2. Relationssubject – object (owned buildings and cars)subject – rulessubject – communitycommunity – rulescommunity – object (e.g. buildings, cars, parks)community – divisions of labor (e.g. roles)community – artifacts (e.g. beliefs, documents like
acts)object – artifact (property acts, blueprints)object – subject (owner)object – rule (of use)

3. Triples
May be triangles in the activity diagramOther mediating artifactsWill be used for knowledge acquisition Intelligent quering

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
