Abstract

Architecture that employs a search engine to unobtrusively understand the concepts (topics) and entities in which a user is interested, while simultaneously understanding the current events of the world. These concepts/entities and current events are then mapped to each other to provide a personalized experience for each user that is informative as to the latest news of interest to the user. The user interests are mapped to current events, and queries are formulated, ranked, and displayed to the user that relate to what the user may be interested in searching about new events the user would not have considered without the search engine'"'"'s assistance. The popular queries are combined with the understanding of what is being indexed in a super fresh tier to determine the current events.

Claims

1. A system, comprising:

a user understanding component that identifies user interests of a user based on concepts and entities derived from user activities;

an events understanding component that identifies events relative to a point in time;

a personalization component that automatically creates a personalized set of events relative to the point in time based on matches computed between the events and the user interests, the personalized set of events presented for user interaction; and

a microprocessor that executes computer-executable instructions associated with at least one of the user understanding component, the events understanding component, or the personalization component.

2. The system of claim 1, wherein the user understanding component identifies the user interests based on sources that include user search history, social interests, and browsing trends.

3. The system of claim 1, wherein the events understanding component identifies the events based on an index of recent events and events derived from social feeds.

4. The system of claim 1, wherein the user understanding component performs entity lookup and aggregation of user interests to output a list of entities for personalization, ranking, and selection by the personalization component.

5. The system of claim 1, wherein the personalization component performs entity aggregation and matching of entities to the events based on a list of entities related to user interests and a list of entities related to events.

6. The system of claim 1, wherein the events are most recent news events within a time span of a point in time.

7. The system of claim 1, wherein the user interests are mapped to current events, and new queries for new events are formulated and presented for recommendation to the user for user interaction.

8. The system of claim 1, wherein the events understanding component identifies popular queries of a network, obtains document results for the queries, maps words of the document results to topics, derives concepts for the topics, and stores a concept profile in association with the user.

9. A method, comprising acts of:

identifying user interests of a user based on concepts and entities derived from user activities;

identifying events relative to a point in time;

automatically creating a personalized set of events relative to the point in time based on matches computed between the events and the user interests; and

presenting the personalized set of events for user interaction.

10. The method of claim 9, further comprising generating and presenting new queries based on the personalized set of events and user interests.

11. The method of claim 9, further comprising computing importance values for the entities as related to the user and ranking the entities according to the importance values.

12. The method of claim 9, further comprising identifying the concepts and entities based on at least one of user search history, browsing activity, or social network activity.

13. The method of claim 9, further comprising enabling the user to modify the user interests and exclude concepts.

14. The method of claim 9, further comprising creating the personalized set of events based in part on correlation of popular queries as relate to an index of events that occur within a recent span of time relative to the point in time, which point in time is current time.

15. The method of claim 9, further comprising identifying social network activities and relating the activities to the entities for identifying the user interests.

16. A computer-readable medium comprising computer-executable instructions that when executed by a processor, cause the processor to perform acts of:

identifying user interests of a user based on concepts and entities derived from user activities associated with at least one of user search history, browsing activity, or social network activity;

identifying events relative to a point in time;

automatically creating a personalized set of events relative to the point in time based on matches computed between the events and the concepts and entities;

generating new queries based on the personalized set of events and user interests; and

presenting the personalized set of events and new queries for user interaction.

17. The computer-readable medium of claim 16, further comprising ranking the entities based on frequency of entity interaction and variety of the entities.

18. The computer-readable medium of claim 16, further comprising mapping the user interests to related current events, formulating new queries about other new events, and presenting the new queries about the other new events for user interaction.

19. The computer-readable medium of claim 16, further comprising indexing current events and ranking the indexed current events based on a clustering technique to determine at least one of most recent events or occurring events.

20. The computer-readable medium of claim 16, further comprising analyzing social activity of social network to determine concepts and topics to recommend.
