National Initiatives

AxIS is involved in one ARC from INRIA and several national working groups.

ARC SéSur

Participants : Wei Wang, Florent Masseglia, Yves Lechevallier, Brigitte Trousse, Alice Marascu.

SéSur (2007-2008) for “Sécurité et Surveillance dans les flots de données” is an ARC which involves Dream (IRISA), LGI2P (Ecole des Mines d'Alès) and LIRMM (Montpellier). The goal of SéSur is to propose solutions for the security, monitoring and diagnosis of data streams. Data streams have two major characteristics: 1) they are the vital signals of the considered system and their analysis is of great interest and 2) their production rate is so high that actual technology is not able to process them in a satisfying way. We are mainly interested in monitoring the systems that produce data streams. In 2008, partners of SéSur have published research papers in national and international conferences [91] , [99] and 4 research reports [92] , [100] , [80] and [36] , [67] . Three papers (EGC, PAKDD, SAC) and one poster (EGC) from this ARC have been accepted in conferences in 2009.

EGC Association

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:

• B. Trousse co-chaired with F. Guillet the 8th francophon conference in “Extraction et Gestion des Connaissances” [59] and was responsible of the conference organisation at Inria Sophia Antipolis. More than 240 persons attended the conference (january 2008). [59] , [17]

• M.-A; Aufaure, Y. Lechevallier, F. Masseglia, B. Trousse (23 January, 2007) are member of the workshop of “Fouille de données complexes” at EGC08.

GDR-I3

AxIS is concerned by three working groups of the GDR-PRC~I3 National Research Group “Information - Interaction - Intelligence” of CNRS: working Group 3.4 (GT) on Data Mining, Gracq , Working Group 3.7 on “Sécurité des Systèmes d'Information”.

Other Collaborations
