Abstract

An apparatus for providing an improved caching architecture is provided. The apparatus may include a processing element configured to cache data in clusters based on respective features, receive an indication of data desired by a user, the indication further including a particular feature, search in a cluster corresponding to the particular feature, and stream, to the user, one or more candidate results corresponding to the received indication and the particular feature.

Claims

1. A method comprising:

caching data in clusters based on respective features;

receiving an indication of data desired by a user, the indication further including a particular feature;

searching in a cluster corresponding to the particular feature; and

streaming, to the user, one or more candidate results corresponding to the received indication and the particular feature.

2. The method of claim 1, wherein caching data in clusters based on respective features comprises caching data in clusters based on location or time and wherein the indication includes location-based information or time-based information.

3. The method of claim 2, wherein caching data further comprises caching location based data as set-associative and caching time based data as direct-mapped.

4. The method of claim 1, wherein caching data further comprises clustering of the data in the background.

5. The method of claim 1, wherein streaming the candidate results to the user further comprises streaming at a variable throughput depending on a connection quality of a communication connection to the user.

6. The method of claim 1, wherein streaming the candidate results to the user further comprises streaming at a variable throughput depending on a rate of movement of the user.

7. The method of claim 1, wherein streaming the candidate results to the user further comprises streaming results based on a computed probability such that the results may include data not explicitly requested.

8. The method of claim 1, wherein caching data in clusters based on respective features comprises merging data having a first feature into a first cluster and merging data having a second feature into a second cluster.

9. A computer program product comprising at least one computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

a first executable portion for caching data in clusters based on respective features;

a second executable portion for receiving an indication of data desired by a user, the indication further including a particular feature;

a third executable portion for searching in a cluster corresponding to the particular feature; and

a fourth executable portion for streaming, to the user, one or more candidate results corresponding to the received indication and the particular feature.

10. The computer program product of claim 9, wherein the first executable portion includes instructions for caching data in clusters based on location or time and wherein the indication includes location-based information or time-based information.

11. The computer program product of claim 10, wherein the first executable portion includes instructions for caching location based data as set-associative and caching time based data as direct-mapped.

12. The computer program product of claim 9, wherein the first executable portion includes instructions for clustering of the data in the background.

13. The computer program product of claim 9, wherein the fourth executable portion includes instructions for streaming at a variable throughput depending on a connection quality of a communication connection to the user.

14. The computer program product of claim 9, wherein the fourth executable portion includes instructions for streaming at a variable throughput depending on a rate of movement of the user.

15. The computer program product of claim 9, wherein the fourth executable portion includes instructions for streaming results based on a computed probability such that the results may include data not explicitly requested.

16. An apparatus comprising a processing element configured to:

cache data in clusters based on respective features;

receive an indication of data desired by a user, the indication further including a particular feature;

search in a cluster corresponding to the particular feature; and

stream, to the user, one or more candidate results corresponding to the received indication and the particular feature.

17. The apparatus of claim 16, wherein the processing element is further configured to cache data in clusters based on location or time, and wherein the indication includes location-based information or time-based information.

18. The apparatus of claim 17, wherein the processing element is further configured to cache location based data as set-associative and cache time based data as direct-mapped.

19. The apparatus of claim 16, wherein the processing element is further configured to cluster the data in the background.

20. The apparatus of claim 16, wherein the processing element is further configured to stream at a variable throughput depending on a connection quality of a communication connection to the user.

21. The apparatus of claim 16, wherein the processing element is further configured to stream at a variable throughput depending on a rate of movement of the user.

22. The apparatus of claim 16, wherein the processing element is further configured to stream results based on a computed probability such that the results may include data not explicitly requested.

23. The apparatus of claim 16, wherein the processing element is further configured to merge data having a first feature into a first cluster and merging data having a second feature into a second cluster.

24. An apparatus comprising:

means for caching data in clusters based on respective features;

means for receiving an indication of data desired by a user, the indication further including a particular feature;

means for searching in a cluster corresponding to the particular feature; and

means for streaming, to the user, one or more candidate results corresponding to the received indication and the particular feature.

25. The apparatus of claim 24, wherein means for caching data in clusters based on respective features comprises means for caching data in clusters based on location or time and wherein the indication includes location-based information or time-based information.
