Programming, Logic and Intelligent Systems

Organization profile

Organisation profile

The PLIS (Programming, Logic and Intelligent Systems) group at Roskilde University investigates foundations, tools and languages for the development of adaptable, reliable, human-oriented computer systems.

The group's research covers theoretical foundations, languages, tools and semantic models together with application areas. The main research topics are:

  • Knowledge-based systems and intelligent interaction with systems.
  • Logic and knowledge representation.
  • Programming languages and tools.

Long-term objectives

  • To develop tools and techniques allowing intuitive interaction with information and knowledge-based systems, including natural language understanding and generation, and interpretation of interaction with respect to a context that is constantly changing.
  • To construct logics and structures capable of creating and reasoning about models of the environment and human activities, including direct modelling of concepts familiar to humans, common-sense concepts and representation of dynamically changing situations.
  • To develop languages, methods and tools for software production, analysis and transformation, allowing automatic generation, checking and evolution of software systems.
