Group activities and projects aim to the development of:

• Knowledge based systems that solve complicated problems in safety-critical environments cooperatively with their human partners.
• Intelligent interfaces that participate in joint activities with users as active partners, present and organise information coherently and consistently,
• Active learning environments that choose the content and form of information presentation collaboratively with their users in order to satisfy the information needs of the latter.
• Tools and methods for fulfilling the combined needs of information producers and consumers. Information producers aim to provide information that achieves their communicative goals, addresses the needs, interests and satisfy the preferences of their intended audience. Information consumers need systems that tailor information to their background knowledge, preferences and abilities, and satisfy their information needs in various contexts of information use.
• Knowledge management systems in large and distributed organisations. The aim is to investigate, design and develop methods and tools for capturing, organising and distributing intangible knowledge within an organisation.

Towards these goals we investigate issues concerning:

• Methods and tools for the representation of knowledge about information items in the context of the information presentation design task and for the participation of systems in coherent and fluent dialogues with their human partners.
• Architectures and theoretical frameworks for cooperative systems
• Web sites' log files mining for sites' evaluation

Major group competencies are within:

• Ontological and Knowledge Engineering.
• The development of intelligent agents that act and deliberate in dynamic and unpredictable environments.
• Theories and architectures for the developent of cooperative agents
• Reliability measures for evaluating web sites
