Abstract

User activity streams are used to automatically learn associations between logical objects and form logical groups. Search results are sorted based upon their relevance to current user activity. Combined with a graphical user interface component and object database, the invention automatically retrieves and display groups and objects related to the active object.

Claims

1. A method by which one or more computer systems learn associations between logical objects based upon user activity, comprising:

tracking a history of user activity upon logical objects;

forming correlations or association values between various logical objects; and

ranking the correlations using a scoring algorithm to provide an indication of how likely it is that two logical objects are coupled or related;

wherein logical objects are various files or web pages accessed by one or more computers, such as media, text, e-mails and data files, wherein user activity upon logical objects includes activation and deactivation of logical objects, wherein activation of a logical object includes opening, browsing to, editing, and/or executing the logical object, and wherein deactivation includes closing, minimizing, deleting and/or halting the logical object.

2. The method of claim 1, wherein the correlation between logical objects is calculated based on temporal proximity between activation and deactivation of logical objects.

3. The method of claim 1, further comprising:

activating associated logical objects in response to activation of a logical object.

4. The method of claim 1, further comprising:

presenting on a display associated logical objects in response to activation of a logical object.

5. The method of claim 1, wherein when a first logical object is activated and a second logical object is subsequently activated, a strong correlation is formed between the first logical object and the second logical object.

6. The method of claim 1, wherein when a first logical object is activated and a second logical object is subsequently deactivated, a weak negative correlation is formed between the first logical object and the second logical object.

7. The method of claim 1, wherein when a first logical object is deactivated and a second logical object is subsequently activated, a strong negative correlation is formed between the first logical object and the second logical object.

8. The method of claim 1, wherein when a first logical object is deactivated and a second logical object is subsequently deactivated, a weak correlation is formed between the first logical object and the second logical object.

9. The method of claim 1, wherein a given set of logical objects, such as from a keyword-based search, is sorted by sorting the correlation strengths between the logical objects in the set and logical objects most recent in the tracked activation and deactivation history.

10. The method of claim 1, wherein logical objects are organized and operated on in groups.

11. The method of claim 10, further comprising:

periodically reevaluating the association values of logical objects within a group to determine whether the logical objects should remain in the group.

12. The method of claim 10, further comprising:

evaluating the association value of a logical object not within a group to determine if it should be included in the group.

13. A computer-implemented system configured to learn associations between logical objects based upon user activity, comprising:

means for tracking a history of user activity upon logical objects;

means for forming correlations or association values between various logical objects; and

means for ranking the correlations using a scoring algorithm to provide an indication of how likely it is that two logical objects are coupled or related;

wherein logical objects are various files or web pages accessed by one or more computers, such as media, text, e-mails and data files, wherein user activity upon logical objects includes activation and deactivation of logical objects, wherein activation of a logical object includes opening, browsing to, editing, and/or executing the logical object, and wherein deactivation includes closing, minimizing, deleting and/or halting the logical object.

14. The system of claim 13, wherein the correlation between logical objects is calculated based on temporal proximity between activation and deactivation of logical objects.

15. The system of claim 13, further comprising:

means for activating associated logical objects in response to activation of a logical object.

16. The method of claim 13, further comprising:

means for presenting on a display associated logical objects in response to activation of a logical object.

17. The system of claim 13, wherein logical objects are organized and operated on in groups.

18. The system of claim 17, further comprising:

periodically reevaluating the association values of logical objects within a group to determine whether the logical objects should remain in the group.

19. The system of claim 17, further comprising:

evaluating the association value of a logical object not within a group to determine if it should be included in the group.

20. The system of claim 13, wherein the means for tracking the history of user activity upon logical objects are located on remote devices on a communications network and transmit user activity information to a central device on said communications network, said central device containing the means for forming correlations or association values between various logical objects and the means for ranking the correlations using a scoring algorithm to provide an indication of how likely it is that two logical objects are coupled or related.
