<P>PROBLEM TO BE SOLVED: To recommend an excellent research term to advertisers managing their accounts in one or more of two ways, in a pay-for-placement search system. <P>SOLUTION: A first technique involves looking for good search terms directly on an advertiser's web site. A second technique involves comparing an advertiser to other, similar advertisers and recommending the search terms the other advertisers have chosen. The first technique is called spidering and the second technique is called collaborative filtering. In the preferred embodiment, the output of the spidering step is used as input to the collaborative filtering step. The final output of search terms from both steps is then interleaved in a natural way. <P>COPYRIGHT: (C)2003,JPO |
