Graph interpretations
-
The interpretation for an RDF graph is based on extension
functions:
-
- properties (predicates) are all
part of the
vocabulary (in contrast to Description Logic)
- an interpretation has two steps:
-
- all elements of the vocabulary are mapped by a mapping I
on a set Δ,
-
- i.e., predicates are mapped on elements, too
- a separate extension function is defined (Ext), that for
each predicate maps to Δ × Δ
- extra constraints on the interpretation ensure a “proper”
mapping of predicates
