Abstract

A computer-implemented method of online collaboration on a document includes converting a source document from a document generation format to an independent file format, generating a coordinate map for displayed elements of the source document, displaying text of the document to a commenting user in the independent file format, allowing the commenting user to select and comment on the text, matching the displayed text and the comments with the source document using the coordinate map to generate a difference map, and storing the comments and the difference maps external from the source document

Claims

1. A computer-implemented method of online collaboration on a document, comprising:

converting a source document from a document generation format to an independent file format;

generating a coordinate map for displayed elements of the source document;

displaying text of the document to a commenting user in the independent file format;

allowing the commenting user to select and comment on the text;

matching the displayed text and the comments with the source document using the coordinate map to generate a difference map; and

storing the comments and the difference maps external from the source document.

2. The computer-implemented method of claim 1, further comprising providing an originating user the ability to generate the source document.

3. The computer-implemented method of claim 2, further comprising allowing the originating user to divide up the source document into sections, and the sections into doclets.

4. The computer-implemented method of claim 3, further comprising allowing the originating user to assign authors to at least one of the sections and the doclets.

5. The computer-implemented method of claim 2, wherein providing the user the ability generate the source document comprises providing the originating user a user interface through which the originating user can identify authors and commenting users for the source document.

6. The computer-implemented method of claim 1, wherein generating the coordinate map comprises generating a character-by-character map on a pixel basis.

7. The computer-implemented method of claim 1, wherein matching the displayed text and the comments comprises anchoring the comments to text in the source document.

8. The computer-implemented method of claim 1, wherein matching the displayed text and the comments with the source document using the coordinate map to generate a difference map comprises generating a difference map comprises using a longest common sequence to scan rendered content and content of the source document.

9. The computer-implemented method of claim 1, wherein generating a difference map using a longest comment sequence comprises using an extended longest common sequence in a word wise subsequence manner.

10. The computer-implemented method of claim 1, further comprising receiving a revision for the source document and implementing the revision.

11. The computer-implemented method of claim 10, wherein implementing the revision comprises:

deleting text from the source document as indicated by the revision; and

moving any comments anchored to the text to a banner associated with the document, such that the comments are displayed in the banner when the source document is displayed.

12. A system, comprising:

a first computer having a display screen, a processor, and a user input device, the processor configured to execute instructions to;

display a user interface on the display screen;

receive inputs from an originating user, the inputs identifying a source document, the inputs including identifying any portions of the source document, identification of authors and commenting users;

provide the user with an ability to create at least a portion of the source document;

generating a coordinate map of the source document; and

access a memory to allow storage of the source document, identification of authors and commenting users;

at least a second computer having a display screen, a processor and a user input device, the processor configured to execute instructions to;

access the memory to retrieve the source document and the coordinate map;

provide at least one commenting user a view of at least a portion of the source document;

receive at least one comment from the commenting user associated with text in the portion of the source document;

matching the comment with the text using the coordinate map and generating a difference map; and

storing the source document and the difference map.
