The activities of the LIA are organized around three themes:


  • Human-machine dialogue: modeling language and concepts for analyzing corpus of dialogues and strategies of interpretation and dialogue for voice access to servers
  • Automatic processing of natural language writing: application to modeling of natural language writing in search of information in large databases of textual records
  • processing of natural language skills: modeling the speech and speaker - application to the realization of recognition systems in different contexts (systems of speech recognition, speaker, language, multimedia indexing, etc.).

Rapport d'activité du groupe Langage pour la période 2006/2010

Research projects related to this theme:

  • BIOBIMO : Bimodal Biometrics on MObile
  • MISTRAL : Open Source Platform for Biometric Authentication
  • AVISON : multilingual indexing of audiovisual documents
  • RP2M : multi document summarization, plurimedia, multi-view
  • PIITHIE : Plagiarism and Impact of Textual Information sought in a context Interlingue

Operations research and optimization:

application of methods and algorithms of OR to optimize resources in various contexts, including networks and natural language processing written and oral;

research projects related to this theme:

  • TSP-VRP-PROFITS : Problems of commercial travelers and vehicle routing with earnings
  • TAD : Transport on demand
  • GENCOLVRP : Column generation for solving vehicle routing
  • HYBRIDEH : Hybridization exact methods - heuristic methods
  • FAP : Problems frequency assignment for Hertzian transmissions

networks and multimedia applications:

application of work on architectures and networking protocols development of security systems, mobile and streaming media.

research projects related to this theme:

  • Cladis : Cross-Layer Design to Improve Security in Mobile Ad-Hoc Networks
  • NGABIN : Biologically Inspired Networking Games And Networks
  • ADSANET :-Hoc and Sensor Networks: Routing, multicast and location
  • VANETOOL : platform for modeling and simulating vehicle networks
  • Crawn : Cognitive Radios in Wireless Ad Hoc Networks
  • WINPAP : Wireless Networks: Protocols, Applications, and Performance

If, in each of these themes, fundamental and applied work are oriented towards a particular objective, it is clear that the connection between them (especially as regards the activities of the first theme on one side and the last two themes of a other side) gives coherence to all of our science. These scientific activities are developed in full coherence with the formations of the University of Avignon (UAPV) in this area. Indeed the three themes Language, RO RAM and 3 correspond to the route search and professional Master of Computer Engineering and Mathematics.
