CROSS-MEDIA SIMILARITY MEASURES THROUGH TRANS-MEDIA PSEUDO-RELEVANCE FEEDBACK AND DOCUMENT RERANKING
First Claim
1. A multimedia information retrieval method performed by an electronic:
- device, the method comprising;
performing an initial information retrieval process respective to a multimedia reference repository to return a set of initial repository documents;
computing values of at least one monomodal pairwise similarity measure for candidate documents of the multimedia reference repository respective to repository documents of the set of initial repository documents; and
identifying a set of top-ranked documents of the multimedia reference repository based at least in part on the values computed for the candidate documents.

Abstract
A multimedia information retrieval system includes a storage and an electronic processing device. The latter is configured to perform a process including: computing values of a pairwise similarity measure quantifying pairwise similarity of documents of a multimedia reference repository; storing the computed values in the storage; performing an initial information retrieval process respective to the multimedia reference repository to return a set of initial repository documents; and identifying a set of top ranked documents of the multimedia reference repository based at least on the stored computed values pertaining to the set of initial repository documents.

12. A multimedia information retrieval method performed by an electronic device, the method comprising:
-
performing an initial monomodal information retrieval process operating on a first media modality to retrieve a set of initial repository documents from the multimedia reference repository; and identifying a set of top-ranked documents of the multimedia reference repository based at least in part on pairwise similarity measure values respective to a second media modality different from the first media modality for document pairs that include documents of the set of initial repository documents. - View Dependent Claims (13, 14, 15, 16, 17)

18. A multimedia information retrieval system comprising:
-
a storage; and an electronic processing device configured to perform a process including; performing an initial monomodal information retrieval process respective to a multimedia reference repository to return a set of initial repository documents, the monomodal information retrieval process operating on one member of the group consisting of text content and image content, and identifying a set of top-ranked documents of the multimedia reference repository based at least on pairwise similarity measure values indicative of similarity with documents of the set of initial repository documents, the pairwise similarity measure values being indicative of similarity respective to the other member of the group consisting of text content and image content. - View Dependent Claims (19, 20)
