sparql exclude multiple type hierarchy - sparql

Question

In dbpedia I select some pages with label starting 'A'. Here I'm using additional filter by subject to narrow the set. In original version there are another conditions (result set is much bigger)
PREFIX skos: <http://www.w3.org/2004/02/skos/core#>
PREFIX purl: <http://purl.org/dc/terms/>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX : <http://dbpedia.org/page/>
PREFIX dc: <http://purl.org/dc/elements/1.1/>
PREFIX dbr: <http://dbpedia.org/resource/>
SELECT DISTINCT
?pageType
WHERE
{
{
?page rdfs:label ?label .
?page a ?pageType .
?page <http://purl.org/dc/terms/subject> <http://dbpedia.org/resource/Category:Banking> .
}
FILTER ( strstarts(str(?pageType), 'http://dbpedia.org/ontology') )
}
LIMIT 1000
sparql results
Here I select only page types to be clear with rest of the question.
This is the whole set. Now I want to exclude some pages. Exclude all agents (persons, organization etc):
PREFIX skos: <http://www.w3.org/2004/02/skos/core#>
PREFIX purl: <http://purl.org/dc/terms/>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX : <http://dbpedia.org/page/>
PREFIX dc: <http://purl.org/dc/elements/1.1/>
PREFIX dbr: <http://dbpedia.org/resource/>
SELECT DISTINCT
?pageType
WHERE
{
{
?page rdfs:label ?label .
?page a ?pageType .
?page <http://purl.org/dc/terms/subject> <http://dbpedia.org/resource/Category:Banking> .
MINUS { ?page a dbo:Agent }
}
FILTER ( strstarts(str(?pageType), 'http://dbpedia.org/ontology') )
}
LIMIT 1000
The result.
Ok. Then I want to exclude more types, for example Written_Work. I tried different approaches, but unabled to find the correct one.
This returns nothing:
WHERE
{
{
?page rdfs:label ?label .
?page a ?pageType .
?page <http://purl.org/dc/terms/subject> <http://dbpedia.org/resource/Category:Banking> .
MINUS { ?page a dbo:Agent }
MINUS { ?page a dbo:WrittenWork }
}
This is like no filter is set:
WHERE
{
{
?page rdfs:label ?label .
?page a ?pageType .
?page <http://purl.org/dc/terms/subject> <http://dbpedia.org/resource/Category:Banking> .
MINUS { ?page a dbo:Agent, dbo:WrittenWork }
}
The question is:
what way should I go to exclude pages of certain types (direct and superclass)?

Answer 1

It look's like this is working answer (how to exclude multiple of types)
{
?page purl:subject ?id .
?page a ?pageType .
FILTER NOT EXISTS {
?page a/rdfs:subClassOf* ?skipClasses .
FILTER(?skipClasses in (dbo:Agent, dbo:Place, dbo:Work))
}
}
In this example all dbo:Agents, db:Places, dbo:Works will be filtered out.
