Health and Biomedical Information
Chapter 1 defined the basic terminology of information retrieval (IR) and presented some models of the use of IR systems. Before proceeding with the details of IR systems, however, it is worthwhile to step back and consider the more fundamental aspects of information, especially as it is used in the health and biomedical domain.

Consideration of this topic allows a better understanding of the roles as well as the limitations of IR systems.
