: papers, posters and experience report, the
ESPERTA session (in Italian), the demo summaries, the PhD research plans, and the
papers from the Educational Symposium. Then, each part is organized on thematic
sessions.
OSS2005 (and this volume) could have not have been done without the very valuable
support of several researchers, who volunteered their time for the success of the event.
Among the many, we would like to thank Jesus M. Gonzalez-Barahona (organizer of
the Open Educational Symposium and Barbara Russo (organizer of the Ph.D.
Symposium).
Special thanks also go to the members of the Organizing Committee, Francesco Di
Cerbo, Bruno Rossi, and Paolo Vernazza for their essential contributions to the OSS
2005 web site management and local organization.
We hope that you will have a very interesting and happy reading
Extracting and analyzing software code metrics from C# source code
No full textIn many software engineering areas, such as
software maintenance and software measurement,
source code analysis plays a key role. It represents a
fundamental step to acquire data that set up the basis
for different kind of analyses. Usually, a program is
analyzed through static or dynamic analysis and the
collected low level program information is abstracted
into a higher level representation. Such abstraction
layer should be general enough to allow different types
of analyses.
This paper proposes a high level representation to
abstract object-oriented and procedural source code
and presents an architecture and a tool to extract such
representation from C# source code. As a proof of
concept, an application in the domain of software
measurement is presented
Agile Technologies in Open Source Development
No full textThis book approaches two contemporary topics in the field of software engineering
that have had more than a significant impact in the way the modern software is
being developed. Agile movement raised the role of experience and people in the
centre stage having a profound impact on large and small software organizations
alike. Research and practice have shown that agile is penetrating practically in
all industrial domains including the globally operating, hardware-bound software
development.
Open source software development was considered to be outside of the scope
of professional software development practice for long time. Companies perceived
the voluntarily lead programming initiatives as something that could not be part of
their strategic goal setting or daily practice. Today, a great majority of the companies
utilize the open source solutions at many levels of the organization. The corporate
strategies often include a plan where part of the software product has been opened
for getting the benefits that are associated with the open source communities.
There are many similarities in agile and open source movements. They have taken
the field by surprise and gained a significant momentum that bear long lasting impact
on the practice of software development. Both were initiated by a small group of
practitioners. They are based on a value structure, which is far from the traditional
technology orientation of many other software engineering innovations. Finally, the
two approaches value people, collaboration, and excellence as the primary drivers
of software development.
This book shows you that open source and agile both deal with operational efficiency
approaching it from different but mutually supporting angles. The authoring
team has done a great job in highlighting the key differentiators and similarities
of the two approaches. This book stands out from the others by presenting solid
empirical evidence to support authors’ argumentation. Practitioners will find many
suggestions and guidance, and they can also see the rationale behind these ideas,
which further raises the value of this book
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
