Detecting Functional Requirements Inconsistencies within Multi-teams Projects Framed into a Model-based Web Methodology

One of the most essential processes within the software project life cycle is the REP (Requirements Engineering Process) because it allows specifying the software product requirements. This specification should be as consistent as possible because it allows estimating in a suitable manner the effort required to obtain the final product. REP is complex in itself, but this complexity is greatly increased in big, distributed and heterogeneous projects with multiple analyst teams and high integration between functional modules. This paper presents an approach for the systematic conciliation of functional requirements in big projects dealing with a web model-based approach and how this approach may be implemented in the context of the NDT (Navigational Development Techniques): a web methodology. This paper also describes the empirical evaluation in the CALIPSOneo project by analyzing the improvements obtained with our approach.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-RMinisterio de Economía y Competitividad TIN2015-71938-RED

Personalizing the web: A tool for empowering end-users to customize the web through browser-side modification

167 p.Web applications delegate to the browser the final rendering of their pages. Thispermits browser-based transcoding (a.k.a. Web Augmentation) that can be ultimately singularized for eachbrowser installation. This creates an opportunity for Web consumers to customize their Web experiences.This vision requires provisioning adequate tooling that makes Web Augmentation affordable to laymen.We consider this a special class of End-User Development, integrating Web Augmentation paradigms.The dominant paradigm in End-User Development is scripting languages through visual languages.This thesis advocates for a Google Chrome browser extension for Web Augmentation. This is carried outthrough WebMakeup, a visual DSL programming tool for end-users to customize their own websites.WebMakeup removes, moves and adds web nodes from different web pages in order to avoid tabswitching, scrolling, the number of clicks and cutting and pasting. Moreover, Web Augmentationextensions has difficulties in finding web elements after a website updating. As a consequence, browserextensions give up working and users might stop using these extensions. This is why two differentlocators have been implemented with the aim of improving web locator robustness

Un método de evaluación de usabilidad de mashups basado en la composicionalidad de sus componentes

[ES] Los Mashups son una nueva generación de aplicaciones Web que integran componentes provistos por terceros desde la Web. La usabilidad en este tipo de aplicaciones es un factor muy importante ya que como en toda aplicación Web, este determina el éxito de la aplicación. Si bien se han planteado métodos de evaluación que permiten evaluar la usabilidad de aplicaciones Web en general, éstos no cubren las características inherentes a la composicionalidad de los Mashups. La presente tesina de máster pretende aportar un método de evaluación de la usabilidad de Mashups acorde con sus características propias de composicionalidad. El método está compuesto de un modelo de usabilidad y un proceso de evaluación que provee guías sobre la forma en la que el modelo de usabilidad puede ser usado para realizar evaluaciones específicas. Tanto el modelo de usabilidad como el proceso de evaluación están alineados con el último estándar ISO/IEC 25000 para la evaluación de la calidad de producto (SQuaRE) y ambos toman en cuenta la naturaleza composicional de los Mashups. El modelo de usabilidad descompone el concepto de usabilidad en sub-características y métricas genéricas. Estas métricas son aplicadas en la composición del producto final y el método de evaluación puede ser aplicado en cualquier estado del ciclo de vida de este tipo de aplicaciones, ya sea en la selección de los componentes, durante el proceso de composición o cuando el producto está listo para ser usado. Para apoyar esta propuesta se ha realizado un profundo estudio del estado del arte. Este estudio comprende dos mapeos sistemáticos: el primero abarca un estudio de la evaluación de la calidad de los Mashups y el segundo cubre las características de la composicionalidad envueltas en los Mashups. Los resultados obtenidos aportaron de una forma significativa en la definición del Modelo de Usabilidad de Mashups y posteriormente en el proceso de evaluación de usabilidad. Finalmente, se desarrollaron tres casos de estudio que muestran la viabilidad de nuestro enfoque. Estos casos de estudio muestran en detalle como el método de evaluación propuesto utiliza nuestro Modelo de Usabilidad para Mashups. Los resultados muestran que nuestra propuesta permite detectar problemas de usabilidad, los cuales una vez corregidos, permiten obtener Mashups más usables[EN] Mashups are the new-generation of Web applications that integrates third-party components from the Web. Usability in these applications is very important since their success depends on this quality factor. Although several methods have been proposed to evaluate the usability of Web applications in general, they do not cover the specific characteristics inherent to the compositionality of Mashups. This master thesis aims to provide a method for evaluating the usability of Mashups according to their specific characteristics of compositionality. The method is composed of a usability model and an evaluation process that provides guidelines on how the usability model can be used to perform specific evaluations. Both the usability model and the evaluation process are aligned with the latest ISO/IEC 25000 standard for software product quality evaluation (SQuaRE), and both take into account the compositional nature of mashups. The usability model breaks down the concept of usability into sub-characteristics, attributes and generic metrics. These metrics are applied to the final product composition and process evaluation method can be applied at any stage of the life cycle of this kind of applications (i.e., during the component selection, the composition process or when the product is ready for use. In order to support the foundation of this proposal, an in-depth study was performed about the state of art. This study comprises two systematic mappings: the first one covers the quality evaluation of Mashups, whereas the second one covers the compositionality features involved in Mashups. The obtained results were used as input in order to define both our Mashups Usability Model, and our usability evaluation process. Finally, we developed three case studies in order to show the feasibility of our approach. These case studies show in detail how the proposed evaluation method was followed by using our Mashup Usability Model. Results showed that our approach was able to detect usability problems, which once corrected, it allows obtaining more usable Mashups.Cedillo Orellana, IP. (2013).

