This solution presents limitations when the goal is to represent how users interact with specific user interface elements, since this approach may not have detailed information about what the users do in a Web page. This technical report presents a model for logging client-side events and an implementation of it in a tool called WELFIT (Web Event Logger and Flow Identification Tool). By using the model presented here miner systems can capture more detailed Web usage data, making possible a more fine-grained examination of Web pages usage. In addition, the model can help HCI (Human-Computer Interaction) practitioners to log client-side events of mobile devices, set-top boxes, Web pages, among other artifacts. } }
