A lexical metaschema for the UMLS semantic network
2005

Objective: A metaschema is a high-level abstraction network of the UMLS's Semantic Network (SN) obtained from a partition of the SN's collection of semantic types. Every metaschema has nodes, called meta-semantic types, each of which denotes a group of semantic types constituting a subject area of the SN.
