In multidisciplinary medical services (e.g. Intensive Care Units or Pain Management Centers), Case-Based Reasoning systems require good case representations. When multiple disorder cases must be stored in the same case memory, a highly flexible representation is required. The use of ontologies can provide a top level formal description on case structure, and the capability of reasoning. This work proposes a case representation ontology for medical domains, covering aspects related to the flexibility of case structure and the importance of the temporal dimension. Finally, this paper shows the possible benefit of the proposal by presenting a case-retrieval system based on this ontology for Intensive Care Unit domains. KEY WORDS Case-Based Reasoning, Case Representation, Ontologies.
