Semantic annotation of online data/information will support the location and retrieval of such taskspecific expertise through intelligent agents, which allows to perform context-aware queries. This paper examines the theoretical background of knowledge representation for semantic annotation (ontologies) and reports of an ongoing project to implement an ontology into an intelligent agent system to support flood-risk management.Text/Conference Paper
