Abstract

Methods, apparatus and articles of manufacture therefor, are disclosed for annotating documents in a viewer. In one embodiment, the method includes: associating the document with a user; identifying one or more sub-document elements in the document; augmenting the document by making words within the document selectable; displaying the augmented document in the viewer; and responsive to each user input selecting a word in the document displayed in the viewer, further augmenting the document displayed in the viewer by inserting the selected word following the sub-document element from which the word was selected.

Claims

1. A method for annotating a document in a viewer, comprising:

associating the document with a user;

identifying one or more sub-document elements in the document;

augmenting the document by making words within the document selectable;

displaying the augmented document in the viewer; and

responsive to each user input selecting a word in the document displayed in the viewer, further augmenting the document displayed in the viewer by inserting the selected word following the sub-document element from which the word was selected.

2. The method according to claim 1, wherein said augmenting further comprises inserting the selected word in a tagging comment field.

3. The method according to claim 2, wherein said augmenting further comprises making in a list one or more of frequently and recently used keywords in the document selectable.

4. The method according to claim 2, wherein said augmenting further comprises inserting a user name label of the user associated with the document after the sub-document element and before the tagging comment field.

5. The method according to claim 1, wherein each word is made selectable using a bounding box.

6. The method according to claim 5, wherein the bounding box includes a plurality of words.

7. The method according to claim 1, wherein the document is a web page.

8. The method according to claim 1, further comprising:

computing a similarity measure for identified sub-document elements; and

storing in a database a record that associates the user with the computed similarity measure of the sub-document element'"'"'s content and the selected words that follow the user name label.

9. The method according to claim 8, further comprising:

storing with the record a URL of the document;

wherein said augmenting further comprises augmenting the located sub-document elements of the document with annotations of those annotated sub-document elements stored in the record that have comparable similarity measures.

10. The method according to claim 8, further comprising displaying the selected word following the sub-document element with a different appearance from the sub-document element.

11. The method according to claim 8, wherein the similarity measure is a unique identifier that uniquely identifies sub-document elements.

12. The method according to claim 1, wherein the one or more sub-document elements are a type selected from the group consisting of words, images, phrases, sentences, paragraphs, pages, sections, and chapters.

13. The method according to claim 1, wherein the sub-document elements are a plurality of types selected from the group consisting of words, images, phrases, sentences, paragraphs, pages, sections, and chapters.

14. A method for annotating a document in a viewer, comprising:

associating the document with a user;

identifying one or more sub-document elements in the document;

augmenting the document by inserting a tagging comment field after identified sub-document elements;

displaying the augmented document in the viewer; and

responsive to each user input selecting a word in the document displayed in the viewer, further augmenting the document displayed in the viewer by inserting the selected word in the tagging comment field corresponding to the sub-document element from which the word was selected.

15. The method according to claim 14, wherein said augmenting further comprises inserting a user name label of the user associated with the document after the sub-document element and before the tagging comment field.

16. The method according to claim 15, further comprising;

computing a similarity measure for identified sub-document elements; and

storing in a database a record that associates the user with the computed similarity measure of the sub-document element'"'"'s content and the selected words that follow the user name label.

17. The method according to claim 16, further comprising storing with the record a URL of the document.

18. The method according to claim 16, wherein the similarity measure is a unique identifier that uniquely identifies sub-document elements.

19. The method according to claim 14, wherein the sub-document element is a paragraph.

20. The method according to claim 14, wherein said augmenting further comprises augmenting the document by making each word within the document selectable using a bounding box.

21. The method according to claim 20, wherein said augmenting further comprises making in a list one or more of frequently and recently used keywords in the document selectable.

22. A method for annotating a document in a viewer, comprising:

identifying one or more sub-document elements in the document;

computing a unique identifier for identified sub-document elements in the document;

augmenting the located sub-document elements of the document with annotations associated with sub-document elements stored in a database that have comparable unique identifiers;

displaying the augmented document in the viewer; and

responsive to each user input selecting a word in a document displayed in a viewer, recording in the database the selected word and the computed unique identifier of the sub-document element from which the word was selected.
