RDF Graph Model
We propose a new formal model for representing any set of RDF triples as mathematical graphs.
Example
| Triple | Subject | Predicate | Object |
|---|---|---|---|
| T1 | BobDylan | isMarriedTo | SaraLownds |
| T2 | BarackObama | isMarriedTo | MichelleObama |
| T3 | isMarriedTo | rdfs:subPropertyOf | isSpouseOf |
| T4 | BobDylan | isSpouseOf | SaraLownds |
| T5 | BarackObama | isSpouseOf | MichelleObama |
For the set of RDF triples in the table above, we explain how each approach represents them in the graph.
The NLAN model
The BI model
eI_i
The LDM model
More complex examples
Singleton_Property approach to representing
