Hypervideo: information retrieval using time-related multimedia
First Claim
1. A computer-implemented method comprising:
- receiving, through operation of said computer, an indication of interest at a particular time during display of a temporal document including at least one of audio material and video material;
in response to receiving the indication, identifying through operation of said computer, a portion of the temporal document for which related documents are to be found;
determining, through operation of said computer, text associated with the portion of the temporal document identified;
weighting, through operation of said computer each term in the determined text according to the time at which the term occurs relative to the time at which the indication of interest occurs;
initiating, through operation of said computer, a search to retrieve the related documents by use of information retrieval, techniques as applied to the weighted terms.

Abstract
Disclosed is a method and device for selecting documents, such as Web pages or sites, for presentation to a user, in response to a user expression of interest, during the course of presentation to the user of a document, such as a video or audio selection, whose content varies with time. The method takes advantage of information retrieval techniques to select documents related to the portion of the temporal document in which the user has expressed interest. The method generates the search query to use to select documents by reference to text associated with the portion of the temporal document in which the user has expressed interest, as by using the closed caption test associated with the video, or by using speech recognition techniques. The method further uses a weighting function to weigh the terms used in the search query, depending on their temporal relationship to the user expression of interest.

- Selecting, through operation of said computer, a temporal document to display, the temporal document including at least one of audio material and video material;
displaying, through operation of said computer, the temporal document; indicating, through operation of said computer, inerest in obtaining related documents at a particular time during of the temporal document; providing, through operation of said computer, the indication of interest to a system configured to identify a portion of the temporal document for which the related documents are to be found, determine text associated with the portion of the temporal document identified, weight each term in the determined text according to the time at which the term occurs relative to the time at which the indication of interest occurs, and retrieve the related documents by use of information retrieval techniques as applied to the weighted terms; and receiving, through operation of said computer, the related documents. - View Dependent Claims (15)
