First Claim
1. A method for finding documents which relate to a portion of a temporal document, comprising:
- (a) in response to a signal of interest at a particular time during the temporal document, identifying a temporal range of the temporal document for which related documents are to be found, the signal of interest indicating interest in a sequence of material presented over the temporal range;
(b) selecting text associated with the sequence of material presented over the temporal range of the temporal document;
(c) finding the related documents by use of information retrieval techniques as applied to the selected text,wherein the related documents are selected from a collection of documents according to scores associated with the documents, said scores for each document based on a summation of term scores for at least a subset of the terms of the selected text, the term score of a term is weighted according to a temporal position of the term within the temporal range.

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.
