Lexical Unique Identifier(English)

• The unique identifier of a term in the Metathesaurus. Terms are different from strings in that they group together strings that are lexical variants of one another. For example, the strings 'Eye', 'eye', and 'eyes' all have different SUIs, but share the same LUI. LUIs are not generally maintained over time, as their generation depends on the algorithms used in the Lexical Variant Generator program, which may change from time to time
