Abstract

A method for tagging multimedia content elements is provided. The method comprises receiving at least one multimedia content element from a user device; generating at least one signature for the at least one multimedia content element; generating at least one tag based on the least one generated signature, wherein the at least one tag is searchable by the user device; and sending the tag generated for the received multimedia content element to storage on the user device.

Claims

1. A method for tagging multimedia content elements, comprising:

receiving at least one multimedia content element from a user device;

generating at least one signature for the at least one multimedia content element;

generating at least one tag based on the least one generated signature, wherein the at least one tag is searchable by the user device; and

sending the tag generated for the received multimedia content element to storage on the user device.

2. The method of claim 1, wherein the at least one multimedia content element is at least one of:

an image, graphics, a video stream, a video clip, an audio stream, an audio clip, a video frame, a photograph, images of signals, and portions thereof.

3. The method of claim 1, further comprising:

searching a data warehouse for at least one multimedia content element similar to the at least one received multimedia content element from the user device, wherein an identification of the similar signature is performed based on the at least one signature generated for the received multimedia content element and a signature of the multimedia content element stored in the data warehouse;

extracting at least one tag associated with the at least one similar multimedia content element; and

assigning the at least one extracted tag to the at least one multimedia content element received from the user device.

4. The method of claim 1, further comprising providing a most descriptive tag based on the at least one extracted tag by performing any one of:

correlating between the at least one extracted tag; and

selecting a tag associated with the at least one similar multimedia content element such that its respective signature matches the at least one multimedia content element received from the user device over a predefined threshold.

5. The method of claim 1, wherein the generation of the at least one tag is based on at least one concept structure.

6. The method of claim 5, further comprising:

querying a deep-content-classification (DCC) system to find a match between at least one concept structure and the received multimedia content element;

utilizing metadata associated with the at least one matching concept structure as the at least one tag.

7. The method of claim 6, further comprising:

providing the most descriptive tag based on the at least one extracted tag by correlation of matching concept structures.

8. The method of claim 1, wherein the generation of the at least one signature is made for at least one portion of the at least one multimedia content element.

9. A non-transitory computer readable medium having stored thereon instructions for causing one or more processing units to execute the method according to claim 1.

10. A system for tagging multimedia content elements, comprising:

a network interface for allowing connectivity to at least one user device and for receiving at least one multimedia content element from a user device;

a processor; and

a memory connected to the processor, the memory contains instructions that when executed by the processor, configure the system to;

generate at least one signature for the at least one multimedia content element;

generate at least one tag based on the at least one generated signature, wherein the at least one tag is searchable by the user device; and

send the tag generated for the received multimedia content element to storage on the user device.

11. The system of claim 10, wherein the at least one multimedia content element is at least one of:

an image, graphics, a video stream, a video clip, an audio stream, an audio clip, a video frame, a photograph, images of signals, and portions thereof.

12. The system of claim 11, wherein the system is further configured to:

search a data warehouse for at least one multimedia content element similar to the at least one received multimedia content element from the user device, wherein an identification of the similar signature is performed based on the at least one signature generated for the received multimedia content element and a signature of the multimedia content element stored in the data warehouse; and

extract at least one tag associated with the at least one similar multimedia content element; and

assign the at least one extracted tag to the at least one multimedia content element received from the user device.

13. The system of claim 11, wherein the system is further configured to provide a most descriptive tag based on the at least one extracted tag.

14. The system of claim 10, wherein the system is further configured to perform any one of:

correlate between the at least one extracted tag; and

select a tag associated with the at least one similar multimedia content element such that its respective signature matches the at least one multimedia content element received from the user device over a predefined threshold.

15. The system of claim 10, wherein the generation of the at least one tag is based on at least one concept structure.

16. The system of claim 10, wherein the system is configured to query a deep-content-classification (DCC) system to find a match between at least one concept structure and the received multimedia content element and utilize metadata associated with the at least one matching concept structure as the at least one tag.

17. The system of claim 16, wherein the system is further configured to correlate matching concept structures to provide a most descriptive tag based on the at least one extracted tag.

18. The system of claim 17, wherein the DCC system is communicatively connected to the system or included in the system.

19. The system of claim 10, wherein the generation of the at least one signature is made by a signature generator, wherein the at least one signature is generated for at least one portion of the at least one multimedia content element.
