1. A method for populating a concept database based on a plurality of multimedia data elements (MMDEs) and at least one user identifier, the concept database including a plurality of concept structures, comprising:

  • clustering a plurality of signatures of the plurality of MMDEs into a cluster of signatures;

    reducing the number of signatures in the cluster to create a signature reduced cluster (SRC);

    generating, based on the SRC and the plurality of concept structures, an index, wherein the index maps the plurality of MMDEs to a matching concept structure of the plurality of concept structures;

    associating the index with a user based on the at least one user identifier;

    storing the index and the plurality of MMDEs in the concept database;

    finding a first SRC and a second SRC that are associated to each other;

    wherein the finding comprises determining that the first SRC is associated with the second SRC based on (a) a partial match between metadata associated with first SRC and metadata associated with the second SRC, and (b) a partial match between one or more signatures of the first SRC and one or more signatures of the second SRC; and

    associating, with the second SRC, metadata related to the first SRC.
