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.

Claims

1. A processor implemented method for finding documents which relate to a portion of a temporal document, comprising:

(a) initiating a signal of interest at any time during the temporal document;

(b) capturing content between the time the content is present in the temporal document and the time of initiating the signal of interest;

(c) finding the related documents based upon the content captured between the time the content is presented in the temporal document and the time of initiating the signal of interest by use of information retrieval techniques, including related documents not previously associated with the content captured; and

(d) selecting the related documents from among a collection of documents which may be accessed through the Internet, by utilizing databases comprising information about the collection;

wherein the related documents are accessed through the Internet, and wherein the related documents are selected from the collection according to the scores achieved when evaluating documents in the collection according to a formula giving scores to documents depending upon the occurrence in the documents of terms which occur in the content captured.

2. The method of claim 1, wherein the temporal document is video or audio material.

3. The method of claim 2, wherein the video material is stored on a video server.

4. The method of claim 1, wherein the temporal document includes text.

5. The method of claim 4, wherein the document text appearing to the user varies with time.

6. The method of claim 5, wherein the text includes news bulletins, weather, sports scores or stock transaction or pricing information.

7. The method of claim 1, wherein the determination of the documents in the collection which receive the highest scores is carried out using compressed document surrogates.

8. The method of claim 1, wherein the determination of the documents in the collection which receive the highest scores is carried out by a server which is distinct from the server which receives the signal of interest.

9. The method of claim 1, wherein a predetermined number of documents are selected.

10. A processor implemented method for finding documents which are accessed through the Internet and 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 portion of the temporal document present up to the time of the signal of interest for which related documents are to be found;

(b) using information retrieval techniques, selecting, from among a collection of documents which may be accessed through the Internet, related documents based on the identified portion of the temporal document present up to the time of the signal of interest, including related documents not previously associated with the identified portion of the temporal document, by utilizing databases comprising information about the collection, according to the scores achieved when evaluating documents in the collection according to a formula giving scores to documents depending upon the occurrence in the documents of terms which occur in text associated with the portion of the temporal document identified, wherein a predetermined number of documents are selected.

11. A processing device for finding documents which relate to a portion of a temporal document, comprising:

(a) means for initiating a signal of interest at any time during the temporal document;

(b) means for capturing content between the time the content is present in the temporal document and the time of initiating the signal of interest; and

(c) means for finding the related documents based upon the content captured between the time the content is presented in the temporal document and the time of initiating the signal of interest by use of information retrieval techniques, including related documents not previously associated with the content captured; and

(d) means for selecting the related documents from among a collection of documents which may be accessed through the Internet, by utilizing databases comprising information about the collection;

wherein the related documents are accessed through the Internet; and

wherein the related documents are selected from the collection according to the scores achieved when evaluating documents in the collection according to a formula giving scores to documents depending upon the occurrence in the documents of terms which occur in the content captured.

12. The device of claim 11, wherein the temporal document is video or audio material.

13. The device of claim 12, wherein the video material is stored on a video server.

14. The device of claim 11, wherein the temporal document includes text.

15. The device of claim 14, wherein the document text appearing to the user varies with time.

16. The device of claim 15, wherein the text includes news bulletins, weather, sports scores or stock transaction or pricing information.

17. The device of claim 11, wherein the determination of the documents in the collection which receive the highest scores is carried out using compressed document surrogates.

18. The device of claim 11, wherein the determination of the documents in the collection which receive the highest scores is carried out by a server which is distinct from the server which receives the signal of interest.

19. The device of claim 11, wherein a predetermined number of documents are selected.

20. A processing device for finding documents which are accessed through the Internet and relate to a portion of a temporal document, comprising:

(a) means for identifying, in response to a signal of interest at a particular time during the temporal document, a portion of the temporal document present up to the time of the signal of interest for which related documents are to be found;

(b) means for selecting, based on the identified portion of the temporal document present up to the time of the signal of interest and by use of information retrieval techniques, related documents from among a collection of documents which may be accessed through the Internet, including related documents not previously associated with the identified portion of the temporal document, by utilizing databases comprising information about the collection, according to the scores achieved when evaluating documents in the collection according to a formula giving scores to documents depending upon the occurrence in the documents of terms which occur in text associated with the portion of the temporal document identified, wherein a predetermined number of documents are selected.
