We are interested in the process which governs customer’s interface action and system response of an e-shop. We learn: to create and evaluate customer preference models based on some business models; to effectively find top-k answers; a domain calculi for these. Labs are composed of reporting on current achievements, preference learning, a project of a virtual Lean Startup and customer imitation via a social network.
