Question 1 of 3

1. Question

What actually distinguishes a taxonomy from an ontology?

A taxonomy carries formally defined axioms a reasoner can act on, while an ontology uses broader and narrower relationships for navigation
Correct Incorrect Correct answer

A taxonomy has essentially one working relationship, broader and narrower, and no logic, while an ontology has arbitrary formally defined relationships and axioms a reasoner can act on
Correct Incorrect Correct answer

A taxonomy is the populated instance data, while an ontology is the schema layer above it
Correct Incorrect Correct answer

A taxonomy is published in OWL, while an ontology is published in SKOS

Question 2 of 3

2. Question

What does the lesson say about the semantics of skos:broader?

It is equivalent to rdfs:subClassOf, so SKOS hierarchies are reasoned over exactly like OWL class hierarchies
Correct Incorrect Correct answer

It is a transitive property whose entailments a reasoner uses to derive new subsumptions automatically
Correct Incorrect Correct answer

It is a SHACL constraint component that rejects concepts filed under the wrong parent
Correct Incorrect Correct answer

Its semantics are intentionally weak and carry no logical entailment beyond what they say, which lets information architects publish useful structures without committing to formal logic
Correct Incorrect Correct answer

Correct / 1 Points

Incorrect / 1 Points
Question 3 of 3

3. Question

The lesson describes a newer, LLM-flavoured failure mode. What is it?

Over-engineering: eighteen months of OWL axioms modelling the metaphysics of agreement, which makes reasoners hang
Correct Incorrect Correct answer

Publishing a SKOS thesaurus where a full OWL ontology was required, which breaks language tagging on labels
Correct Incorrect Correct answer

Under-engineering: a schemaless extracted graph that demos well and then cannot answer how many distinct suppliers exist in Germany, because Siemens, Siemens AG and SIEMENS are three nodes and nothing defines what a supplier is
Correct Incorrect Correct answer

Loading billions of triples without a named-graph strategy, which destroys provenance and per-graph access control
Correct Incorrect Correct answer

Correct / 1 Points

Incorrect / 1 Points
