Synchronization and tagging of image and text data

1. A computerized method, performed by a computing system having one or more hardware computer processors and one or more non-transitory computer readable storage device storing software instructions executable by the computing system to perform the computerized method comprising:

accessing a first image-based document and a second text document, wherein each of the first and second documents include common text;

providing a user interface displaying at least a portion of the image-based document;

receiving selection from a user of a text portion of the image-based document;

receiving selection of a tag to be associated with the text portion of the image-based document;

determining an occurrence of the text portion within at least a portion of the image-based document;

searching at least a portion of the text document to identify the same occurrence of the text portion in the text document;

storing an alignment data indicating a relationship between the selected tag and both the text portion of the image-based document and the text portion of the text document; and

alternatively displaying the image-based document and the text document in the user interface responsive to user selection of a user interface control, wherein the alignment data is usable to identify the text portion in the image-based document when displayed and to identify the text portion in the text document when displayed.

2. The computerized method of claim 1 , wherein the tag indicates that the text portion is one of an object, a link to one or more existing objects, or a property of one or more existing objects.

3. The computerized method of claim 1 , wherein the at least a portion of the image-based document is the entire image-based document, a certain page of the image-based document, or a character range surrounding the text portion of the image-based document.

4. The computerized method of claim 1 , wherein the image-based document is a portable document format (PDF) document.

5. The computerized method of claim 1 , wherein the image-based document includes one or more graphical images.

6. The computerized method of claim 1 , further comprising:

receiving selection of a graphical area of the image-based document;

receiving selection of a second tag to be associated with the graphical area; and

storing alignment data indicating a second relationship between the second tag and the graphical area.

7. The computerized method of claim 6 , further comprising:

determining a second portion of the text document corresponding to a location of the graphical area of the image-based document, wherein the alignment data indicates the determined second portion of the text document.

8. The computerized method of claim 6 , further comprising:

extracting the graphical area;

formatting the graphical area as an image file; and

storing the image file.

9. The computerized method of claim 1 , further comprising:

normalizing the text portion of the image-based document by performing one or more of:

removing extra punctuation;

removing extra spaces;

removing formatting; and

removing prefixes and/or suffixes of words.

10. The computerized method of claim 1 , further comprising:

transmitting one or more properties of the tag to one or more third party databases with a request for further information.

11. The computerized method of claim 1 , wherein the tag includes one or more properties indicating the text portion or a title associated with the tag.

12. The computerized method of claim 1 , further comprising:

determining a custom model to be used in searching the text document, wherein said searching the text document is performed based on the custom model.

13. The computerized method of claim 12 , wherein the custom model is selected based on a file type of the image-based document or content of the image-based document.

14. The computerized method of claim 12 , wherein the custom model indicates keys, tags, headers, or other indicator of content in the image-based document to be used in said searching the text document.

15. The computerized method of claim 1 , further comprising:

exporting to an external computing system one or more of the tag,

data related to the tag received from one or more third-party databases; or

image files extracted from the image-based document.

16. The computerized method of claim 15 , wherein a PDF file is generated to contain the exported information.

17. A computing system comprising:

a hardware computer processor;

a non-transitory computer readable medium having software instructions stored thereon, the software instructions executable by the hardware computer processor to cause the computing system to perform operations comprising:

accessing a first image-based document and a second text document, wherein each of the first and second documents include common text;

providing a user interface displaying at least a portion of the image-based document;

receiving selection from a user of a text portion of the image-based document;

receiving selection of a tag to be associated with the text portion of the image-based document;

determining an occurrence of the text portion within at least a portion of the image-based document;

searching at least a portion of the text document to identify the same occurrence of the text portion in the text document;

storing an alignment data indicating a relationship between the selected tag and both the text portion of the image-based document and the text portion of the text document; and

alternatively displaying the image-based document and the text document in the user interface responsive to user selection of a user interface control, wherein the alignment data is usable to identify the text portion in the image-based document when displayed and to identify the text portion in the text document when displayed.

18. The computing system of claim 17 , wherein the tag indicates that the text portion is one of an object, a link to one or more existing objects, or a property of one or more existing objects.

19. The computing system of claim 17 , wherein the at least a portion of the image-based document is the entire image-based document, a certain page of the image-based document, or a character range surrounding the text portion of the image-based document.

20. The computing system of claim 17 , wherein the image-based document is a portable document format (PDF) document.
