Adaptive Knowledge-Based Visualization for Accessing Educational Examples

A number of research teams are working to organize personalized access to the modern repositories of educational resources. The goal of personalized access is to help students locate resources that match their individual goals, interests, and current knowledge. The project presented in this paper is focused on the least explored way of personalized access - adaptive visualization. Here, we present the NavEx ADVISE visualization system, which provides personalized access to a repository of educational examples. The system combines spatial, similarity-based visualization with adaptive annotations of resources. The spatial layout and the adaptive annotations are generated using a knowledge-based indexing of examples with domain concepts.
