What does "Performing unique to ensure RDF semantics..." mean? (IndexBuilderMain log)

[hannahbast]

Can somebody briefly explain this to me?

There is probably a better and clearer way to say this.

Yes, I agree. It's just a unique over the list of all triples, because afaik the RDF (and thus turtle, etc) graph has a set of edges and there is no concept for duplicate triples/edges, yet automatically generate KB input files featured duplicates on some occasions (e.g. after reconciliation). To have identical behavior/output to the triples scores we compared QLever to in our evaluation, the unique was needed
