         2 . The method of  claim 1 , wherein the environmental variable includes at least one of: a time of day, location information, motion information, and weather information. 
     
     
         3 . The method of  claim 2 , wherein the at least one environmental variable is collected by at least one sensor of the computing device. 
     
     
         4 . The method of  claim 3 , wherein the at least one sensor is any one of: a camera, a web camera, a microphone, a Global Positioning System, an image analyzer, and a speech recognizer. 
     
     
         5 . The method of  claim 1 , wherein the at least one matching concept structure is fetched from at least one of: a DCC system and a data warehouse. 
     
     
         6 . The method of  claim 1 , wherein a concept structure is determined to match the at least one environmental variable when their respective signatures overlap more than a predefined threshold. 
     
     
         7 . The method of  claim 1 , wherein the at least one matching concept structure is cached for a predefined period of time set by an aging timer. 
     
     
         8 . The method of  claim 1 , further comprising:
 receiving a request to analyze an input multimedia content element;   generating metadata respective of the input multimedia content element; and   matching the at least one multimedia content element to the at least one concept structure cached in the cache memory.   
     
     
         9 . The method of  claim 1 , wherein generating metadata respective of the input multimedia content element further comprises at least one of: determining metadata associated input multimedia content element and generating metadata respective of environmental variables collected upon the receiving of the input multimedia content element. 
     
     
         10 . The method of  claim 1 , wherein a concept structure is determined to match the input multimedia content element when the generated metadata overlaps a metadata representing the concept structure. 
     
     
         11 . The method of  claim 1 , wherein the input 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, medical signals, geophysical signals, subsonic signals, supersonic signals, electromagnetic signals, and infrared signals. 
     
     
         12 . The method of  claim 1 , wherein the method is performed locally by the computing device. 
     
     
         13 . 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 . 
     
     
         14 . A system for caching concept structures in a cache memory of a user computing device, comprising:
 a processing unit; and   a memory connected to the processing unit, the memory contains instructions that when executed by the processing unit, configured the system to:   receive at least one environmental variable related to a user of the computing device;   retrieve at least one concept structure matching the at least one received environmental variable, each concept structure comprises a concept metadata associated with a plurality of multimedia content elements; and   caching the at least one matching concept structure in the cache memory.   
     
     
         15 . The system of  claim 14 , wherein the environmental variable includes at least one of: a time of day, location information, motion information, and weather information. 
     
     
         16 . The system of  claim 15 , wherein the at least one environmental variable is collected by at least one sensor of the computing device. 
     
     
         17 . The system of  claim 16 , wherein the at least one sensor is any one of: a camera, a web camera, a microphone, a Global Positioning System, an image analyzer, and a speech recognizer. 
     
     
         18 . The system of  claim 14 , wherein the at least one matching concept structure is fetched from at least one of: a DCC system and a data warehouse. 
     
     
         19 . The system of  claim 14 , wherein a concept structure is determined to match the at least one environmental variable when their respective signatures overlap more than a predefined threshold. 
     
     
         20 . The system of  claim 14 , wherein the at least one matching concept structure is cached for a predefined period of time set by an aging timer. 
     
     
         21 . The system of  claim 14 , wherein the system is further configured to:
 receive a request to analyze an input multimedia content element;   generate metadata respective of the input multimedia content element; and   match the at least one multimedia content element to the at least one concept structure cached in the cache memory.
