3. 09. 03. 2006Interception of User's Characteristics on the Web 3 Collection of Data Modeling based upon observing the user’s actions Server side log –Full control of the server  we are sure to gain data –We can lose the time-related information – caching, back button usage Client side log –We are not sure whether the logging would be executed –detailed information about user’s actions

4. 09. 03. 2006Interception of User's Characteristics on the Web 4 Click - Client-side action recorder Using JavaScript –Standard Web technology –Asynchronous communication with server (Ajax) –Native access to the DOM Using DOM2, dynamically hooked event handlers Communication with web service on the server side –Adds semantic to the log
