Abstract

Disclosed are systems and methods for managing a browser cache offline. An example method comprises storing in a cache of a web browser on a user device information about a plurality of contents of a web page visited by a user during one or more web browsing sessions; determining logical relationships among the plurality of the contents of the web page; associating the plurality of contents of the web page with a cluster based on the determined logical relationships; receiving a request to load a web page from the web browser on the user device; upon detecting that the user device is offline, determining and detecting that the requested web page is stored in the cache and is associated with a cluster, and retrieving from the cache for off-line browsing on the user device the plurality of contents of the requested web page associated with the identified cluster.

Claims

1. A computer-implemented method for managing a browser cache to facilitate offline browsing, the method comprising:

storing in a cache of a web browser on a user device information about a plurality of contents of a web page visited by a user during one or more web browsing sessions;

determining logical relationships among the plurality of contents of the web page;

associating the plurality of contents of the web page with a cluster based on the determined logical relationships among the plurality of contents of the web page;

receiving a request to load a web page from the web browser on the user device;

upon detecting that the user device is offline, determining if the requested web page is stored in the cache and if the requested web page is associated with a cluster; and

when the requested web page is stored in the cache and associated with a cluster, retrieving from the cache for offline browsing on the user device the plurality of contents of the requested web page associated with the identified cluster.

2. The method of claim 1, further comprising associating a unique identifier with each cluster.

3. The method of claim 1, wherein the logical relationships comprise a contextual relationship among the plurality of contents of the web page.

4. The method of claim 1, wherein the logical relationships comprise a temporal relationship among the plurality of contents of the web page in connection with each respective time when each of the plurality of contents is loaded on the user device.

5. The method of claim 1, wherein the logical relationships comprise a similarity of web addresses of at least a portion of the plurality of contents of the web page.

6. The method of claim 1, wherein the logical relationships comprise an association of at least a portion of the plurality of contents of the web page with at least one web search.

7. The method of claim 1, wherein the logical relationships between the first and second portions of the plurality of contents of the web page exist when the second portion was opened from a link embedded in the first portion.

8. The method of claim 1, further comprising de-clustering one or more contents of the web page from a cluster.

9. The method of claim 8, wherein de-clustering one or more contents of the web page from a cluster includes determining whether to de-cluster a content from a cluster based on one or more of:

time of the last viewing by the user of the web page;

time spent by the user viewing the web page;

number of operations performed by the user on the web page; and

whether the clustered web page is bookmarked by the user.

10. The method of claim 1, further comprising:

receiving from the user via the web browser one or more edits to at least a portion of the displayed web page contents when the user device is offline;

associating the edited portion of the displayed web page contents with a cluster with which said web page is associated;

storing the edited portion with the displayed web page contents in the browser cache; and

when the user device is online, synchronizing the edited portion with the displayed web page contents stored in the browser cache with a remote web server.

11. A computer-based system for managing a browser cache on a user device to facilitate offline browsing, the system comprising:

a cache of a web browser configured to store on the user device information about a plurality of contents of a web page visited by a user during one or more web browsing sessions;

a logical relationship determination module configured to determine logical relationships among the plurality of contents of the web page;

a clustering module configured to associate the plurality of contents of the web page with a cluster based on the determined logical relationships among the plurality of contents of the web page;

an interface module configured to receive a request to load a web page from the web browser on the user device;

a device offline status determination module configured to detect that the user device is offline and determine if the requested web page is stored in the cache and if the requested web page is associated with a cluster; and

a retrieving module configured to retrieve from the cache for offline browsing on the user device the plurality of contents of the requested web page associated with the identified cluster when the requested web page is stored in the cache and associated with a cluster.

12. The system of claim 11, further comprising an association module configured to associate a unique identifier with each cluster.

13. The system of claim 11, wherein the logical relationships comprise a contextual relationship among the plurality of contents of the web page.

14. The system of claim 11, wherein the logical relationships comprise a temporal relationship among the plurality of contents of the web page in connection with each respective time when each of the plurality of contents is loaded on the user device.

15. The system of claim 11, wherein the logical relationships comprise a similarity of web addresses of at least a portion of the plurality of contents of the web page.

16. The system of claim 11, wherein the logical relationships comprise an association of at least a portion of the plurality of contents of the web page with at least one web search.

17. The system of claim 11, wherein the logical relationships between the first and second portions of the plurality of contents of the web page exist when the second portion was opened from a link embedded in the first portion.

18. The system of claim 11, wherein the clustering module is further configured to de-cluster one or more contents of the web page from a cluster.

19. The system of claim 18, wherein the clustering module is configured to de-cluster one or more contents of the web page from a cluster at least by determining whether to de-cluster a content from a cluster based on one or more of:

time of the last viewing by the user of the web page;

time spent by the user viewing the web page;

number of operations performed by the user on the web page; and

whether the clustered web page is bookmarked by the user.

20. The system of claim 11, further comprising:

the interface module further configured to receive from the user via the web browser one or more edits to at least a portion of the displayed web page contents when the user device is offline;

the clustering module further configured to associate the edited portion of the displayed web page contents with a cluster with which said web page is associated;

the cache further configured to store the edited portion of the displayed web page contents; and

a synchronization module configured to, when the user device is online, synchronize the edited portion of the displayed web page contents stored in the browser cache with a remote web server.

21. A computer-readable storage medium comprising computer-executable instructions for managing a browser cache on a user device to facilitate offline browsing, the instructions comprising:

storing in a cache of a web browser on a user device information about a plurality of contents of a web page visited by a user during one or more web browsing sessions;

determining logical relationships among the plurality of contents of the web page;

associating the plurality of contents of the web page with a cluster based on the determined logical relationships among the plurality of contents of the web page;

receiving a request to load a web page from the web browser on the user device;

upon detecting that the user device is offline, determining if the requested web page is stored in the cache and if the requested web page is associated with a cluster; and

when the requested web page is stored in the cache and associated with a cluster, retrieving from the cache for offline browsing on the user device the plurality of contents of the requested web page associated with the identified cluster.
