Unable to see Max in SPARQL Query - sparql

Question

Im trying to query a knowledge graph and im trying print the max occurrence of ?n in the result and i have tried running following query but it just doesn't prints anything
here is my SPARQL Query
PREFIX : <http://www.tafsirtabari.com/ontology#>
PREFIX RDF:<http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
select
?n
(MAX( xsd:int(?countOfSharedLikedItems)) as ?max)
(COUNT(?n) as ?countOfSharedLikedItems)
where {
?h :hasTheme :lugha .
?h RDF:type :Hadith .
?h :hasHadithNo ?o.
?p :isPartOfHadith ?h.
{
?p :hasNarratorSegment ?nc.
?nc :refersTo+/:hasName ?n.
}
Union
{
?p :hasRootNarratorSegment ?rnc.
?rnc :refersTo+/:hasName ?n.
}
}
i have also tried following by using group by ?n
PREFIX : <http://www.tafsirtabari.com/ontology#>
PREFIX RDF:<http://www.w3.org/1999/02/22-rdf-syntax-ns#>
select
(MAX(?countOfSharedLikedItems) as ?max)
(COUNT(?n) as ?countOfSharedLikedItems)
where {
?h :hasTheme :lugha .
?h RDF:type :Hadith .
?h :hasHadithNo ?o.
?p :isPartOfHadith ?h.
{
?p :hasNarratorSegment ?nc.
?nc :refersTo+/:hasName ?n.
}
Union
{
?p :hasRootNarratorSegment ?rnc.
?rnc :refersTo+/:hasName ?n.
}
} group by ?n

You can try this
PREFIX : <http://www.tafsirtabari.com/ontology#>
select (COUNT(?o ) AS ?triples) where {
?k :heardFrom ?o
}
6. Which RAWI narrated most hadiths about TOPIC_A
PREFIX hash: <http://www.tafsirtabari.com/ontology#>
PREFIX W3:<http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX : <http://www.tafsirtabari.com/ontology#>
SELECT ?total WHERE{
select DISTINCT ?n (COUNT(?n) as ?total) where {
?commentary hash:mentions hash:اهل_المعرفه .
?segment hash:containsCommentary ?commentary.
?segment ?Fr ?h .
?h W3:type hash:Hadith.
?p :isPartOfHadith ?h.
{
?p :hasNarratorSegment ?nc.
?nc :refersTo+/:hasName ?n.
}
Union
{
?p :hasRootNarratorSegment ?rnc.
?rnc :refersTo+/:hasName ?n.
}
}GROUP BY ?n
}ORDER BY DESC(?total)
LIMIT 1
