document: Applying NavOptim to minimize navigational effort A major factor in the effectiveness of the interaction which users have with Web applications is the ease with which they can locate information and functionality which they are seeking . Effective design is however complicated by the multiple design purposes and diverse users which Web applications typically support . In this paper we describe a navigational design method aimed at optimising designs through minimizing navigational entropy . The approach uses a theoretical navigational depth for the various information and service components to moderate a nested hierarchical clustering of the content .
