The knowledge-base sapper, and his four explosive triples.

Okay, so here's some non-standard use of RDFS/OWL that Axel Polleres came up with:

rdfs:subClassOf rdfs:subPropertyOf rdfs:Resource .
rdfs:subClassOf rdfs:subPropertyOf rdfs:subPropertyOf .
rdf:type rdfs:subPropertyOf rdfs:subClassOf .
rdfs:subClassOf rdf:type owl:SymmetricProperty .


Full reasoning on this according to some ruleset (say pD*: -- i.e., OWL-Horst -- rules rdf1, rdfs4a, rdfs4b, rdfs7x, rdfp3) gives everything. I'll let you work that one out. By everything, I mean every possible (albeit finite) combination of identifiers that constitute a valid RDF triple: the number of resulting triples equals the number of unique identifiers, cubed. Stick those four statements into a web-crawl, do some happy-go-lucky rule-based reasoning and you have problems. Of course this is only one such example. Watch this space.

...oh, and before I go, it doesn't even take four triples (pD*: rdf1, rdfs4a, rdfs4b, rdfp6, rdfp7, rdfp9, rdfp10, rdfp11).

rdf:type owl:sameAs owl:sameAs .

Even if you apply for online paper help, you can be certain about getting quality content delivered to you. The quality of the thesis depends on the experts and most experts work on delivering the best content. The quality and professionalism come naturally because the experts who work on the thesis are so good at the topics and they just shed all the information they know and since they are doing this for so long, their presentation is also unmatchable.
