<p>An apparatus and a method for identifying one of a plurality of documents stored in a computer-readable medium are disclosed. The method includes the steps of prompting a computer-user to construct a search expression (120), then communicating the search expression to each of a plurality of search engines located at respective World Wide Web sites. Each of the plurality of search engines is prompted to concurrently identify a respective plurality of web pages containing text consistent with the search expression and to return a respective URL for each such web page identified (130). Redundant URLs returned by the search engines are filtered to obtain an initial set of web pages. Each of the initial set of web pages is downloaded and linguistically analyzed (140) to automatically identify for the computer-user keyword phrases therein. The computer-user is prompted to construct a query expression in which one or more keyword phrases from the initial set of webpages is an operand. The query expression is then used to identify at least one web page of the initial set of web pages and the identified web page is presented to the user in the form of an abstract (150).</p> |
