i want to get data with sparql from Medical Subject Headings RDF
i try to do this code :
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
PREFIX owl: <http://www.w3.org/2002/07/owl#>
PREFIX meshv: <http://id.nlm.nih.gov/mesh/vocab#>

SELECT DISTINCT ?descriptor ?label

WHERE {

?childTreeNum meshv:parentTreeNumber+ ?treeNum .
?descriptor meshv:treeNumber ?childTreeNum .
?descriptor rdfs:label ?label .
}
ORDER BY ?label
this code return
descriptor label
mesh:D000182 ACTH Syndrome, Ectopic
mesh:D049913 ACTH-Secreting Pituitary Adenoma
mesh:D000008 Abdominal Neoplasms
but me i want to get from this page for example https://meshb.nlm.nih.gov/record/ui?ui=D000172 :
Musculoskeletal Diseases [C05]
Bone Diseases [C05.116]
Bone Diseases, Endocrine [C05.116.132]
Acromegaly [C05.116.132.082]
Congenital Hypothyroidism [C05.116.132.256]
.........
but i want to collect all data (code with label) from mesh, not only this example
I know I'm not answering your question, but you are missing the rdfs prefix in the beginning...

I am using Apache Jena Fuseki Server for Storing Geo Coordinates of location. How to find out that if two polygons or two rectangles intersect each other inside Fuseki. Please share links related to it if possible. Thank you.
Hello...I am just updating question based on the below comments. Please suggest me regarding the problem I am facing. I have stored geocoordinates in WKT serialization format. When I execute below query
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>

SELECT ?object
WHERE {

} }
I get these below results.

Then later I want to filter out these geo:WKT objects based on geo:intersection (Intersection or equals or contains methods). And I updated my query as below.
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX geo: <http://www.opengis.net/ont/geosparql#>

PREFIX : <http://example.org/#>
PREFIX geo: <http://www.opengis.net/ont/geosparql#>
PREFIX spatial: <http://jena.apache.org/spatial#>
SELECT ?object
WHERE {
GRAPH <http://project/base/default> {
?subject geo:asWKT ?object .
?object geo:equals "POLYGON((8.463699817657472 48.99872928913063,8.463887572288515 48.998644821906865,8.46399486064911 48.998764483764916,8.46425771713257 48.99865538031766,8.464375734329225 48.998746886450874,8.463919758796694 48.99893693711346,8.463699817657472 48.99872928913063))"
} }
Which should result me atleast the coordinates of first geo object which really equals the POLYGON coordinates but I get empty results as shown in below image. Please suggest me where I am getting it wrong.
I have a problem, which I explain on following example:
I want to retrieve all information in any language on a category. I must use ?category as a label and the language labels en, as they are inputs in my program.
The query looks like this, but when I change the language I don't receive any information on the category. I know the problem lies in the dcterms:subject, because ?category returns http://dbpedia.org/resource/Category:Countries_in_Europe (see first example below).
For example to search for a category label in german you have to use http://de.dbpedia.org/resource/Kategorie:Staat_in_Europa (see second example below).
prefix dcterms: <http://purl.org/dc/terms/>
prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT DISTINCT ?objectLabel WHERE {
?subject dcterms:subject ?category ; rdfs:label ?objectLabel
?category rdfs:label "Countries in Europe"#en .
FILTER (LANG(?objectLabel)='en')
}
Equivalent query in different language that doesn't work as example:
prefix dcterms: <http://purl.org/dc/terms/>
prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT DISTINCT ?objectLabel WHERE {
?subject dcterms:subject ?category ; rdfs:label ?objectLabel
?category rdfs:label "Staat in Europa"#de .
FILTER (LANG(?objectLabel)='de')
}
Is there a similar or different way / method to solve the problem? Thanks in advance for any help.
This question already has answers here:
Why is dbpedia-owl:wikiPageRedirects not returning the full set of redirect links? (Sparql)
(2 answers)
Closed 7 years ago.
I wanted to get the "is dbo:wikiPageRedirects of" and use it as an alias to the label.
ex:
PREFIX owl: <http://www.w3.org/2002/07/owl#>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX dc: <http://purl.org/dc/elements/1.1/>
PREFIX dbo: <http://dbpedia.org/ontology/>
PREFIX : <http://dbpedia.org/resource/>
PREFIX dbpedia2: <http://dbpedia.org/property/>
PREFIX dbpedia: <http://dbpedia.org/>
PREFIX skos: <http://www.w3.org/2004/02/skos/core#>
SELECT *
WHERE {
FILTER (?uri = <http://dbpedia.org/resource/Benigno_Aquino_III>)
OPTIONAL{
?uri rdfs:label ?label .
FILTER( LANG(?label) = "" || LANGMATCHES(LANG(?label), "en") )
}
OPTIONAL
{
?uri dbo:birthDate ?birthDate .
}
OPTIONAL
{
?uri rdfs:label "Benigno Aquino III"#en ;
dbo:wikiPageRedirects ?redirectsTo .
}
}
what I get is a blank wikiPageRedirects, But when i use http://dbpedia.org/resource/PNOY i get http://dbpedia.org/resource/Benigno_Aquino_III as redirectsTo. I want to do the opposite.
The relation is "dbo:wikiPageRedirects of" and not "dbo:wikiPageRedirects". In this case, it means that http://dbpedia.org/resource/Benigno_Aquino_III lists the resources which have a connection of the sort
?u dbo:wikiPageRedirects http://dbpedia.org/resource/Benigno_Aquino_III
you should use
?redirectsTo dbo:wikiPageRedirects ?uri .
I am a biology trying to understand the meaning of a triple from this SPARQL query. If "a" is a triple, what are the resources for subject, object and predicate in this sample query?

atlasterms:propertyValue ?propertyValue]

]
filter regex (?description, "diabetes", "i")
}
I appreciate your help?
Thanks,
AD
?experiment
a atlasterms:Experiment ;
is the same as
?experiment a atlasterms:Experiment ;
is the same as
?experiment rdf:type atlasterms:Experiment ;
so the form in the query is just a whitespace rearrangement and using the built-in abbreviation "a" for property rdf:type.
See http://www.sparql.org/query-validator.html for an online formatter of SPARQL queries.
A simpler query is:
SELECT DISTINCT ?experiment ?description
WHERE
{ ?experiment rdf:type atlasterms:Experiment .
?experiment dcterms:description ?description
FILTER regex(?description, "diabetes", "i")
}
because
SELECT DISTINCT ?experiment ?description
means that the ?propertyType/?propertyValue part is not affecting the outcome.
