RE: When Searching With Google
Google's current differentiation comes not from their ability to discern meaning or provide a user interface that is better then that of the other search engines. Instead, it is in the algorithms that figure out the 'popularity' of the page based on how many other pages (and what kind of pages) link to it. By doing this, Google effectively incorporates opinions of a large set of people. The most popular pages percolate to the top of the result list. It is the fact that the link one is looking for is right at the top of the list (as opposed to being buried on page 17), that creates the perception of higher relevancy of Google search results. I say "current" because they also experiment with other stuff, for example using certain taxonomies like the Open Directory Project index. In fact, with their recent acquisition of Applied Semantics, they seem to be very much into knowledge representation, Semantic Web approaches to search. One evidence can be seen if you search on Google for "Semantic Web". Notice that one of the adds served on the right is their own "Work at Google" advertisement. Getting back to the original question, I think the subscription search engines that contract for the quality of their results, would be more viable within the specific specialized domains as opposed to the general search areas.

Subject: RE: When Searching With Google Right. And that is why I am asking. Should the GUI give clues to the filtering? If yes, it gets harder to use. If no, its reliability vis a vis a common mental model is lowered. One should be sure what those Google numbers are saying. One should know about the phrase trade. One should understand blogging keiretsu. One should be able to set a search based on the credentials of the sources. One should be able to pick the types of credentials, not let the bot do that. Amplified acceptance of unverified assumptions is the very essence of robot wisdom. I am wondering about the viability of subscription search engines that contract for the quality of their results. len From: Michael Kay [mailto:michael.h.kay@n...] Most modern search engines give greater weight to a term the more infrequent it is in the corpus. Most also weight terms according to where and how often they appear in the source document, and some also recognize when adjacent words in the query constitute a noun phrase. What google does is anyone's guess. ----------------------------------------------------------------- The xml-dev list is sponsored by XML.org <http://www.xml.org>, an initiative of OASIS <http://www.oasis-open.org> The list archives are at http://lists.xml.org/archives/xml-dev/ To subscribe or unsubscribe from this list use the subscription manager: <http://lists.xml.org/ob/adm.pl>
