Research Field

Handling multiple points of view in a multimedia data warehouse

ACM Transactions on Multimedia Computing Communications and Applications (2006)

Anne-Muriel Arigon Anne Tchounikine Maryvonne Miquel

Data warehouses are dedicated to collecting heterogeneous and distributed data in order to perform decision analysis. Based on multidimensional model, OLAP commercial environments such as they are currently designed in traditional applications are used to provide means for the analysis of facts that are depicted by numeric data (e.g., sales depicted by amount or quantity sold). However, in numerous fields, like in medical or bioinformatics, multimedia data are used as valuable information in the decisional process. One of the problems when integrating multimedia data as facts in a multidimensional model is to deal with dimensions built on descriptors that can be obtained by various computation modes on raw multimedia data. Taking into account these computation modes makes possible the characterization of the data by various points of view depending on the user's profile, his best-practices, his level of expertise, and so on. We propose a new multidimensional model that integrates functional dimension versions allowing the descriptors of the multidimensional data to be computed by different functions. With this approach, the user is able to obtain and choose multiple points of view on the data he analyses. This model is used to develop an OLAP application for navigation into a hypercube integrating various functional dimension versions for the calculus of descriptors in a medical use case.

Databases of homologous gene families for comparative genomics

BMC Bioinformatics (2009)

Simon Penel Anne-Muriel Arigon Jean-François Dufayard Anne-Sophie Sertier Vincent Daubin

Abstract Background Comparative genomics is a central step in many sequence analysis studies, from gene annotation and the identification of new functional regions in genomes, to the study of evolutionary processes at the molecular level (speciation, single gene or whole genome duplications, etc.) and phylogenetics. In that context, databases providing users high quality homologous families and sequence alignments as well as phylogenetic trees based on state of the art algorithms are becoming indispensable. Methods We developed an automated procedure allowing massive all-against-all similarity searches, gene clustering, multiple alignments computation, and phylogenetic trees construction and reconciliation. The application of this procedure to a very large set of sequences is possible through parallel computing on a large computer cluster. Results Three databases were developed using this procedure: HOVERGEN, HOGENOM and HOMOLENS. These databases share the same architecture but differ in their content. HOVERGEN contains sequences from vertebrates, HOGENOM is mainly devoted to completely sequenced microbial organisms, and HOMOLENS is devoted to metazoan genomes from Ensembl. Access to the databases is provided through Web query forms, a general retrieval system and a client-server graphical interface. The later can be used to perform tree-pattern based searches allowing, among other uses, to retrieve sets of orthologous genes. The three databases, as well as the software required to build and query them, can be used or downloaded from the PBIL (Pôle Bioinformatique Lyonnais) site at http://pbil.univ-lyon1.fr/ .

Développements d'outils pour l'aide à l'identification dans les grandes banques de familles de gènes

Anne-Muriel Arigon

Le nombre de sequences genomiques disponibles augmente tres vite du developpement de methodes de sequencage massif. La classification de ces sequences est necessaire et permet l'etude de leurs relations evolutives. Des outils bioinformatiques automatises sont indispensables pour effectuer ces operations d'identification de facon precise et rapide. Nous avons developpe HoSeqI (Homologous Sequence Identification), un systeme permettant d'automatiser l'identification de sequences dans de grandes banques de familles de genes homologues. HoSeqI propose une interface accessible sur internet (http://pbil. Univ-lyon1. Fr/software/HoSeqI/) afin d'identifier une sequence et de visualiser l'alignement et la phylogenie obtenus. Un autre programme, derive d'HoSeqI, a ete implemente pour l'ajout automatique de sequences genomiques aux banques de familles. Enfin, un travail sur l'identification automatique de sequences bacteriennes d'ARN 16S et la detection de sequences chimeres a ete effectue

A multiversion model for multimedia data warehouse

Anne-Muriel Arigon Anne Tchounikine Maryvonne Miquel

The traditional multidimensional models have a static structure where members of dimensions are computed in a unique way. However, multimedia data is often characterized by descriptors that can be obtained by various computation modes. We define these computation modes as "functional versions" of the descriptors. We propose a Functional Multiversion Multidimensional Model by integrating the concept of "version of dimension". This concept defines dimensions with members computed according to various functional versions. This new approach integrates a choice of computation modes of these members into the model, in order to allow the user to choose the best representation of data. We implement a multimedia data warehouse in the medical field by integrating the multimedia data of a therapeutic study into a multidimensional model. We formally define a conceptual model and we present a prototype for this study
