Abstract

A personalized content recommendation system includes a client interface device configured to monitor a user'"'"'s information data stream. A collaborative filter remote from the client interface device generates automated predictions about the interests of the user. A database server stores personal behavioral profiles and user'"'"'s preferences based on a plurality of monitored past behaviors and an output of the collaborative user personal interest inference engine. A programmed personal content recommendation server filters items in an incoming information stream with the personal behavioral profile and identifies only those items of the incoming information stream that substantially matches the personal behavioral profile. The identified personally relevant content is then recommended to the user following some priority that may consider the similarity between the personal interest matches, the context of the user information consumption behaviors that may be shown by the user'"'"'s content consumption mode.

Claims

1. A method of providing personalized content recommendations using a computer comprising:

providing a user interface on a computing device that monitors a user'"'"'s information;

generating a content signature that includes semantically salient content elements from the monitored user'"'"'s information, a network address to the monitored user'"'"'s information that the semantically salient content is based upon, and a plurality of densities of topics embodied in the salient content elements;

storing a personal behavioral profile in a memory of the computing device, the memory stored with user'"'"'s preferences based on a plurality of monitored past behaviors and a collaborative filtering;

filtering items in an incoming information stream with the personal behavioral profile and the content signature and responsive to a document ranking based in part on a plurality of phrase inhibitors and a plurality of saturation topic phrases; and

receiving only those items of the incoming information stream that match and is responsive to the document ranking and the personal behavioral profile for a certain information consumption mode of the user.

2. The method of claim 1 where the computing device comprises a mobile computing device.

3. The method of claim 1 where the computing device comprises a non-mobile computing device.

4. The method of claim 1 further comprising displaying only those items of the incoming information stream that match the personal behavioral profile.

5. The method of claim 1 where the personal behavioral profile is based on a user event.

6. The method of claim 1 where the filtering comprises HTML filters that removes ads, navigation bars, tags, redirection links, and navigation links from the data stored in the memory.

7. The method of claim 1 further comprising extracting a content signature based on the monitored user information stream by modeling document level user'"'"'s dwell times.

8. The method of claim 1 further comprising extracting the content signature based on the monitored user information by modeling dwell times.

9. The method of claim 1 further comprising extracting a content signature in response to inferring word level user dwell times.

10. The method of claim 1 further comprising identifying consumed content at a page level through a comparison of time stamps of the user'"'"'s information stored in the memory.

11. The method of claim 1 further comprising generating snapshots by appending a time stamp to a user'"'"'s behavior record, and a file parsed from the monitored user information.

12. The method of claim 1 where the personal behavioral profile comprises an aggregation of user profiles having similar characteristics.

13. The method of claim 1 further comprising automatically detecting a shift in the personal behavioral profile and applying a second personal behavioral profile in the filtering act.

14. A method of providing personalized content recommendations using a computer comprising:

providing a user interface on a computing device that a user'"'"'s information generating a content signature that includes semantically salient content elements from the monitored user'"'"'s information, a network address to the monitored user'"'"'s information that the semantically salient content is based upon, and a plurality of densities of topics embodied in the salient content elements;

stream;

storing a personal behavioral profile in a memory of the computing device, the memory stored with user'"'"'s preferences based on a plurality of monitored past behaviors and a collaborative filtering;

filtering items in an incoming information stream with the personal behavioral profile;

and the content signature;

receiving those items of the incoming information stream that match the user'"'"'s interest profile for a certain information consumption mode of the user; and

extracting the content signature based on the monitored user information and in response to modeling concept word level dwell times.

15. A personalized content recommendation system comprising:

a client interface device configured to monitor a user'"'"'s information transmitted on a computer network;

a collaborative personal interest inference engine resident to a non-transient media and configured to generate automatic predictions about the interests of the user;

a database server stored with a personal behavioral profile and user'"'"'s preferences based on a plurality of monitored past behaviors and an output of the collaborative personal interest inference engine for a plurality of user consumption modes respectively; and

a server programmed to filter items in an incoming information stream with the personal behavioral profile and content signatures and programmed to identify only those items of the incoming information stream in response to the personal behavioral profile, the user'"'"'s preferences, and based in part on a plurality of phrase inhibitors and a plurality of saturation topic phrases;

where the content signatures include semantically salient content elements from the monitored user'"'"'s information, a network address to the monitored user'"'"'s information that the semantically salient content is based upon, and a plurality of densities of topics embodied in the salient content elements.

16. The system of claim 15 where the server assigns a priority score for each selected content designated well-matched with the personal interest of a user.

17. The system of claim 15 where the client interface device resides on a mobile computing device.

18. The system of claim 15 further comprising a display for rendering items of the incoming information stream that match one of the personal behavioral profiles of a user.

19. The system of claim 15 where the personal behavioral profile is based on a user event on a computing device.

20. The system of claim 15 further comprising a plurality of HTML filters that detects and removes ads, navigation bars, tags, redirection links, or navigation links from the user'"'"'s information data stream.

21. The system of claim 15 further comprising a remote computing platform programmed to extract a content signature based on the monitored user information stream responsive to modeling document level user'"'"'s dwell times.

22. A personalized content recommendation system comprising:

a client interface device configured to monitor a user'"'"'s information transmitted on a computer network;

a collaborative personal interest inference engine resident to a non-transient media and configured to generate automatic predictions about the interests of the user;

a database server stored with a personal behavioral profile and user'"'"'s preferences based on a plurality of monitored past behaviors and an output of the collaborate personal interest inference engine for a plurality of user consumption modes respectively;

a server programmed to filter items in an incoming information stream with the personal behavioral profile and programmed to identify only those items of the incoming information stream that matches the personal behavioral profile; and

a computing platform programmed to extract a content signature based on the monitored user information stream responsive to modeling concept word level dwell times;

where the content signatures include semantically salient content elements from the monitored user'"'"'s information, a network address to the monitored user'"'"'s information that the semantically salient content is based upon, and a plurality of densities of topics embodied in the salient content elements.
