We continue our collaboration on clustering and web usage mining and we start a collaboration on social network data analysis with F.A.T. De Carvalho from Federal University of Pernambuco (Recife) and his team.
A scientific project submitted by F. De Carvalho and Y. Lechevallier has been accepted by FACEPE and INRIA. The project starts on 01/2010 and ends on 12/2011. Researches and students are concerned by this project from AxIS and CIn-UFPE side. It aims at developing methods of clustering of relational data and social network data analysis tools.
Y. Lechevallier has visited the UFPE. During its stay, in collaboration with F. de A.T. de Carvalho, they continued the design of dynamic clustering models based on adaptative distances and they finalized the elaboration of dynamic clustering models based on adaptative distances suitable to symbolic interval data. Three complete papers on this subject have been published this year on "Pattern Recognition"  , "Pattern Recognition Letters"  , and "IEEE Transactions on System Man and Cybernetics, Part A"  , journals.
M. Csernel, F. de A. T. de Carvalho and K. Silva published a work  issued from her Master Thesis (about the adaptation of Fuzzy clustering on symbolic data, specially in presence of rules as background knowledge) in the proceedings of the 2009 International Joint Conference on Neural Networks published by IEEE computer society.
During L'année de la France au Brésil the French-Brazilian workshop on data mining happenned in Recife form 5 to 7 May 2009 (http://www-roc.inria.fr/axis/modulad//Workshop_Franco_Bresilien/index.htm ). The program of the workshop included 3 tutorials, 9 invited conferences and 16 scientific presentations. There were about 100 partitipants. F. de A. T. de Carvalho and Y. Lechevallier have participated actively on the organisation of this workshop.
Y. Lechevallier gave an invited talk  on some clustering methods on dissimilarity or similarity matrices at the workshop franco-brésilien (Récife).
The project (2009-2013) with Casablanca University and ENSAM (Meknes) about the WRUM proposal (Web Redesign based on Usage Mining) accepted in may 2008 started this year for 4 years (2009-2013). This project received fundings from the Research and Education Ministery and is managed by the CSPT commission. In this project close to the three topics of AxIS, the chosen application domain is the e-learning.
Hicham Behja, Prof à ENSAM Meknès is in charge of the WRUM project with the support of Prof. A. Marzark (Univ Casablanca).
B. Senach and B. Trousse had their first visit to Casablanca in the context of the WRUM project. During their visit, Two meetings were organised: one at the University of Casablanca in order to have a demonstration of the e-learning platform used at OFPPT by M. Naamary (OFPPT) and a second one (october 26) with OFPPT (Office de la Formation professionnelle et de la Promotion du travail ) at Casablanca in order to present the WRUM project and to identify future collaborations.
H. Behja and A. Marzark made two visits in France in the context of the WRUM project in order to work on the different thesis subjects: september 23 - october 2 and december 7-13.
Participant : Yves Lechevallier.
Y. Lechevallier is involved in the STIC program between France-Tuisia. With M-A. Aufaure (CNAM), they supervised 4 masters and 2 thesis (Riadi Lab, ENSI Tunis) in this project. These masters and thesis subjects are about web mining (usage, content and structure, using different methods) and ontology construction from heterogeneous sources. This year M. R. Haddad  ,  and M. Hadjouni  ,  participated actively to the themes of our STIC on personalization and an integration of space and accessibility in Web personalization with the co-supervision of H. Baazaoui Zghal, M.-A. Aufaure, C. Claramunt and Y. Lechevallier.
In this STIC project, we welcomed from ENSI (Tunisia) at Rocquencourt: M.R Haddad (January-February), M. Hadjouni (May to July, November), N. Ben Mustapha and I. Megdiche (May to July).
