Why a semantic network • Semantic Types serve as high level categories assigned to Metathesaurus concepts, independently of their position in a hierarchy • A relationship between 2 Semantic Types (ST) is a possible link between 2 concepts that have been assigned to those STs ◦ The relationship may or may not hold at the concept level ◦ Other relationships may apply at the concept level
Relationships may inherit semantics Semantic Network Fully Formed Anatomical Structure isa Body Part, Organ, or Organ Component location of Disease or Syndrome Pathologic Function isa Biologic Function isa Adrenal Cortex Metathesaurus location of Adrenal Cortical hypofunction
