Teoma Relaunch Now Live on the Web

[gprice]

The Much Anticipated Relaunch of Teoma is Now Live On the Web
http://www.teoma.com

What's New

Database Size (Claim 200 million pages) vs. 90-100 million prior to relaunch.
They anticipate having the database at 500 million urls by the fall.
The names of the 3 types of results have also changed:
Web Pages...Now Labeled as "Results"
Web Pages by Topic...Now Labeled as "Refine"
Expert Links...Now Labeled as "Resources"

Explanation/examples available stress that part of the ranking algorithm is 
based, on what Teoma terms, "Subject-Specific Popularity". This is 
determining the authority of a page based on other pages with the same 
subject and accomplished by page and link analysis. From the site, 
"Subject-Specific Popularity ranks a site based on the number of 
same-subject pages that reference it, not just general popularity, to 
determine a site's level of authority." This concept is based in large part 
on the Hub/Authority work of Raghavan, Kleinberg and others.

An article from Scientific American (1999) written by many members of the 
CLEVER project does an excellent job of explaining and illustrating these 
ideas.
