concept equivalence

This is a synonym for semantic equivalence.

semantic equivalence

The relationship between two classes that have the same logical meaning.

Notes

• The equivalent classes may be represented in different ways for example as SNOMED CT concept definitions, SNOMED CT expressions, or axioms expressed using a syntax such as OWL Functional Syntax.

• Semantic equivalence is represented by the Ξ symbol or by a sequence of three equals signs === .

Example

• The expression below asserts that the concept 80146002 | Appendectomy| has semantic equivalence with 71388002 | Procedure| with method 129304002 | Excision - action| applied to the direct site 66754008 | Appendix structure| .

80146002 |Appendectomy| === 71388002 |Procedure| : { 405813007 |Procedure site - Direct| = 66754008 |Appendix structure| , 260686004 |Method| = 129304002 |Excision - action| }
