Abstract

A method for sharing multilayered electronic content among users of a social network within a digital education platform is provided. In one embodiment, the digital education platform allows a user to create user-generated content associated with a multilayered document and share the content with other users in an education social network. The user can specify which users to share the user-generated content and assign an access right to each of those users that may access the user-generated content. When the digital education platform receives a request to access the user-generated content from a certain user, an access right associated with that user for the user-generated content is determined and access is granted according to the access right.

Claims

1. A method for sharing user generated content in a multilayered document, the method comprising:

receiving user-generated content associated with a multilayered document created by a primary user, the multilayered document comprising a core layer and one or more additional layers, wherein the core layer comprises pages of a publication, an additional layer includes user-generated content related in subject matter and placement to content of the core layer, and wherein the additional layer is associated with two or more groups of secondary users within an educational social network that are provided distinct subsets of the user-generated content for the additional layer based on distinct access rights assigned by the primary user to their corresponding groups, secondary users within a group defined based on a shared characteristic within a context of the educational social network;

receiving a request, from a viewing user, to access the multi-layered document;

identifying a group of secondary users to which the viewing user belongs;

receiving user-defined access rights, defined by the primary user of the additional layer for the identified group; and

publishing a selected subset of the user-generated content within the additional layer for the viewing user in the multilayered document, the selected subset of the user-generated content that is published for display to the viewing user being determined in accordance with the received user-defined access rights associated with the identified group to which the viewing user belongs.

2. The method of claim 1, wherein the multilayered document is a textbook in markup language format and the additional layer comprises at least one of:

a related content layer comprising supplemental academic material related in subject matter and placement to content of the core layer, an interactive layer, and an advertising layer comprising targeted advertisements for educational resources related in subject matter and placement to content of the core layer.

3. The method of claim 1, wherein secondary users within a group are defined based on a shared characteristic reflecting a similarity in at least one of:

an academic standing, a level of academic skill, a level of academic preparation, academic interest, academic aptitude, an affiliation with an academic institution, and enrolment in an academic course.

4. The method of claim 1, wherein user-generated content comprises at least one of:

highlights, underlines, assignments, comments, notes and questions associated with pages of the multilayered document.

5. The method of claim 1, wherein the access rights for the user-generated content comprise at least one of:

read, write and re-share.

6. The method of claim 1, wherein the groups of secondary users within the educational social network comprise at least one of:

users enrolled in one of the primary user'"'"'s classes, users having common majors as the primary user, teachers, users enrolled in a same school as the primary user, and academic authors.

7. The method of claim 1, wherein the user-defined access rights defined by the primary user define a mode for sharing the user-generated content with users of the identified group, as being a selected one of:

an asynchronous mode that enables unidirectional communication of the user-generated content from the primary user to the secondary users in the identified group via the additional layer during a predefined duration of time after creation of the user-generated content by the primary user, a synchronous mode that enables unidirectional communication and synchronization of the user-generated content from the primary user to the secondary users in the identified group via the additional layer in real-time, and streaming mode of access that enables the secondary users of the identified group to interact with the primary user via the additional layer in real-time.

8. The method of claim 7, wherein the asynchronous access is time based.

9. A non-transitory computer-readable storage medium storing computer programs configured to execute on the computer processor, the computer program comprising:

receiving user-generated content associated with a multilayered document created by a primary user, the multilayered document comprising a core layer and one or more additional layers, wherein the core layer comprises pages of a publication, an additional layer includes user-generated content related in subject matter and placement to content of the core layer, and wherein the additional layer is associated with two or more groups of secondary users within an educational social network that are provided distinct subsets of the user-generated content for the additional layer based on distinct access rights assigned by the primary user to their corresponding groups, secondary users within a group defined based on a shared characteristic within a context of the educational social network;

receiving a request, from a viewing user, to access the multi-layered document;

identifying a group of secondary users to which the viewing user belongs;

receiving user-defined access rights, defined by the primary user of the additional layer for the identified group; and

publishing a selected subset of the user-generated content within the additional layer for the viewing user in the multilayered document, the selected subset of the user-generated content that is published for display to the viewing user being determined in accordance with the received user-defined access rights associated with the identified group to which the viewing user belongs.

10. The storage medium of claim 9, wherein the multilayered document is a textbook in markup language format and the additional layer comprises at least one of:

a related content layer comprising supplemental academic material related in subject matter and placement to content of the core layer, an interactive layer, and an advertising layer comprising targeted advertisements for educational resources related in subject matter and placement to content of the core layer.

11. The storage medium of claim 9, wherein secondary users within a group are defined based on a shared characteristic reflecting a similarity in at least one of:

an academic standing, a level of academic skill, a level of academic preparation, academic interest, academic aptitude, an affiliation with an academic institution, and enrolment in an academic course.

12. The storage medium of claim 9, wherein user-generated content comprises at least one of:

highlights, underlines, assignments, comments, notes and questions associated with pages of the multilayered document.

13. The storage medium of claim 9, wherein the access rights for the user-generated content comprise at least one of:

read, write and re-share.

14. The storage medium of claim 9, wherein the groups of secondary users within the educational social network comprise at least one of:

users enrolled in one of the primary user'"'"'s classes, users having common majors as the primary user, teachers, users enrolled in a same school as the primary user, and academic authors.

15. The storage medium of claim 9, wherein the user-defined access rights defined by the primary user define a mode for sharing the user-generated content with users of the identified group, as being a selected one of:

an asynchronous mode that enables unidirectional communication of the user-generated content from the primary user to the secondary users in the identified group via the additional layer during a predefined duration of time after creation of the user-generated content by the primary user, a synchronous mode that enables unidirectional communication and synchronization of the user-generated content from the primary user to the secondary users in the identified group via the additional layer in real-time, and streaming mode of access that enables the secondary users of the identified group to interact with the primary user via the additional layer in real-time.

16. The storage medium of claim 15, wherein the asynchronous access is time based.

17. A computer-implemented system for sharing user generated content in a multilayered document, the system comprising:

a computer processor; and

a non-transitory computer-readable storage medium storing computer programs configured to execute on the computer processor, the computer program comprising instructions for;

receiving user-generated content associated with a multilayered document created by a primary user, the multilayered document comprising a core layer and one or more additional layers, wherein the core layer comprises pages of a publication, an additional layer includes user-generated content related in subject matter and placement to content of the core layer, and wherein the additional layer is associated with two or more groups of secondary users within an educational social network that are provided distinct subsets of the user-generated content for the additional layer based on distinct access rights assigned by the primary user to their corresponding groups, secondary users within a group defined based on a shared characteristic within a context of the educational social network;

receiving a request, from a viewing user, to access the multi-layered document;
