Abstract: Finding a previously visited page during a Web navigation is a very common and important kind of interaction. Although most commercial browsers incorporate history mechanisms, such mechanisms are typically very simple indexes of visited pages, sorted according to the time dimension. They are not very effective and are quite far from giving users the impression of a semantically aware, longterm memory, as it is available to the human brain. In particular they lack associative, semantic-based mechanisms that are essential for supporting information retrieval. This paper introduces the xMem (Extended Memory Navigation) as a new method to access users’ navigational history, based upon semantic-based and associative accesses. Its aim is to imitate some of the features of the human memory, so as to give users a better understanding of the context of their searches, by exploiting time-based ordering and semantic clues.
