A novel approach to Web navigation support

•Artifacts do not serve simply to facilitate mental processes that would otherwise exist.They fundamentally shape and transform them (Vygotsky, Wertsch) :

the navigator’s subjective experience plays an important role in Webnavigation (Jul, Furnas).

Web navigation is MEDIATED by navigation software

•NESTOR approach :

help users capitalize and conceptualize their navigation experience in building navigation objects : maps, tours …

A novel approach to Web navigation support

•Any piece of information has (at least) three separate aspects :the content of the information proper the characteristics of the source, which gives context to the information.the context of use (Harper : “information that counts”)

•NESTOR approach :

help users build a personal information space highly relevantto their work context.

Combining Hypertext and graphical HCI

•Nestor provides Web navigators with multiple representations : Hypertext and Map

•Just as a hotword is contextualized in hypertext, a graphical object is contextualized into the map.

Promoting “constructive” navigation

•Nestor engage users to go beyond building maps of Web resources : they can enrich the maps in creating their own content - hypertext style.

•If Web browsing compares to reading, Nestor is more a tool for writers - or at least active readers.

•Fighting against « Web dependance » (Weir) and « plagiarism ».

21/05/2000 IRMA2000 Workshop Anchorage, Ak

Promoting collaborative Web browsing

•The key to meaningful information is a “world-known-in-common”. Technologies need to be developed that are supportive of collaboratively defined institutional matters of relevance (Harper)

•Activity - defined as action in a social context - is the framework in which information and communication are meaningful : Web browsing always takes place within a broader activity.

•Nestor incorporates a set of IRC based features that allow CSCW.

From information to knowledge with Nestor

•A three stage activity :

Individual workstep1 : gathering information into maps

step2 : incorporating personal content into the mapsstep3 : organizing information

Collaborative workstep4 : collaborating with others : joint navigation, sharing maps, tutoring.

•A “spiralling” process (Bruner)

21/05/2000 IRMA2000 Workshop Anchorage, Ak

Hands-on computers

•We have INTRANET access only (no Internet)

•You have access to a set of imported Web sites :

•Navigation is restricted to Intranet :
