Avaliação do Perfil de Acesso e Navegação de Usuários em Ambientes Web de Compartilhamento de Vídeos

Recently, it has been observed an increasing popularization of vi- deo sharing environments. Part of such success is due to the change on the user perspective from content consumer to content creator, basic fundament of the Web 2.0. Thus, video service providers are dealing with different challenges such as, content storage, perfor- mance and scalability of servers, personalization, and service dif- ferentiation. In this context, it is crucial to understand the characte- ristics of requests that arrive on these servers, and the access patte rn of users on these interactive systems. This work approaches these aspects. Through the analysis of a video service workload from UOL, the largest content provider of Latin America, we present a complete characterization of user sessions, their requests to the ser- ver, and their navigation profile. Such analyses are important not only to generate synthetic workload, but also to project and create new infra-structures to video sharing systems. Our results show that there are different profiles of users and also provide a better understanding of the user access pattern to video sharing systems.
