Please help me with my hw question I am very stuck! Thank you
5.) [15 points] Consider the following RDF graph: rdfs:subClassOf Person Actor rdfs:subCla rdf:type rdfsrange rdf type rdfs:Class stars Director rdf type rdf:type rdf:type jackson Movie reeman rdf Propery name name rdf:type star directs rdf:type Martin Freeman hobbit Peter Jackson stars title mckellan year name The Hobbit 2012 lan McKellan CISC 481/681 Program 1 Page 4 of4 Using the RDFS entailment rules rdfs2, rdfs3, rdfs5, rdfs7, rdfs9, and rdfs11 in Section 7.3 of the W3C RDFS semantics specification http://www.w3.org/TR/2004/REC.rdf mt-20040210/#rules], determine what triples can be inferred from the example in Problem #1. (You may ignore the other entailment rules because they do not add anything particularly interesting here). Assume the boxes contain literals (e.g. integer 2012, string "The Hobbit"). You can extend the drawing, or write out the triples in a Turtle-like style (e.g. Movie rdf:type hobbit. hobbit stars freeman.). Don't sweat syntax 6.) [9 pts] According to the RDFS Schema recommendation, a property can have multiple rdfs:range statements. When this occurs the range of the property is treated as the intersection of the individual ranges. What advantage does this have over using the union of the individual ranges to determine the actual range? [Hint: Consider the distributed design of RDF and the inferences that are sanctioned by rdfs:range.] 5.)
