Question

What is the primary challenge associated with ontology mismatches in Linked Data integration?

a.

They affect the transformation step of the ETL process

b.

They lead to the duplication of classes in integrated knowledge bases

c.

They occur mostly at the property level

d.

They affect the extraction step of the ETL process

Posted under Big Data Computing

Answer: (d).They affect the extraction step of the ETL process Explanation:Ontology mismatches in Linked Data integration primarily affect the extraction step of the ETL process, as they involve differences in classes and properties used to express equivalent knowledge in source knowledge bases.
