Abstract

A computer-implemented method and apparatus for composing a composite document on a selected topic from a plurality of information sources by searching the plurality of information sources and identifying, displaying and copying files corresponding to the selected topic. A plurality of records, each of which is representative of at least one information file, are stored in a database. A single search query corresponding to the search topic is received. The database is searched in accordance with the single search query to identify records related to the single search query. A search result list is then generated having entries representative of information files identified during the database search, and the search result list is displayed in a first display window open on a user display. Signals representative of at least first and second selected entries from the search result list are received from the user, the first and second selected entries respectively corresponding to first and second information files. A second display window for displaying at least a portion of the first information file is opened on the user display, a third display window for displaying at least a portion of the second information file is opened on the user display, and a document composition window for receiving portions of the and second first information files is opened on the user display. The composite document is then composed by copying portions of the first and second information files from the second and third display windows, respectively, to the document composition window.

5. The method of claim 1, wherein step (H) comprises the steps of:

(i) copying said portion of said first information file from said second display window to a clipboard window and copying said portion of said second information file from said third display window to said clipboard window; and

(ii) composing said composite document by copying said portion of said first information file from said clipboard window to said document composition window and copying said portion of said second information file from said clipboard window to said document composition window.

6. The method of claim 1, wherein step (D) further comprises the step of forming said relevance ordered search result list by ordering said entries in said relevance ordered search result list in accordance with said relevance scores such that an entry with a highest relevance score represents a first entry on said relevance ordered search result list.

7. The method of claim 6, wherein said multi-media records identified in step (C) include files representing still images.

8. The method of claim 7, wherein said multi-media records identified in step (C) further include files representing sequences of motion video frames, and files representing sequences of digital audio frames.
