Mashups são aplicaçõesWeb criadas a partir da composição de recursos heterogêneos disponíveis na Web. Eles são considerados uma das principais tecnologias da Web 2.0, baseando-se nos princípios de criação de conteúdo pelo usuário final, cooperação e reuso. Esses princípios são aplicados através de sistemas de mashups, que consistem em aplicações que permitem que um usuário final realize composições de recursos sem a necessidade de habilidade em desenvolvimento de software. A aplicação de tecnologias da Web 2.0, em especial dos mashups, no gerenciamento de redes é potencialmente vantajosa, principalmente em cenários onde um administrador deve lidar com múltiplas ferramentas de gerenciamento de forma integrada. Entretanto, não há nenhuma investigação prévia da aplicação dessas tecnologias no gerenciamento. Essa investigação é o trabalho desenvolvido na presente dissertação. Para tal, uma arquitetura para um sistema de mashups de gerenciamento de redes é proposta. Com base nessa arquitetura, um protótipo desse sistema é descrito. Esse protótipo é utilizado na criação de mashups para dois cenários reais de gerenciamento de redes. A criação desses mashups permitiu a avaliação tanto da arquitetura quanto do protótipo. Nessa avaliação, é realizada uma comparação entre a criação dos mashups utilizando o protótipo e o desenvolvimento ad hoc (i.e., sem o uso de sistemas de mashups) dos mesmos. Além disso, é realizada uma avaliação qualitativa dos mashups criados, baseada em critérios como facilidade de implementação e utilização, extensibilidade, flexibilidade e confiabilidade. Os resultados das avaliações realizadas indicam que a tecnologia de mashups é tanto aplicável quanto vantajosa no contexto de gerenciamento de redes, ainda que a maioria das vantagens dessa aplicação dependam da existência de um sistema de mashups que permita que administradores criem suas próprias composições. / Mashups are Web applications created through the integration of external resources available on the Web. They have been considered a hallmark of Web 2.0 technologies, allowing end users to develop their own applications and encouraging cooperation and reuse. However, their usage in the network management field remains unexploited. In this context, we look at Web 2.0 as a feasible mechanism able to integrate heterogeneous management information. In this dissertation, we propose an architecture and a system prototype that allows network administrators to design their own management applications through the composition of external resources. The creation of mashups for two network management scenarios allowed us to evaluate both our architecture and our prototype. In this evaluation, we compare the development of network management mashups using our prototype and in an ad hoc fashion. We also perform a qualitative analysis of our mashups, based on characteristics such as ease-of-implementation, ease-of-use, extensibility, flexibility and reliability. The results of our evaluation indicate that mashups are, indeed, both applicable and advantageous in the context of network management, but the advantages of such application largely depend on a mashup system that enables administrators to create their own mashups.

<p>The purpose of this study is to analyze and understand how music festivals in Sweden are marketed today and the changes that will and may occur in the future. Music festivals are a common phenomenon in Sweden today and since most of them only are arranged once a year it gives the marketing of them a special character. Therefore I find it interesting to look at how the development of the Internet will change the marketing of music festivals. This study is based on a qualitative method where I have performed eight interviews with people who have given me their thoughts about this subject. The gathered material and my conclusions of this study are presented in chapter 4 and 5 and for further knowledge about this I recommend you to take a closer look at those chapters.</p>

