Method and apparatus for content representation and retrieval in concept model space
First Claim
1. A method for generating at least one model vector for representing a multimedia document comprising the steps of:
- applying a plurality of concept detectors to the multimedia document, scoring said multimedia document with respect to each detector; and
mapping said scores to a multidimensional space to produce at least one vector representation.

Abstract
A method and apparatus for extracting a model vector representation from multimedia documents. A model vector provides a multidimensional representation of the confidence with which multimedia documents belong to a set of categories or with which a set of semantic concepts relate to the documents. A model vector can be associated with multimedia documents to provide an index of its content or categorization and can be used for comparing, searching, classifying, or clustering multimedia documents. A model vector can be used for purposes of information discovery, personalizing multimedia content, and querying a multimedia information repository.
