A simplification of this is:
CONSTRUCT {?x owl:sameAs ?y)
WHERE {
?x a sioc:UserAccount .
?y a sioc:UserAccount .
?x sioc:last_name ?y .
?y sioc:last_name ?z
FILTER (?x != ?y)
}
Run this in the SPARQL view, assert or infer the resulting triples,
then run OWL inferences. All of this can be automated in a
SPARQLMotion script.
There are many advantages of using SPARQL over SWRL, including that
the language is more expressive and is a W3C standard.
