Claims (10)

A computer-implemented method for organizing and accessing information in a mixed media document system comprising:
Generating an electronic representation of the paper document;
Identifying features on the paper document and capturing a two-dimensional form of the paper document;
Identifying the location of the feature;
Indexing the features by the location and generating an index table;
Having a method. The one or more features include: extraction of text information, extraction of graphic information, execution of processes, execution of commands, arranging in a certain order, extracting video, extracting sound, storing information; creating a new document, the method of claim 1 further comprising one or more actions including at least one of displaying the and documents to print documents.   The method of claim 1, wherein identifying features on the paper document and capturing a two-dimensional form of the paper document includes identifying horizontally aligned objects and vertically aligned objects.   The method of claim 1, wherein identifying features on the paper document and capturing a two-dimensional form of the paper document includes identifying a horizontal word pair and a vertical word pair.   The step of identifying features on the paper document and capturing the two-dimensional form of the paper document is to examine the amount of vertical overlap between two successive sequences, thereby converting the sequence of text into logical lines. The method of claim 1 including the step of grouping into: Receiving the search object document; and
Creating at least a patch image of the document to be searched;
Generating one or more query terms based on the image;
Receiving one or more query terms and capturing a two-dimensional positional relationship between objects in the search target document;
Calculating at least one mixed media document and location candidates that may be responsive to the query terms based on data from the index table;
The method of claim 1 further comprising: A computer readable medium encoded with instructions, wherein the instructions, when executed on one or more processors, include a process for organizing and accessing information in a mixed media document system. Of the processor, the process
Generating an electronic representation of a paper document,
Identifying features on the paper document and capturing a two-dimensional form of the paper document;
Identifying the location of the feature;
Indexing the features by the location and generating an index table;
A computer readable medium including A computer-implemented method for accessing information in a mixed media document system, comprising:
Receiving one or more query terms and capturing a two-dimensional positional relationship between objects in the search target document;
Calculating at least one mixed media document and location candidate that may respond to the query terms based on data from an index table;
And wherein the index table indexes document features and feature locations of mixed media documents. Calculating at least one mixed media document and location candidates;
Looking up each of the one or more query terms in an index table for searching one or more locations associated with each query term;
Identifying, for each identified location, one or more candidate regions that include the location;
The method according to claim 8 , comprising: Calculating at least one mixed media document and location candidates;
Identifying one of the one or more candidate regions that best matches all of the one or more query terms;
Confirming that the one of the one or more candidate regions meets a predetermined match criterion, and determining the region as matching the search target document;
10. A method according to claim 9 , comprising:
