Research Groups | Artificial Intelligence

The objective of the Group of Artificial Intelligence (AI) is the development of theoretical and applied research on methods and techniques for AI used in several parts of this broad area.
Research results are used in the development of systems aimed at the following application areas: education, petroleum industry, medicine, Internet, traffic, bioinformatics, natural language processing, simulation of complex environments and social simulation, image processing, data mining; corporate memories; systems to support decision-making; fraud detection; speech recognition, computer education; intelligent games and robotics.

Members of the Research Group

Research Themes

  • Simulation of Complex environments: traffic simulations, traffic control, game theory, models and tools for Social Simulation.
  • Image Processing: automatic image analysis for pattern recognition, novelty detection and information extraction.
  • Knowledge Discovery and Management and Data Mining: information extraction from databases including distributed databases.
  • Fraud Detection: fraud detection systems using AI techniques.
  • Natural Language Processing and Speech Recognition: development of techniques and systems for text and speech-based computer interactions. Tools and systems for supporting the development of electronic dictionaries and written text processing (newspapers, books, blogs, ..).
  • Computing in Education: development of mobile (e.g. cell phones, palmtops, etc.) and distance education systems. Intelligent tutoring systems and Web-based student profile tracking systems.
  • Intelligent Games: development of techniques and systems for intelligent games in remote and mobile devices (e.g. cell phones, palmtops, etc.).
  • Autonomous and Intelligent Robotics: robotic systems that use Artificial Intelligence techniques for autonomous processing.
  • Bioinformatics: investigation and implementation of techniques and systems for supporting genome sequencing.
  • Knowledge Engineering and Ontologies: knowledge acquisition and conceptual modelling for building knowledge systems. Reasoning and modelling for visual knowledge.
