Abstract

Systems and methods for sharing annotations associated with an electronic document. The annotations are created by one or more annotation authors and are shared with one or more other users. A method includes determining frequently annotated portions of the electronic document and providing indicators within the electronic document of the frequently annotated portions. In one embodiment, frequently used words within the annotations are also indicated within the text of the electronic document. In addition, or in another embodiment, the annotations can be searched based on a user'"'"'s location within the electronic document.

Claims

1. A method of filtering electronic annotations, the method comprising:

receiving a search request comprising address information associated with a user-selected portion of an electronic document, the address information being automatically added to the search request upon a user'"'"'s selection of the user-selected portion, the address information uniquely identifying the electronic document and a location of the user-selected portion within the electronic document;

filtering a plurality of annotations to find a subset of the annotations that are associated with the user-selected portion; and

providing the subset of annotations to the user through a network.

2. The method of claim 1, further comprising filtering the subset of annotations based on how frequently the annotations in the subset are associated with a sub-portion of the user-selected portion.

3. The method of claim 1, further comprising filtering the subset of annotations based on frequently used words within the subset of annotations.

4. The method of claim 1, further comprising filtering the subset of annotations based on access rights granted to the user.

5. The method of claim 1, further comprising filtering the subset of annotations based on an identity of an author.

6. The method of claim 5, further comprising:

receiving one or more user-evaluations of an author of an annotation; and

deriving an author ranking from the one or more user-evaluations.

7. The method of claim 6, further comprising filtering the subset of annotations based on the author ranking.

8. The method of claim 1, further comprising filtering the subset of annotations based on an annotation ranking corresponding to one or more user-evaluations of the subset of annotations.

9. The method of claim 1, further comprising filtering the subset of annotations based on an annotation category.

10. The method of claim 9, wherein the annotation category corresponds to an annotation population.

11. The method of claim 1, wherein the user-selected portion of the electronic document is highlighted by the user.

12. A system accessible over a network for sharing electronic annotations of an electronic document, the system comprising:

a database for storing a plurality of user-authored annotations of the electronic document; and

a server connected to the network and configured to;

receive from a user, over the network, one or more parameters for displaying desired user-authored annotations from the database,

search the database and identify a subset of the annotations that match the received parameters, and

provide through the network the subset of annotations for display to the user.

13. The system of claim 12, wherein the received one or more parameters include at least one of location information within the electronic document, an author identifier, an annotation category, an annotation ranking, and custom search terms.

14. The system of claim 13, wherein the location information comprises a user-selection of a portion of the electronic document.
