Context-based analysis of multimedia content items using signatures of multimedia elements and matching concepts
First Claim
1. A method for analyzing multimedia content items, comprising:
- receiving a multimedia content item;
extracting from the multimedia content item a plurality of multimedia elements;
generating at least one signature for each of the plurality of multimedia elements;
querying a deep-content-classification (DCC) system to identify at least one concept that matches at least one of the plurality of multimedia elements, wherein querying is performed using the at least one signature generated for the multimedia elements and wherein a multimedia element is unidentified when the multimedia element does not have a matching concept identified via the querying;
generating a context for the multimedia content item using matching concepts; and
characterizing each unidentified multimedia element using the generated context and signatures of the identified at least one concept.

Abstract
A method and server for analyzing a multimedia content item are provided. The method comprises receiving a multimedia content item; extracting from the multimedia content item a plurality of multimedia elements; generating at least one signature for each of the plurality of multimedia elements; for each of the plurality of multimedia elements, querying a deep-content-classification (DCC) system to identify at least one concept that matches one of the plurality of multimedia elements, wherein querying is performed using the at least one signature generated for the multimedia elements and wherein an unidentified multimedia content element does not have a matching concept; generating a context for the multimedia content item using matching concepts; and characterizing each unidentified multimedia element using the generating context and signatures of the matching concepts.

13. A server for analyzing a multimedia content item, comprising:
-
an interface to a network for receiving a multimedia content item; a processor; and a memory connected to the processor, the memory contains instructions that when executed by the processor, configure the server to; extract from the multimedia content item a plurality of multimedia elements; generate at least one signature for each of the plurality of multimedia elements; query a deep-content-classification (DCC) system to identify at least one concept that matches at least one of the plurality of multimedia content elements, wherein querying is performed using the at least one signature generated for the multimedia elements and wherein a multimedia element is unidentified when the multimedia element does not have a matching concept identified via the query; generate a context for the multimedia content item using the matching concepts; and characterize each unidentified multimedia element using the generated context and signatures of the identified at least one concept. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
