Mertens, Robert; Ketterl, Markus; Brusilovsky, Peter – Interactive Technology and Smart Education, 2010
Purpose: Social navigation is an emerging trend for navigation in hypermedia. With social navigation, users can be guided through large volumes of learning content by cues which integrate the browsing history of past users. Earlier papers have shown that social navigation is suitable for navigation not only in classic hypermedia but also in…
