A Discriminative Kernel-based Model to Rank Images from Text Queries
This paper introduces a discriminative model for the retrieval of images from text queries. Our approach formalizes the retrieval task as a ranking problem, and introduces a learning procedure optimizing a criterion related to the ranking performance. The ...
2008Machine learning approaches to text representation using unlabeled data
With the rapid expansion in the use of computers for producing digitalized textual documents, the need of automatic systems for organizing and retrieving the information contained in large databases has become essential. In general, information retrieval s ...
EPFL2008AlvisP2P: Scalable Peer-to-Peer Text Retrieval in a Structured P2P Network
Karl Aberer, Martin Rajman, Vinh Toan Luu, Ivana Podnar, Fabius Klemm, Gleb Skobeltsyn
In this paper we present the AlvisP2P IR engine, which enables efficient retrieval with multi-keyword queries from a global document collection available in a P2P network. In such a network, each peer publishes its local index and invests a part of its loc ...
2008Learning the structure of image collections with latent aspect models
The approach to indexing an image collection depends on the type of data to organize. Satellite images are likely to be searched with latitude and longitude coordinates, medical images are often searched with an image example that serves as a visual query, ...

EPFL2007Modeling semantic aspects for cross-media image indexing
Daniel Gatica-Perez, Florent Monay Michaud
To go beyond the query-by-example paradigm in image retrieval, there is a need for semantic indexing of large image collections for intuitive text-based image search. Different models have been proposed to learn the dependencies between the visual content ...
2007Overview of JPSearch: a Standard for Image Search and Retrieval
Touradj Ebrahimi, Frédéric Dufaux, Michael Ansorge
In this paper, we review the on-going JPSearch standardization activity. Its goal is to provide a standard for interoperability for image search and retrieval systems. More specifically, JPSearch aims at defining the interfaces and protocols for data excha ...
2007Web Text Retrieval with a P2P Query-Driven Index
Karl Aberer, Martin Rajman, Vinh Toan Luu, Ivana Podnar, Gleb Skobeltsyn
In this paper, we present a query-driven indexing/retrieval strategy for efficient full text retrieval from large document collections distributed within a structured P2P network. Our indexing strategy is based on two important properties: (1) the generate ...
