Abstract

The apparatus and methods in accordance with the present invention include systems in the form of computer software for creating a text-searchable data structure that includes electronic image documents. The system may be configured in modules. The system converts an electronic image document into a visually optimized electronic image document and into a detail optimized electronic image document. The system also includes an OCR engine that abstracts character information from the detail optimized electronic image document and writes the character information into a text file. The visually optimized electronic image document is linked with the text file in a data structure by the system. The resulting data structure, which may be an image over hidden text pdf document, may be searched using various text based search techniques. When specified text is located in a text file, the corresponding visually optimized electronic image document may then be presented to the searcher. The present invention also provides methods for creating a text searchable data structure containing electronic image documents. The method includes providing an electronic image document, generating a visually optimized electronic image document from the electronic image document, generating a detail optimized electronic image document from the electronic image document, using an optical character recognition engine to create a text file from the detail optimized electronic image document, and linking the visually optimized image with the text file in a data structure. The method may further include writing metadata to a metadata record in the data structure, and linking the metadata record with the text file and the visually optimized electronic image document in the data structure.

Claims

1. An apparatus in the form of a computer program for creating a text searchable data structure containing electronic image documents, comprising:

a module that converts an electronic image document into a visually optimized electronic image document;

a module that converts an electronic image document into a detail optimized electronic image document;

an OCR engine that abstracts character information from the detail optimized electronic image document and writes the character information into a text file; and

,

a module that links the visually optimized electronic image document with the text file in a data structure.

2. The apparatus of claim 1, further comprising a data structure configured as a unitary data structure.

3. The apparatus of claim 1, further comprising a data structure configured as an image over hidden text pdf.

4. The apparatus of claim 1, further comprising:

a module that writes metadata to a metadata record in the data structure, the metadata record linked with the text file and the metadata record linked with the visually optimized electronic image document in the data structure.

5. The apparatus of claim 1, further comprising:

a module that searches the text file for occurrences of tagged text, and writes the occurrences of tagged text to a metadata record in the data structure.

6. A data structure comprising:

one or more visually optimized digital images; and

,

one or more text files, each text file linked with the visually optimized digital image.

7. The data structure of claim 6, further comprising:

One or more metadata records, each metadata record linked with the visually optimized digital image and each metadata record link with the text file.

8. The data structure of claim 6, further comprising:

tagged text.

9. A method for creating a text searchable data structure containing electronic image documents, comprising:

providing an electronic image document;

generating a visually optimized electronic image document from the electronic image document;

generating a detail optimized electronic image document from the electronic image document;

using an optical character recognition engine to create a text file from the detail optimized electronic image document; and

linking the visually optimized image with the text file in a data structure.

10. The method of claim 9, wherein the data structure may be unitary.

11. The method of claim 9, wherein the data structure is an image over hidden text pdf document, the image over hidden text pdf document with the visually optimized electronic image document in one layer and the text file in one layer.

12. The method of claim 9, further comprising:

writing metadata to a metadata record in the data structure; and

linking the metadata record with the text file and the visually optimized electronic image document in the data structure.

13. The method of claim 9, wherein the data structure is an image over hidden text pdf document.

14. The method of claim 9, further comprising:

identifying occurrences of tagged text in the text file; and

,

writing the occurrences of tagged text to a metadata record in the data structure.
