         6 . The method of  claim 1 , further comprising:
 determining, based on the generated at least one signature, whether an existing multimedia content element cluster sharing a common concept with the multimedia content element can be found; and   generating another multimedia content element cluster, when it is determined that an existing multimedia content element cluster sharing a common concept with the multimedia content element cannot be found.   
     
     
         7 .

         8 . The method of  claim 1 , wherein the detected at least one clustering trigger event includes receiving a request to cluster the at least one multimedia content element, wherein the request includes at least one of: the at least one multimedia content element, at least one identifier of the at least one multimedia content element, and at least one location of the at least one multimedia content element. 
     
     
         9 . The method of  claim 1 , further comprising: storing, in a data storage, the at least one cluster including the added at least one multimedia content element, wherein each cluster is stored in a separate location of the data storage. 
     
     
         10 . The method according to  claim 1  wherein the common concept represents a sub textual information out of (a) activities or actions being performed, and (b) relationships among individuals shown in the at least one multimedia content element. 
     
     
         11 . The method according to  claim 1  wherein the common concept represents a meta aspect indicating information about an acquisition of the at least one multimedia content element. 
     
     
         12 . The method according to  claim 1  wherein the common concept represents a user having a user device that captured the at least one multimedia content element. 
     
     
         13 . The method according to  claim 1  wherein the common concept differs from a textual tag. 
     
     
         14 . The method according to  claim 1  wherein the common concept represents an item captured in the at least one multimedia content element. 
     
     
         16 . A non-transitory computer readable medium having stored thereon instructions for causing a processing circuitry to execute a process, the process comprising:
 detecting at least one clustering trigger event related to at least one multimedia content element to be clustered;   generating at least one signature for the at least one multimedia content element, each signature representing at least a portion of the at least one multimedia content element;   following the generating of the at least one signature, generating, based on the generated at least one signature, at least one tag for the at least one multimedia content element;   determining, based on the generated at least one signature, at least one multimedia content element cluster, wherein each multimedia content element cluster includes a plurality of clustered multimedia content elements sharing at least one common concept with the at least one multimedia content element; and   
       adding, to each determined cluster, the at least one multimedia content element. 
     
     
         16 . A system for clustering multimedia content, comprising:
 a processing circuitry; and   a memory, the memory containing instructions that, when executed by the processing circuitry, configure the system to:   detect at least one clustering trigger event related to at least one multimedia content element to be clustered;   generate at least one signature for the at least one multimedia content element, each signature representing at least a portion of the at least one multimedia content element;   generate, following a generating of the at least one signature, and based on the generated at least one signature, at least one tag for the at least one multimedia content element;   determine, based on the generated at least one signature, at least one multimedia content element cluster, wherein each multimedia content element cluster includes a plurality of clustered multimedia content elements sharing at least one common concept with the at least one multimedia content element; and   add, to each determined cluster, the at least one multimedia content element.
