We have developed a new Active Portal web page on

Science - Biology - Immunology

It has links to hundreds of pages. Please check it out! Thanks.

The address is:

This page has been developed as part of the Active Portal
Project in the Computer Science Department at the University of 
Wisconsin, an ongoing research project.

An active portal is a page devoted to a particular topic
but with a difference.

The active portal is seeded with a number of a pages known 
to be about a topic. A search agent then learns the
characteristics of those pages and then seeks out similar pages.
This search agent runs automatically and continuously. Thus the 
active portal, unlike manually-compiled portals like Yahoo, 
continually discovers new pages about a topic. In addition, 
it ranks a page based on a combined measure of its popularity
and content level.

The active portal also features a sign-up box for a mailing
list that is used to alert its members to new pages that the
search agent discovers.

Please feel free to reply to this message with any comments.

Best regards,
