Facilitating Web navigation
: While you are searching or exploring the Web, Nestor draws a web map representing the links
and documents you're visiting : you can use this map to go back directly to
any document you have visited previously ( no need to use the
"back" or "forward" buttons). The maps provide a visual
context so you always know "where you are" and "where you come
are fully customizable, you can save them and
use them as bookmark archives.Nestor is
also a "writer" tool : y
ou can enrich your Web maps with annotations, new links or new
documents (see "working with Nestor
You are truely "weaving your personal
information space". Finally
Nestor is a
collaborative tool : you can chat, surf the Web and exchange maps with other
Nestor users (see "connecting to IRC
" or "peer-to-peer work
Promoting constructivist learning
: in education,
hen the Web is used as a source of
information, Nestor maps provide a kind of "notebook" : t
eachers can ask their students to search the Web for
documents relevant to a given theme ... and ask them to provide the results as a
Nestor map : the students are encouraged to add their personal annotations, personal
texts and information structure to the maps (and not merely pure Web
resources !). Nestor philosophy is to encourage users evolve from Web readers to Web writers
, from navigation experience to abstraction
individual work to
and thus from raw information access to
knowledge construction. Nestor is intended to be used as a constructionist
Supporting the "reflective practitioner"
: a reflective practitioner uses the computer as a
reflective tool - literally a tool that reflects thinking. If you're doing
some thinking while you navigate the web (I am sure you do :):) then you
need a tool to help express your thinking. That's the idea of Nestor structuring map-objects
: they facilitate the
copy/paste/structuring of the Web information that counts for you.
Instrumenting research: Nestor is a research
prototype that can be used to investigate various aspects of Web navigation. It
records an historic file as well as navigation datas (new developments on
request). Statistics, historical and navigation maps, profiles of interest ...
can be computed from the historic file.
To summarize : Nestor maps are a
new kind of Web documents : they incorporate various objects : links,
texts, grids, images ... But while the standard html documents are designed for presenting
information, Nestor hybrid maps
are designed to facilitate knowledge construction
through re-composition of objects.

Updating : Download Nestor.exe and save it into C:\Nestor directory
(or click Nestor Help/Update menu) Latest release is Nestor - Release
Groupware : Nestor
groupware uses HTTP,FTP,SMTP,IRC and P2P protocols - server-side
software is a Microsoft IIS Web server Isapi extension that is available on
Microsoft WINDOWS plateforms ONLY - Vista excepted (sorry for Mac users)
* Even if
Nestor replaces InternetExplorer, you have to install IE because Nestor uses IE
There is a version of Nestor which runs with IE4 and another version runs
with IE5, IE6 or IE7. Check your IE version before downloading
* Nestor was NOT designed to draw maps of full web sites
(although it does it). It draws what YOU have
* Nestor has been designed for 1024x768 screen
definition (it works on 800x600 but it means more window management !).
1600x1200 is excellent !

* Facilitating knowledge
construction in Web exploration activities
July 2005 : In most information search tasks users have
to shift from a Web-experience-representation to a
Knowledge-representation. We think that Web browsers should facilitate this process -
or rather mediate it
. Let us call this process :
= progressing from experience to abstraction
through de-construction of documents
Most features in
Nestor are targeted at this: including handling multiple views
incorporating structuring objects
(such as associations, grids
and others ), allowing flexible hybrid representations
, and co-constructing
shared representations (see an
example of re-composition : http://www.projeto.org.br/hawaii/indextutorials.htm
A. Okada from Ed-Media 2003 information)
* Other improvements :
March 2006 : Nestor hybrid maps (a mix of navigation and concept maps) will
soon have NEW structuring objects : lists, page sets ....

"....The Nestor system (
a client-side tool that extends the bookmarking functionality of Microsoft's
Internet Explorer browser. It does so by graphically representing the paths that
a user takes from one page to the next, drawing links as and when they arise and
making connections where appropriate. Users may heavily customise and annotate
these maps using symbols and text, leading to what looks rather like a mind map.
A particular beauty of the system is that these maps may be shared with others
and combined, although visual annotations are lost in the process. Users can
navigate sites together and make use of a built-in IRC real-time chat client to
discuss what they find there. Not only that, but there is also a collaborative
annotation tool for sites visited, which uses FTP and/or file server protocols
to store its annotations, which are group oriented so that only those with whom
a user wishes to share annotations will see them. Although Nestor's only
significantly emergent feature is the ability to combine maps, it represents an
attitude to collaboration and virtual presence which extends the concept of
community-building far beyond the simple chat, forum and email systems which
currently dominate the available communications tools available on the
