Semantic Types are a set of broad subject areas that provide a consistent categorization of concepts represented in the Metathesaurus. Semantic Types are arranged into two mutually exclusive hierarchies, Entity and Event.
Semantic Types help summarize the content of a source.
Each Metathesaurus concept is assigned at least one semantic type, many have more than one.
The report displays the most frequently assigned semantic types in descending order, up to a total of 1%.
The 'Count' field below is the number of concepts assigned a specific semantic type and containing at least one atom from the source.
The 'Percentage' field below is the count relative to the total number of concepts that contain an atom from that source.
The MRSTY file contains one row for each Semantic Type assigned to each concept. All Metathesaurus concepts have at least one entry in this file.
