Metathesaurus Relations • Symbolic relations: ~8 M pairs of concepts • Statistical relations: ~6 M pairs of concepts (co-occurring concepts) • Mapping relations: ~150,000 • Categorization: Relationships between concepts and semantic types from the Semantic Network
Symbolic relations • Relation ◦ Pair of “atom” identifiers ◦ Type ◦ Attribute (if any) ◦ List of sources (for type and attribute) • Semantics of the relationship: defined by its type [and attribute] Source transparency: the information is recorded at the “atom” level
