Description
Summary:=== Online Social Media services (blogs, social networks) are important communication tools in the modern world. Tradicionally, people find information in the web by browsing or searching. With the recent success of Online Social Media, people started to receive information from conversations with their friends. A huge and diverse amount of information is generated everyday by millions of people all over the world. As an example, on Twitter users share and forward information about events in real-time; on Facebook, users get to know about what their friends did on the last weekend; and on Fourquare users discover where their friends visited recently. The huge volume of data, the diversity of information, the dynamic of the systems, and the need for real-time information leads to big challenges while processing and analyzing the user generated data from Online Social Media services. However, a better understanding about the information diffusion process in Online Social Media services is necessary, not only for users, but also for companies and researchers. Advertising, better content organization, and creation of new tools are examples of possible benefits from a better understanding of the problem. In this work we propose MIOSphere, a system to monitor, in real-time, the diffusion of information through popular Online Social Media services. Furthermore, a wide characterization of the diffusion of URLs on Twitter was done, analyzing not only the internal diffusion, but also how URLs generated in external services (YouTube videos, for example) diffuses on Twitter. === Com o recente sucesso das mídias sociais online (blogs, redes sociais), as pessoas passaram a encontrar informações na Web através de conversas com seus amigos. Uma quantidade enorme e diversa de informação é gerada diariamente por milhões de pessoas em todo o mundo. Processar e analisar esses dados possuem grandes desafios, como volume, diversidade de informações e dinâmica dos sistemas. Entretando, um melhor entendimento sobre o processo de difusão de informação nas mídias sociais é necessário, não apenas para os usuários, mas também para empresas e pesquisadores. Exploração de propagandas, melhor organização de conteúdo e criação de novas ferramentas são exemplos de possíveis benefícios ao entender melhor o problema. Neste trabalho propomos o MIOSphere, um sistema para monitoramento, em tempo real, da propagação de informação por mídias sociais online. Além disso, foi feita uma ampla caracterização da propagação de URLs no Twitter.
