National Initiatives

AxIS is involved in several national working groups.

CNRS RTP 12: ``information et connaissance: découvrir et résumer''

In the context of the pluri-disciplinary thematic http://rtp12.loria.fr , we participated to the CNRS Specific Action (AS 120) ``Disco Challenge'' animated by J.F. Boulicaut and B. Crémilleux. We made a presentation to the Discovery challenge proposed at PKDD/ECML 05 [26] .

CNRS Action Concertée Incitative : ``Histoire des savoirs''

This initiative (ACI RNR TTT Grammaire et math matique dans le monde indien 17/01/03 - 17/01/06) associates several French research teams from various research fields, such as computer science, data analysis, and Sanskrit literature. The main goal of this action is to provide help for the construction of critical edition of Indian manuscripts in Sanskrit, and to provide pertinent information about the manuscripts classification (construction of cladistic trees). The expected tools will not be restricted to Sanskrit language. This action is completed according some different aspects by the European AAT project which allows us to collect more Sankrit manuscripts and to care about some interactive aspect that we where not able to take into account with the ACI dotation. The action will end in december 2006.

EGC National Group on Mining Complex Data

URL: http://eric.univ-lyon2.fr/projets.php

AxIS members participated actively this year to the Working Group ``Fouille de données complexes'' created by D.A Zighed in June 2003 in the context of the EGC association:

• F. Masséglia with P. Gancarski (LSIIT, Strasbourg) co-organised and co-chaired the second workshop ``Fouille de données complexes dans un processus d'extraction de connaissances'' (January 18, 2005) [15] . Y. Lechevallier and B. Trousse were members of the program committee.

• F. Masséglia, B. Trousse participated to the meeting of the two national working groups of the national group on mining complex data in relation with the working group 3.4 ``Data Mining'' of the GDR I3 (May, Paris). F. Masséglia with O. Boussaïd co-animated one of these two working groups: ``organisation and structuration of complex data''.

• H. Behja, F. Masséglia and B. Trousse participated in the main meeting of the working group held in Lyon (ERIC) on September 9, 2005. H. Behja made a presentation of his PhD thesis ``Vers une approche Web sémantique pour le processus ECD''.

GDR-I3

AxIS participated to three working groups of the GDR-PRC~I3 National Research Group ``Information - Interaction - Intelligence'' of CNRS:

• Working Group 3.4 (GT) on Data Mining animated by P. Poncelet and J.M. Petit. H. Behja, F. Masséglia and B. Trousse participated to the Paris meeting (May) in collaboration with the working group FDC. F. Masséglia and A. Baldé participated to the second meeting at Lyon (November 21). A. Baldé made a presentation of his PhD thesis ``Utilisation de métadonnées pour l'aide à l'interprétation de classes et de partitions''.

• Gracq ( Groupe de Recherche en Acquisition des Connaissances ) ( GRACQ ): B. Trousse.

• Working Group 3.1 ``Sécurité des Systèmes d'Information'' animated by D. Boulanger and A. Gabillon: F. Masséglia and B. Trousse.

Other Collaborations

• LIRMM (Montpellier) and Ecole des mines d'Alès (LGI2P): F. Masséglia with M. Tesseire (LIRMM) and P. Poncelet (LGI2P) proposed 1) a survey related to sequential pattern mining method and issues [20] 2) a method dedicated to the management of time constraints in the generalized sequential pattern extraction process [75] and 3) a distributed algorithm for mining users behaviours on a P2P network (a paper about this work has been accepted for the 6th French conference on knowledge extraction and management (EGC'06)).

• ENST: Y. Lechevallier collaborated with Georges Hébrail (ENST).

• Two ARC proposals: 1) ARC SéSur: ``Sécurité et Surveillance dans les data streams'' (resp: F. Masséglia) with M.O Cordier (DREAM, IRISA) P. Poncelet (LGI2P, Alès) and M. Teisseire (LIRMM, Montpellier); 2) ARC Valex: `` Vérification et exploitation de collections de documents scientifiques semi-structurés'' (resp: A.-M. Vercoustre) with Annie Morin (TEXMEX, IRISA Rennes), A. Napoli (Orpailleur, INRIA, Nancy), Nathalie Aussenac (IRIT, Toulouse)

• GRIMM-SMASH team (Université Toulouse Le Mirail): F. Rossi works with Nathalie Villa on Support Vector Machines and functional data (cf section 6.3.2 and [46] , [44] ).

• LITA EA3097 (Université de Metz): F. Rossi and A. El Golli work with Brieuc Conan-Guez on the Self Organizing Map for dissimilarity matrices (see section 6.3.1 and [29] ). F. Rossi works with Brieuc Conan-Guez on functional data analysis (cf section 6.3.2 and [22] , [23] , [24] ).