Organizations today are adopting business intelligence (BI) systems at a fast pace with the expectation that these systems will help them make better business decisions and improve their performance. But with the ever changing industry dynamics and variable business needs of end-users, the BI requirements of organizations are also getting unpredictable and increasingly harder to deliver by the service providers. Additionally, the advancement of web 2.0 & enterprise 2.0 technologies has opened up more possibilities for the development of user-centric innovative business applications. Enterprise BI Mashups are a specific breed of such technologies that have the potential to empower end-users with self-service capabilities and facilitate problem-solving in ad-hoc situational BI scenarios. This research project attempts to explore the current landscape of Business Intelligence (BI) Mashups and to identify gaps in technology with respect to user requirements and corporate objectives. Through an empirical investigation of BI mashups use cases, specific issues and challenges associated with the use of mashups in BI have been ascertained. Working in collaboration with IBM Cognos, we have formulated a taxonomy and utility framework for Enterprise BI Mashups. The formulated taxonomy provides a basic framework for understanding the domain of BI mashups and is aimed to aid application development initiatives for creating BI mashups toolkits. The utility framework draws upon real-world use cases for BI Mashups as well as pertinent software design patterns that can facilitate the development of BI mashup tools and services. These frameworks are expected to advance an understanding of business process requirements that can be satisfied through the use of Enterprise BI Mashups, and also aid in the development of mashup toolkits targeted at BI end-users.

The increasing amount and variety of data available in the web leads to new possibilities in end-user focused data analysis. While the classic data base technologies for data integration and analysis (ETL and BI) are too complex for the needs of end users, newer technologies like web mashups are not optimal for data analysis. To make productive use of the data available on the web, end users need easy ways to find, join and visualize it. We propose a domain specific language (DSL) for querying a repository of heterogeneous web data. In contrast to query languages such as SQL, this DSL describes the visualization of the queried data in addition to the selection, filtering and aggregation of the data. The resulting data mashup can be made interactive by leaving parts of the query variable. We also describe an abstraction layer above this DSL that uses a recommendation-driven natural language interface to reduce the difficulty of creating queries in this DSL.

The success of Web services comes from the benefits that it brings in reducing the cost and the time needed to develop data and applications by reusing them, and simplifying their integrations through standardization. However, standardization in Web services does not remove the need for adapters due to possible heterogeneity among service interface and protocol definitions. Moreover, the current service APIs are targeted toward professional programmers, but not accessible to a wider class of users without programming expertise, but would never the less like to build their own integrated applications. In this dissertation, we propose methods and tools to support both service developers and non-expert users in their data and application integration tasks. To support service developers, we propose a framework that enables rapid development of Web service adapters. We investigate particularly the problem of service adaptation focusing on business interface and protocol layers. Our study shows that many differences between business interfaces and protocols are recurring. We introduce mismatch patterns to capture these recurring differences and provide solutions to resolve them. We present the notion of adaptation aspects, which is based on the aspect-oriented programming paradigm, to enable rapid development and deployment of service adapters. We also present a comparative study between standalone and aspect-oriented adapters development. The study shows that the aspect-oriented approach is preferable in many cases, especially when adapters need to access internal states of services. The proposed approach is implemented in a prototype tool, which is used to illustrate how it simplifies adapters development through a case study. To support users without programming expertise, we propose a spreadsheet-based Web mashups development framework, which enables users to develop mashups in the popular spreadsheet environment. First, we provide a mechanism that makes structured data first class values of spreadsheet cells. Second, we propose a new component model that can be used to develop fairly sophisticated mashups, involving joining data sources and keeping spreadsheet data up to date. Third, to simplify mashup development, we provide a collection of spreadsheet-based mashup patterns that captures common Web data access and spreadsheet presentation functionalities. Users can reuse and customize these patterns to build spreadsheet-based Web mashups instead of developing them from scratch. Fourth, we enable users to manipulate structured data presented on spreadsheet in a drag-and-drop fashion. Finally, we have developed and tested a prototype tool to demonstrate the utility of the proposed framework.

