Application ID: 14509558

Base Claim:
1. A method for generating concept structures from signature reduced clusters (SRCs), comprising: retrieving at least one current SRC including a cluster of signatures respective of a plurality of multimedia data elements (MMDEs); generating at least one metadata for each signature of the cluster of signatures; identifying a number of repetitions of a metadata of the at least one generated metadata; determining whether the number of repetitions of the metadata of the at least one generated metadata, within the at least one current retrieved SRC, exceeds a predefined repetition threshold; upon determining that the number of repetitions of the metadata exceeds the predefined repetition threshold, identifying the at least one metadata as representative of the SRC; comparing the representative metadata of the current retrieved SRC to metadata that is representative of at least one previously generated SRC to determine a metadata match; and upon determining that the metadata match, identifying the current retrieved SRC and the matching previously generated SRC as a concept structure, wherein the concept structure is represented by the representative matching metadata from both the current retrieved SRC and the at least one previously generated SRC.

Claim 3:
3. The method of claim 1 , wherein determining the metadata match further comprises: determining whether at least one representative metadata is identical to at least one metadata that is representative of the at least one previously generated SRC; comparing at least one signature of the SRC to at least one signature of the previously generated SRC; determining a number of signatures of the SRC that match at least one signature of the previously generated SRC; determining whether the number of matching signatures of the SRC exceeds a predefined signature matching threshold; and determining a metadata match upon at least one of: determining that at least one representative metadata is identical to at least one metadata that is representative of the at least one previously generated SRC, and determining that the number of matching signatures of the SRC exceeds a predefined signature matching threshold.
