VIEW PDF: A FCA STRATEGY FOR IMPROVING WEB-BASED LEARNING SITES
Nowadays, online educational systems show a rapid development due to the growth of the Internet, which offer unique opportunities to improve them based on users’ experiences. This paper presents advances of a Formal Concept Analysis (FCA) based strategy for improving web-based learning sites. We have used together Web Usage Mining and Formal Concept Analysis techniques in order to create a visual overview of exploring web-logs and discover knowledge in web logs. We have focused on visualizing triadic data in order to emphasize user dynamics through the educational systems. Switching from a triadic to a polyadic perspective we have detected repetitive browsing habits. From all the revealed behaviors we distill then users life tracks by using Temporal Concept Analysis.
