The SavvySearch metasearch engine [34, 20] now Search.com ) combines results similarly, summing the normalized scores for each document. http: www.apple.com sherlock 28 The ProFusion metasearch engine [28, 29], in advance of receiving any queries, evaluates the performance of each search engine based on human made relevance judgments. This performance (a function of the number and ranks of relevant documents in the top ten returned) is used as a weight w i for each search engine i. Then, for each ....

....search engine. Shaw and Fox [Shaw94] used the combination of results from several different operational paradigms generated by a single engine. By summing the similarity values obtained, they demonstrated better overall accuracy than using a single similarity value. More recently, Gauch and Wang [Gauc96] developed a system, called ProFusion, that incorporates multiple parallel Web based search engines to process queries. Using a small set of queries, they evaluated results obtained by merging rankings from multiple independent parallel searches against the results of each individual engine. Their ....

Such engines include AltaVista 3 , Excite 4 , etc. Some search engines even provide a meta search capability, that is the ability to submit a query to several search engines at once. For example, PROFUSION [Gauch 96] sends user queries to multiple underlying search engines in parallel, retrieves, and merges the resulting URLs. Although these engines are a significant step towards information discovery in the cyberspace, they provide a single shot search mechanism that is in direct contrast with the ....

Examples include MetaCrawler [24] http: www.metacrawler.com) SavvySearch (http: guaraldi.cs. colostate.edu:2000 g, and ProFusion [7]. STARTS, the Stanford Protocol Proposal for Internet Retrieval and Search [9] is an emerging protocol whose goal is to facilitate the three metasearching tasks above. STARTS has been developed in a unique way. It is not a standard, but a group effort involving 11 companies and organizations, ....

The main difference among meta search engines is their techniques for selecting the search engines for a particular query and the post processing applied to the results. Three examples of meta search engines are MetaCrawler [Selberg and Etzioni 95] ProFusion [Gauch and Wang 96] and SavvySearch[Dreilinger 96] MetaCrawler [Selberg and Etzioni 95] accesses six services : Galaxy, InfoSeek, Lycos, Open Text, WebCrawler, and Yahoo. It submits the query to all six engines and merges the results. There are two optional post processing capabilities: 1) the specification of ....