Challenges of migrating legacies web to mobile: A systematic literature review

The multi-device era comes thanks to mobile computing which gives remote access to resources from anywhere changing the people’s life and opening new business opportunities. However, the legacy systems do not render the content properly in mobile devices because they were thought to be only compliant with Web browsers. Economic availability is often the reason why these have not been modernized. This work proposes a systematic literature review about the approaches used for the portabilization or modernization of web 1.0 business applications to mobile devices in the period 2006-2017, from SCOPUS, IEEE, and ACM. The search obtained 824 articles, where 37 were selected based on the inclusion criteria. The research questions were: PI1. What have been the contribution to the portability of business applications to mobile devices? PI2. What methods have been used? PI3. What is the nature of the contribution found? PI4. What are the objectives that are pursued in the research work?. The conclusions were obtained through the classification of selected papers with respect to focus, scope, type of research and type of contribution to give an answer to research questions. Then, the state of the art determines the main approaches such as model-driven development, content reorganization, augmentation, and specific migrations. However, certain research gaps were detected and detailed which represent exploration opportunities.Fil: Cajas, Viviana. Universidad Tecnologica Indoamerica.; EcuadorFil: Urbieta, Mario Matías.

User Interface Adaptation Using Web Augmentation Techniques: Towards a Negotiated Approach

The use of Web augmentation techniques has an impact on tasks of owners of Web sites, developers of scripts and end-users. Because the Web sites can be modified by external scripts, their owners might lose control about how Web site contents are delivered. To prevent this, they might be tempted to modify the structure of Web pages thus making harder to execute external scripts. However, communities of Web augmentation scripters are increasing since end-users still have needs not yet covered by Web sites. In this paper we analyze the trade-offs of the introduction of Web augmentation scripts. In order to mitigate some negative effects, such as the loss of control, we propose an approach based on negotiation and coordination between actors involved in the process. We present a set of tools to facilitate the integration of scripts and to foster their dissemination for the benefit of all actors involved

Una propuesta de transformación M2M para el análisis de la fase ASM de MoWebA

En este trabajo presentamos cómo la adopción del ASM apoya la portabilidad del PIM y mantiene el modelo arquitectónico independiente de la plataforma de implementación. Para el efecto, adoptamos MoWebA, con sus reglas de transformación M2M que permiten la correcta generación de múltiples ASM partiendo del mismo PIM y múltiples PSM partiendo del mismo ASM. Así, el alcance de este trabajo es presentar las reglas de transformación PIM-ASM definidas en MoWebA para dos arquitecturas diferentes (Aplicaciones Enriquecidas de Internet y móviles) y mostrar su relevancia en pos de la reducción del problema de la portabilidad del PIM. Hemos seleccionado RIA y arquitecturas móviles debido a la relevancia y el impacto actual de ambas. Con este trabajo se logró comprobar que mediante transformaciones M2M es posible obtener modelos ASM para diferentes arquitecturas partiendo de un único PIM sin necesidad de modificarlo previamente. A pesar de que sólo fueron considerados dos modelos ASM (i.e., uno para RIA y otro para persistencia móvil), se concluyó que es completamente posible obtener modelos ASM para otras arquitecturas. La principal ventaja de obtener varios modelos ASM partiendo de un único modelo PIM es que la portabilidad del PIM se conserva de manera considerable y significativa. Es importante recordar que este enfoque (es decir, la captura de los elementos arquitectónicos en el modelo ASM), es muy diferente al de la mayoría de las metodologías actuales que, a diferencia de MoWebA, tienden a agregar los elementos específicos de la arquitectura al PIM (mediante la adaptación/extensión del mismo). Adicionalmente, este estudio muestra que mediante el uso de archivos de configuración externos es posible mejorar en gran medida el grado de automatización de las transformaciones PIM-ASM, más aún cuando es posible procesar estos archivos invocando código Java nativo.This study focuses on a model-to-model (M2M) transformation approach as a possible contribution for the portability problem, mainly at the conceptual modeling level. Therefore, we show as the adoption of Architectural Specific Model (ASM), an intermediate model between Platform Independent Model (PIM) and Platform Specific Model (PSM), supports the PIM portability and maintains the architectural model independent from the implementation platform. To exemplify the concept, we defined M2M transformation rules for MoWebA in order to automate transformations from PIM to ASM for different architectures. We show how to obtain different ASM models for two architectures (Rich Internet Applications and mobile) starting from the same PIM model with a semi-automatic process. Thus, we show the approach relevance to reduce the portability problem.Facultad de Informátic
