Abstract

An electronic library which comprises a user interface such as a computer screen, a speaker, a mouse and/or a keyboard; a processor for handling communication with the user and for responding to user requests; and a data store. The data store maintains scanned segments of video data, audio data, or both, and translated replicas of the scanned segments. Searching for specific data is performed by perusing through the translated replicas, but the information that is provided to the user is primarily the scanned segments themselves. The translated versions contain the immediately translatable version of the displayable information and processed information that forms various aggregations of the displayable information. This processing imposes a syntactically logical structure on the displayable information.

Claims

1. A method for accessing a physically perceivable information segment from a plurality of physically perceivable information segments stored in a computer storage medium COMPRISING THE STEPS OF:

maintaining in said computer storage medium a digitized representation of each of said plurality of physically perceivable information segments.

maintaining in said computer storage medium at least one corresponding translated representation of each of said plurality of physically perceivable information segments,

maintaining in said computer storage medium binding information that associates elements of each translated representation of each physically perceivable information segment with portions of the corresponding digitized representation of each physically perceivable information segment, and

in response to a user request, selecting one of the physically perceivable information segments maintained in said computer storage medium, and

presenting the digitized representation of the selected physically perceivable information segment to the user.

2. The method of claim 1 wherein the step of selecting searches through the translated representation of at least some of said plurality of physically perceivable information segments and, based on the user request, selects said one of the physically perceivable information segments.

3. The method of claim 1 wherein said translated representation of an physically perceivable information segment contains elemental informational entities of said physically perceivable information segment derived from a first analysis process of the corresponding digitized representation of said physically perceivable information segment.

4. The method of claim 3 wherein said translated representation of an physically perceivable information segment further contains higher order informational entities of said physically perceivable information segment derived from an analysis process of the elemental informational entities.

5. The method of claim 4 wherein the user request specifies the presence of chosen higher order informational entities in the selected physically perceivable information segment.

6. The method of claim 4 wherein each of the translated representation is a result of a processing step that translates the corresponding digitized representation into a collection of elemental informational entities, which processing step is carried out without interactive assistance from a human for the purpose of improving the translation of the digitized representation into said collection of elemental informational entities.

7. The method of claim 6 wherein a second analysis process groups said elemental informational entities into macro-elements, based on the position of said elemental informational entities on said physically perceivable information segment relative to the position of other elemental informational entities on said physically perceivable information segment.

8. The method of claim 3 wherein said binding information correlates the elemental informational entities in the translated representation of a given physically perceivable information segment with subsegments of the digitized representation of the given physically perceivable information segment.

9. The method of claim 8 wherein said binding elemental information further correlates groups of informational entities in the translated representation of the given physically perceivable information segment with super-subsegments of the digitized representation of the given physically perceivable information segment, which groups form logical blocks within the given physically perceivable information segment.

10. The method of claim 8 wherein said binding information further correlates groups of elemental informational entities in the translated representation of the given physically perceivable information segment with super-subsegments of the digitized representation of the given physically perceivable information segment, which groups possess informational content to the user.

11. The method of claim 10 wherein the user request specifies a particular informational content in the selected physically perceivable information segment.

12. The method of claim 3 wherein the user request specifies the presence of particular elemental informational entities in the selected physically perceivable information segment.

13. The method of claim 3 wherein said elemental informational entities represent characters.

14. The method of claim 3 wherein said first analysis process includes analysis steps that recognize characters in said physically perceivable information segment.

15. The method of claim 1 wherein said physically perceivable information segments are image segments.

16. The method of claim 1 wherein said physically perceivable information segments are images of printed pages.

17. The method of claim 1 wherein said physically perceivable information segments are images of printed pages that include text and non-text material.

18. The method of claim 1 wherein said segment is an audio segment.

19. The method of claim 1 wherein each of the translated representations is a result of a processing step that translates the corresponding digitized representation into a collection of elemental informational entities, which processing step is carried out without interactive assistance from a human for the purpose of improving the translation of the digitized representation into said collection of elemental informational entities.

20. The method of claim 19 wherein said processing step

identifies digitized subsegments of said information segments that contain elemental informational entities

translates each digitized subsegment by a) identifying elemental information entities that are possibly contained in the digitized subsegment and b) with each identified elemental informational entity associating a confidence measure that the elemental informational entity is contained in the digitized subsegment, and

maintaining identified elemental informational entities that have an associated confidence measure that exceeds a preselected threshold.

21. The method of claim 1 wherein said step of presenting highlights resemblance of said user request when said resemblance is present in the digital representation of the selected physically perceivable information segment.

22. The method of claim 21 further comprising the step of requesting input from the user to confirm elements of the translated representation of each of said plurality of physically perceivable information segment.

23. The method of claim 1 further comprising the steps of

accepting user input that focuses attention to a particular portion of the presented digitized representation of the selected physically perceivable information segment, and

responding to user commands regarding the presented digitized representation of the selected physically perceivable information segment.

24. The method of claim 23 wherein said step of responding permits the user to modify elemental informational entities in the translated representation of the selected physically perceivable information segment.

25. The method of claim 23 wherein said step of responding includes a step of displaying additional information associated with the particular portion of the presented digital representation to which attention is focused by said user input.

26. A method for accessing a physically perceivable information segment from a plurality of physically perceivable information segments stored in a computer storage medium COMPRISING THE STEPS OF:

maintaining in said computer storage medium a digitized representation of each of said plurality of physically perceivable information segments,

maintaining in said computer storage medium at least one corresponding translated representation of each of said plurality of physically perceivable information segments,

maintaining in said computer storage medium binding information that associates elements of each translated representation of each physically perceivable information segment with portions of the corresponding digitized representation of each physically perceivable information segment, and

in response to a user request, identifying physically perceivable information segments maintained in the computer storage medium that comport with the user request, and

presenting to the user at least a portion of the digitized representation of an physically perceivable information segment identified in the step of identifying.

27. The method of claim 26 wherein said step of identifying accesses a pointer in a table that associates user requests with physically perceivable information segments.
