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.

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.

Producing Just Enough Documentation: The Next SAD Version Problem
No full textSoftware architecture knowledge is an important asset in today´s projects, as it serves to share the main design decisions among the project stakeholders. Architectural knowledge is commonly captured by the Software Architecture Document (SAD), an artifact that is useful but can also be costly to produce and maintain. In practice, the SAD often fails to fulll its mission of addressing the stakeholders´ information needs, due to factors such as: detailed or high-level contents that do not consider all stakeholders, outdated documentation, or documentation generated late in the lifecycle, among others. To alleviate this problem, we propose a documentation strategy that seeks to balance the stakeholders´ interests in the SAD against the efforts of producing it. Our strategy is cast as an optimization problem called "the next SAD version problem (NSVP) and several search-based techniques for it are discussed. A preliminary evaluation of our approach has shown its potential for exploring cost-benefit tradeoffs in documentation production.Fil: Diaz Pace, Jorge Andres.

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.

Producing Just Enough Documentation: An Optimization Approach Applied to the Software Architecture Domain
Full text linkThe Software Architecture is an important asset in a software development process, which serves to share and discuss the main design concerns among the project stakeholders. The architecture must be properly documented (e.g., via a Wiki environment) to be effectively used by these stakeholders. However, the process of producing architecture documentation often fails to deliver contents that address the stakeholders’ information needs. To address the problem, we argue for a knowledge management strategy in which: (i) architecture documentation is created incrementally; and (ii) its contents are driven by a model of stakeholder preferences. In this work, we present an information optimization approach applied to the architecture documentation domain, derived from an existing documentation method called Views & Beyond. To do so, we define the Next SAD Version Problem (NSVP) and then provide tool support to assist architects in producing cost-effective documentation. Based on prior work, we perform a sensitivity analysis of the optimization model and develop a robust formulation that takes into account uncertainty in the parameter estimations for NSVP instances, thus improving the outcomes of our documentation assistant.Fil: Diaz Pace, Jorge Andres.

Personalized architectural documentation based on stakeholders' information needs
Full text linkThe stakeholders of a software system are, to a greater or lesser extent, concerned about its software architecture, as an essential artifact for capturing the key design decisions of the system. The architecture is normally documented in the Software Architecture Document (SAD), which tends to be a large and complex technical description, and does not always address the information needs of every stakeholder. Individual stakeholders are interested in dierent, sometimes overlapping, subsets of the SAD and they also require varying levels of detail. As a consequence, stakeholders are aected by an information overload problem, which in practice discourages the usage of the architectural knowledge and diminishes its value for the organization. Along this line, this work presents a semi-automated approach to recommend relevant contents of a given SAD to specific stakeholder profiles. Our approach assumes that SADs are hosted in Wikis, which not only favor communication and interactions among stakeholders, but also enable us to apply User Profiling techniques to infer stakeholders´ interests with respect to particular documents. We have built a recommendation tool implementing our approach, which was tested in two experiments with Wiki-based SADs. Although preliminary, the results have shown that the recommendations of the tool help to nd the architectural documents that best match the stakeholders´ interests.Fil: Tommasel, Antonela.

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
KAgent: Un agente de interfaz para el soporte al usuario de Data Mining
Full text linkUno de los procesos de KDD (Knowledge Discovery in Databases), denominado Minería de Datos, puede ser conceptualizado como una secuencia de actividades, técnicas o algoritmos que tienen como propósito general la extracción de conocimiento interesante de un conjunto de datos triviales. La posibilidad de combinar aleatoriamente estas técnicas sin un adecuado entrenamiento o como mínimo, un esquema de asistencia, no permite aprovechar el potencial de las herramientas de Software disponibles. En este trabajo, se propone una solución con la utilización de: la tecnología de Agentes Inteligentes, Cadenas de Markov y el método AHP. En base a ello, se diseña un esquema de asistencia inteligente para usuarios que deseen practicar Minería de Datos, que permita recolectar y transferir el conocimiento de usuarios experimentados. Considerando la actual variedad de herramientas para KDD, se optó por el diseño de un framework con el fin de desarrollar una solución que sea aplicable a cierto rango de dichas herramientas. Finalmente, se implementó un esquema concreto para KNIME, el cual permitió llevar a cabo algunas pruebas para medir la utilidad efectiva del asistente.Sociedad Argentina de Informática e Investigación Operativ
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
