Web Search--Teoma The Much Anticipated Relaunch of Teoma is Now Live On the Web 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. Other Changes

Source: Information Today NewsBreaks "Gale Group, Dialog Announce Library Marketing Alliance"
From Barbara Quint's article, "Two Thomson Corp. subsidiaries, Gale Group (http://www.gale.com) and Dialog Corp. (http://www.dialog.com), have announced that they will begin a comprehensive, long-term joint-marketing effort designed to reach the academic and public library markets worldwide. No specific products or services were described in the announcement, beyond the fact that the first set of offerings would target the public library market and appear by the middle of this year. (This probably means timing the new products� releases for ALA�s Annual Conference.) The new alliance could put Dialog back in the public library market after decades of disinterest, as well as increase the company�s presence in academic libraries. Gale would be able to draw on Dialog�s breadth of content to round out and distinguish its offerings in these hotly contested market sectors."
