To count the number of references in a SPARQL query, you can use the COUNT() function in combination with the DISTINCT keyword. Here's an example query that counts the number of references in a dataset:

1
2
3
4
SELECT (COUNT(DISTINCT ?reference) AS ?count)
WHERE {
  ?subject ?predicate ?reference .
}


This query will return the number of distinct references found in the dataset. Make sure to replace ?subject, ?predicate, and ?reference with the appropriate variables and URIs for your dataset.


You can run this query in a SPARQL endpoint such as DBpedia or Fuseki, or any tool that supports SPARQL queries.
