Information Systems

Provide information to users information retrieval for a query in a

collection of data usually keyword-based

navigation (browsing)

Store data

Intelligent information systems

Identify users’ personal characteristics (personalize) Try to structure the dialog Meaning(vs. keyword)-based knowledge-based NLP ontology metadata

Personalization

knowledge profile goals beliefs intentions perspective

Further work

Specific to the IIS: Implement the knowledge acquisition

and knowledge-processing modules

General: Develop the socio-cultural ontology Develop software for conflict

management in dialogs, based on ontologies and Toulmin’s argumentation theory

Folksonomy integration support
