Improving Software Comprehension through an Automated Dependency Tracer
No full textThe paper presents ANALYST, a tool that automates impact analysis by exploiting a framework that implements dependency based software representation models. The preliminary experimental results show that it supports the improvement of software representation models to be used in software comprehension. Moreover, the tool allows the maintainer to perform more accurate and correct changes, decreasing the software degradation effect. Finally, it is shown that the tool can be used as a general platform for experimenting with different impact analysis approaches, and for assessing and comparing their effectiveness with the use of suitable metric
Software Model for Impact Analysis: a Validation Experiment
No full textImpact analysis is the process of identifying software work-products that may be affected by proposed changes. This requires a software representation model that can formalize the knowledge about the various dependencies between work-products.This study was carried out with the aim of objectively assessing whether the effectiveness of an impact analysis approach depends on the software dependency model employed. ANALYST, a tool for impact analysis, was used to implement different impact analysis approaches. The results show that the nature of the components and the traceability relationships employed for impact analysis influence the effectiveness of the approach, but different traceability models affect the various aspects of effectiveness differently. Moreover, this influence is independent of the software development approach, but is sensitive to software quality decay
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
An Explanatory Case Study about the Maintenance Effectiveness of Traceability Models
No full textAnalysis of the role of traceability models in software maintenance and comprehension is an important research issue. An exploratory case study evaluating the relationship between the granularity of the traceability model adopted and the effectiveness of the maintenance process is presented in this paper. Two maintenance effectiveness aspects were taken into account: efficiency and accuracy. The analysis was carried out in an object-oriented environment, with the support of an integrated platform of software tools. The preliminary results show that some aspects of the effectiveness of the maintenance process can be improved by modifying the degree of granularity of the model. These results encourage further research into this topic, while some additional side effects that emerged from the study will also be investigated
