Where have you been from here? Trials in hypertext systems
Siegfried Reich, Leslie Alan Carr, David De Roure, Wendy Hall · ACM Computing Surveys · 1999
People are confronted with ever growing amounts of information.This makes it increasingly difficult to navigate vast information spaces in order to find appropriate information.User trails provide a mechanism that allows people not only to better manage their personal information spaces but also to ask questions such as "where do other people go from here?","what else should I read?" or "how did we come to that conclusion?".The fact that trails are built with information about the users' browsing paths and activities makes them well suited for collaborative applications where users with similar interests are to be matched.
