Highlights


  • 2009/09 A subset of all our PhD students (and some other students from the LaBRI) took part in the VisWeek VAST contest 2009. They won two awards :
    • Traffic Mini Challenge:  Innovative visualization & excellent description
    • Flitter Mini Challenge:  Representation of uncertainty in rules & in visualization
  • 2008/11 The SPANGEO ANR project was elected as Highlight of the Masses de données 2005 call. The project gathered quantitative geographers and computer scientists in an effort to develop and exploit results from network science. The project had a decisive impact on the geographers ability to study data describing how network flows organize, confronting multi-level organizations of flows against territorial strategies.

  • 2008/06 A subset of all our PhD students (and our intern Umang Sharan) took part in the VisWeek VAST contest 2008 (mini challenge number 3). The primary task of the mini challenge was to provide characteristics for the Catalano/Vidro social network and to provide evidence on the temporal changes occuring in this social structure. The data set gathered information on 9834 (mobile) phone calls between 400 cellphones over a 10 day period in June 2006 on the Isla Del Sueno. The records were expected to provide critical information about the Catalano social network structure. Given the quantity and nature of the data involved, our student team  developed a visualization environment built on top of our framework Tulip to help analyze the evolution of the call structure over time.  This work won our team a publication in the VisWeek Conference Compendium.

  • 2008/04 Our Graph Visualization framework was released under version Tulip 3.0 last April. One of the new features provided with this version is a \emph{plugin manager}  easing the download and update of the entire collection of plugins developed by the team through a server. Each time the Tulip GUI is launched, Tulip automatically connects to the plugin server hosted at  LaBRI to check the availability of new plugins or application updates. Each connection is logged with the current date and client IP initiating the connection. Exploring the collection of user logs provided feedback on the actual use of the framework by our user community. Assuming that different IPs correspond to different users, excluding LaBRI IPs, the statistics showed that our 1600 users distribute over 69 different countries. Based on user logs collected since the tracking system was launched, about 40 different users from  10 different countries launch the application everyday. Other statistics extracted from sourceforge.net (hosting  the Tulip sources and binaries) and Tulip's website also reveal the increasing evolution of our user community:
    • each new version of Tulip is downloaded about 3300 times and this number has increased of 38% during the last twelve monthes period.
    • Tulip's website is visited about 2500 times per month and this number has increased of 15% over the same period of time.

  • 2008/01 Guy Melançon was appointed as a member of the steering committee for the I3 journal. The Information - Interaction - Intelligence (I3) Journal was founded by members of the research group GDR I3, created by the CNRS in January 1998. The journal serves as a forum favoring the dissemination of interdependent and interdisciplinary research involved in information retrieval, database, human-machine communication and artificial intelligence. The recent developments in these fields call for cross-discipline collaborations and perspectives. The I3 journal intends to promote inter-disciplinarity working at the development of common terminology, concepts, typologies, methods and ontologies and aiming at the identification of a unified perspective on research issues. The journal is disseminated both as a traditional paper journal published by Cépaduès and as an electronic journal on the web.

  • 2007/06 Fanny Chevalier working under the supervision of Maylis Delest and Jean-Philippe Domenger has been awarded the Best Student Paper Award at the CBMI 2007 International Conference for her work on object retrieval in video content based on graph mining. CBMI is a yearly International Conference bringing together the various communities involved in the different aspects of Content-Based Multimedia Indexing. It is the main international forum for the presentation and discussion of the latest technological advances, industrial needs and product developments in multimedia indexing, search, retrieval, navigation and browsing.
