Direct Hit was swallowed by Ask Jeeves in January 2000. Today, its relevance ranking technology is used by Ask Jeeves in search services for third-party Web sites. The Jeeves folks have a separate Web search product geared directly toward consumers, Teoma, which also bears mention in this discussion. The 2-month-old search engine, at www.teoma.com, features a dynamic technique for improving relevance that's somewhat similar to what Kanisa is doing. Teoma looks at clusters of similar sites on the Web and allows users to repeatedly make fine distinctions about sites within those clusters. Start, hypothetically, with a search for ``wine,'' then ``wine producers,'' then ``Napa Valley wine producers.''
* Anyone used www.Teoma.com yet? Feedback??