Como contexto para o estudo, escolheram-se os eventos das Jornadas de Junho de 2013, caracterizadas tanto pela emergência repentina de massivos protestos de rua no Brasil, quanto pela publicação, em sites de redes sociais, de uma grande quantidade de remixes e mashups contendo enunciados políticos a respeito. Compõem o corpus empírico da pesquisa 88 textos verbovisuais desse tipo, publicados no Facebook entre junho e julho de 2013. Entendidos como frutos de percursos de desmontagem e remontagem, e, portanto, de desressemiotização, esses textos foram analisados com base na articulação (proposta como objetivo teórico do trabalho) entre as categorias da Semiótica Social para a multimodalidade e as da Teoria Ator-Rede para translações. Como objetivo empírico, buscou-se descrever os significados representacionais e os percursos de constituição das montagens do corpus, em relação ao regime de enunciação da política. As perguntas de pesquisa foram duas, a saber: (1) quais foram os principais actantes mobilizados nos remixes estudados, e em que tipo de processos semióticos tais actantes apareceram com maior frequência?; e (2) quais foram algumas das operações de ressemiotização empregadas nas desreestabilizações sucessivas das diferentes versões de Brasil e realidade brasileira constituídas nesses textos? Os resultados elencaram as figurativizações mais comuns e os processos representacionais mais frequentes no corpus, em que os manifestantes, a nação brasileira, os políticos e a grande mídia foram os principais actantes representados, em geral, através de processos atributivos simbólicos. Destacou-se, nesse levantamento, a figura do gigante de pedra se levantando no Rio de Janeiro, empregada por muitos como representação unificada do Brasil e dos interesses múltiplos em atuação nas Jornadas. A partir dessa figura, descreveram-se ainda os processos de negociação de affordances para constituição de alguns dos textos analisados, e sua relação com as disputas pelo significado dos acontecimentos das Jornadas de Junho, e pela definição que era "ser brasileiro" no momento dos protestos. Como conclusão, os dados refletem a necessidade de buscar caminhos para compreensões menos deterministas da relação entre política, tecnologias digitais e sociedade, e modos de formação cidadã, no âmbito das mídias digitais, que viabilizem a compreensão de enunciados políticos como fruto de enredamentos semióticos sempre articulados em disputas de interesse, mesmo quando se pretendem neutros / Abstract: The main goal of the present study is to suggest ways of understanding the relation between digital culture and contemporary political action, based on the connection, drawn in the field of Applied Linguistics, between the notion of digital language as process and the concept of politics as a regime of enunciation which aims to translate the interests of many into one. The events of the June Journeys in 2013 were taken as context for the study, since they included not only the sudden emergence of massive protests on Brazilian streets, but also the publishing, on social network sites, of large amounts of remixes and mashups containing political statements on that regard. Seen as the outcomes of disassembling and assembling trajectories, and therefore, of deresemiotization trajectories, those texts were analyzed in the light of an articulation (also presented as a theoretical objective of this work) between Social Semiotics studies on multimodality and Actor-Network Theory principles for the understanding of translations. As empirical objectives, this work aimed to describe the representational meanings and the assembling trajectories of the texts in the corpus, in relation to the political regime of enunciation. The research questions were two: (1) what were the main actants mobilized in the remixes in the corpus, and in which kind of semiotic processes those actants appeared more often?; and (2) what were some of the resemiotization operations used for the continuous derestabilizations of different versions of Brazil and Brazilian reality represented in those texts? Results enroll the most frequent figurativizations and the most usual representational processes in the corpus, in which the demonstrators, Brazilian nation, politicians and mass media were the main actants, and were depicted, in general, through symbolic attributive processes. In that enrollment, the image of a stone giant rising in Rio de Janeiro was prominent, for it was used by many as a unified depiction of Brazil as a whole and of the multiple interests acting during the Journeys. From that picture, the results described the processes of negotiation of affordances for the composition of some of the analyzed texts, and their relation to the disputes for the meaning of the June Journeys events, and for what meant "to be Brazilian" then. As a conclusion, data reflects the need of pursuing less determinist ways of understanding the relation among politics, digital technologies and society, as well as the need for ways of citizenship education, regarding digital media, that address the understanding of political statements as outcomes of semiotic entanglements which are always connected to interests in dispute, even when allegedly neutral / Mestrado / Linguagem e Sociedade / Mestre em Linguística Aplicada
