Mining interests for user profiling in electronic conversations
Full text linkThe increasing amount of Web-based tasks is currently requiring personalization strategies to improve the user experience. However, building user profiles is a hard task, since users do not usually give explicit information about their interests. Therefore, interests must be mined implicitly from electronic sources, such as chat and discussion forums. In this work, we present a novel method for topic detection from online informal conversations. Our approach combines: (i) Wikipedia, an extensive source of knowledge, (ii) a concept association strategy, and (iii) a variety of text-mining techniques, such as POS tagging and named entities recognition. We performed a comparative evaluation procedure for searching the optimal combination of techniques, achieving encouraging results.Fil: Nicoletti, Matías Alberto.

An optimization-based tool to support the cost-effective production of software architecture documentation
Full text linkSome of the challenges faced by most software projects are tight budget constraints and schedules, whichoften make managers and developers prioritize the delivery of a functional product over other engineeringactivities, such as software documentation. In particular, having little or low-quality documentation of thesoftware architecture of a system can have negative consequences for the project, as the architecture is the main container of the key design decisions to fulfill the stakeholders? goals. To further complicate thissituation, generating and maintaining architectural documentation is a non-trivial and time-consuming activity.In this context, we present a tool approach that aims at (i) assisting the documentation writer in their tasks and (ii) ensuring a cost-effective documentation process by means of optimization techniques. Ourtool, called SADHelper, follows the principle of producing reader-oriented documentation, in order to focus the available, and often limited, resources on generating just enough documentation that satisfies the stakeholders?concerns. The approach was evaluated in two experiments with users of software architecture documents, with encouraging results. These results show evidence that our tool can be useful to reduce the documentation costs and even improve the documentation quality, as perceived by their stakeholders.Fil: Nicoletti, Matías Alberto.

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
Towards Software Architecture Documents matching Stakeholders' Interests
Full text linkArchitecture documentation is a crucial activity in any software development project. In practice, architecture documenters face two problems: how to generate relevant documentation contents for the main stakeholders, and how to avoid documenting too much about the architecture. We propose a personalization approach based on stakeholders' interests to tackle these problems. The expected contribution is to facilitate the documenter?s tasks, while making the resulting documentation useful to the stakeholders. We specifically describe a user profiling tool that builds stakeholders? profiles, which serve to link the stakeholders to sections of the architectural documents. These links help the documenter to prioritize sections that are potentially relevant to those stakeholders. The tool has been implemented as a semi-automated pipeline based on text mining techniques. The results, although preliminary, show that our proposal is helpful for a stakeholder-centric architecture documentation process.Fil: Nicoletti, Matías Alberto.

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
