Use GROUP BY ?itemlabel ?year in SPARQL Wikidata LaureateDetail query.
This is for avoiding duplicate record when a laureate have more than one photo in wikidata (like Wolfgang Pauli).
I think we can use aggregate functions like SAMPLE() or GROUP_CONCAT()
I tried but it didn't work.
I don't have time for it now, i need to review SPARQL.
