ABSTRACT -- There are currently over 50 biomedical terminologies of various scope and structure, designed to serve various purposes. After a brief presentation of these terminology systems, the talk will focus on their structure, seen as one way to organize knowledge. Three types of relationships among terms will be examined: synonymy, hierarchical relationships and cross-references. Finally, the differences between terminologies and other knowledge representation systems (medical knowledge bases, medical ontologies) will be discussed, and recent approaches to organize biomedical knowledge will be briefly presented.
