We continue our collaboration on clustering and web usage mining with F.A.T. De Carvalho from Federal University of Pernambuco (Recife) and his team.
A scientific project submitted by Francisco De Carvalho and Yves Lechevallier has been accepted by FACEPE and INRIA. The project started from 04/2006 and ends on 03/2008. Researches and students are concerned by this project from AxIS and CIn-UFPE side. It aims at developing methods of clustering analysis and web usage mining tools.
Francisco de Carvalho visited AxIS project. During their stays, in collaboration with Yves Lechevallier, they participated to 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. A complete paper has been submitted and accepted to the "Pattern Recognition" journal.
In collaboration with Yves Lechevallier, Alzennyr Da Silva and Fabrice Rossi, Francisco de Carvalho has participated to the elaboration of an approach concerning the construction of summaries via clustering methods of data which evolve overtime. An application of this approach has been done on data from web usage which evolves on the time.
Marc Csernel and Yves Lechevallier visited CIn-UFPE during the first week of mars. Marc Csernel worked also with Kelly Silva on her Master Thesis on the adaptation of Fuzzy clustering on symbolic data, specially in presence of rules as background knowledge.
During "L'année de la France au Brésil" the workshop on data mining has been labelled and is expected to happen in Recife during the first week of May 2009.
Y. Lechevallier pursued his collaboration with A. Ciampi (Univ of McGill, Montréal).
Marie-Aude Aufaure collaborates with Yanwu Yang, Institute of Automation, Chinese Academy of Science, Beijing, on user modelling for the semantic web  and Yves Lechevallier collaborates with Hueiwen Wang, BUAA, Beijing on clustering methods.
The project (duration of 4 years) with Casablanca University and ENSAM (Meknes) about the WRUM proposal (Web Redesign based on Usage Mining) has been accepted in may 2008 and received a financing from Morocco Telecom. In this project, AxiS will have to use multi-sites log analysis to redesign Web sites. The project hasn't started this year.
We maintained our contacts with the Computer Science department of the West University of Timisoara (Prof Viorel Negru), in particular via the SYNASC conference every year. B. Trousse discussed with V. Negru about future collaborations at ICT conference (Lyon) in november 2008.
Marie-Aude Aufaure and Yves Lechevallier are involved in co-supervision of 4 masters in the context of the STIC Tunisie and/or 2 thesis (Riadi Lab, ENSI Tunis) and participated as invited speakers  ,  in the workshop Ecol'IA08 "Apprentissage et fouille de données : de la théorie à la pratique" at Hammamet (Tunisie) during march 2008. These masters and thesis subjects are about web mining (usage, content and structure, using different methods) and ontology construction from heterogeneous sources  ,  ,  ,  ,  .
