Making the Conceptual Connections: The UMLS after a Decade of Research and Development

Abstract
The UMLS Section in this issue of JAMIA is dedicated to the memory of Marsden Scott Blois, Jr., a pioneer in medical concept representation. Dr. Blois, an internationally recognized physician-investigator and medical informatician, made important contributions to melanoma research and to biomedical informatics during his distinguished and varied career. His keen insight in the early days of the UMLS project contributed significantly to the future direction and success of the project.
