Abstract
A method implemented on a computer for facilitating World Wide Web Searches and like database searches by combining search result documents, as provided by separate search engines in response to a query, into one single integrated list so as to produce a single document with a ranked list of pages, includes the steps of: (a) training the computer for each search engine by clustering training queries and building cluster centroids; (b) Assign weights to each cluster reflecting the number of relevant pages expected to be obtained by this search engine for queries similar to those in that cluster; (c) processing an incoming query by selecting, for each search engine, that cluster centroid that is most similar to the incoming query and returning the weight associated with the selected cluster as the weight of the current search engine; and (d) apportioning the N slots in the retrieved set according to the weights returned by each search engine.
