document: From user-centric web traffic data to usage data In this paper , we describe a user-centric Internet usage data processing platform . Raw usage data is collected using a software probe installed on a panel of Internet users ' workstations . It is then processed by our platform . The transformation of raw usage data into qualified and usable information by Internet usage sociology researchers means setting up a series of relatively complex processes using quite a wide variety of resources . We use a combination of ad hoc rule-based systems and external resources to qualify the visited Web pages . We also implemented topological and temporal indicators in order to describe the dynamics of Web sessions .
