Help:WikiPathways SPARQL queries
From WikiPathways
On http://sparql.wikipathways.org/ WikiPathways content is replicated in a SPARQL endpoint. Queries can be performed in three ways:
1. Either go to the endpoint directly and create your own SPARQL query.
2. Copy and paste an example query listed below in the endpoint.
3. Adapt a code examples to programmatically make a SPARQL query
This project is written up in the "Using the Semantic Web for Rapid Integration of WikiPathways with Other Biological Online Data Resources" paper.

Prefixes
Within the example queries, we have omitted the prefixes. These prefixes are automatically used in the SPARQL endpoint. The following prefixes are used in the WikiPathways RDF:

Count the number of pathways per ontology term
In WikiPathways, pathways can be tagged with ontology terms from Pathway, Cell Line and Disease ontology. The following query returns a pathway count for each term from any of the available ontologies. These terms are collectively modeled as wp:pathwayOntology; but this includes all ontologies, not just the "Pathway" ontology.
SELECT DISTINCT ?pwOntologyTerm count(?pwOntologyTerm) as ?pathwayCount
WHERE {
?pathwayRDF wp:ontologyTag ?pwOntologyTerm .
}
ORDER BY DESC(?pathwayCount)
Get all pathways with a particular ontology term
In WikiPathways, pathways can be tagged with ontology terms from Pathway, Cell Line and Disease ontology. The following query returns a list of pathways tagged with PW_0000296.
PREFIX obo: <http://purl.obolibrary.org/obo/>
SELECT ?pathway (str(?titleLit) AS ?title)
WHERE {
?pathwayRDF wp:ontologyTag obo:PW_0000296 ;

Get all Proteins from Community pathways
Obtain all Protein DataNodes (so not GeneProducts) from specific communities. Note: All community tags are available in the WikiPathways SPARQL endpoint now (the "Blau" community was updated to "IEM").

Get all pathways with PubMed references

WHERE {

?pubmed dcterms:isPartOf ?pathway .
FILTER regex(str(?pubmed), "14769483$")
}
ORDER BY ?pathway
The $ at the end of the PubMed identifier ensures that, for example, 147694831 does not match too; the regex instruction '$' means "end of the string".
Get all pathways and the number of refences per pathway
SELECT DISTINCT ?pathway COUNT(?pubmed) AS ?numberOfReferences
WHERE

?pubmed dcterms:isPartOf ?pathway }

Count how many genes from a list occur in one or more pathways
The gene list is given in the line starting with VALUES. For this example, we use the HGNC gene nomenclature.
Other gene IDs can be used to fill the list. However, keep in mind they use different URLs and therefore the prefix (first line of query) should be adapted. A list of these URLs can be found on identifiers.org (or by looking at the "raw" RDF files).

Data statistics oriented queries
Count the number of metabolites per species
Though strictly speaking, it guesstimates it, because it counts the number of unique metabolite identifiers. Normalization in the RDF generation code ensures we do not double count metabolites with identifiers from different databases, but it still differentially counts metabolites with different charge states.

That mostly lists gene identifier sources, etc, but watch out for the metabolite identifier data sources. For example, metabolites not marked as such but with a metabolite identifier can be found this way. Down the list is CAS (but genes are chemicals too...), and a few minor more:
HMDB 4 ChEBI 3 GLYCAN 3 COMPOUND 3 PubChem 2
I would expect GLYCAN and COMPOUND to be misnomers of the matching KEGG subsets.
Metabolites sometimes marked as DataNode@Type Metabolite
Based on label comparisons, we can find things that are labeled the same as a data node with the same label. Of course, this can give false positives, because genes can be incorrectly marked as metabolite in some pathway, but that is another SPARQL query. Another reasons is that sometimes genes and metabolites actually have the same name!

Metabolites with too many labels
This query can result in false positives too, particularly with the new RDF.

} order by desc(?labelCount) ?mb
And get the actual labels (and more) with:
describe <https://identifiers.org/hmdb/HMDB0002174>
Or use this one, but mind that pathway/label combinations are combinatorial, because they share the same node:
select distinct ?pathway (str(?labelLit) as ?label)

Code examples
Perl
There is an RDF api available. Below is an example that extracts the data by converting the query into a url and extracts the data as CSV.
#!/usr/bin/perl
use LWP::Simple;
use URI::Escape;
my $sparql = "SELECT DISTINCT ?wpIdentifier ?elementneedsattention ?elementLabel

ORDER BY ?wpIdentifier";
my $url = 'https://sparql.wikipathways.org/sparql?default-graph-uri=&query='.uri_escape($sparql).'&format=text%2Fcsv&timeout=0&debug=on';
my $content = get $url;
die "Couldn't get $url" unless defined $content;
print $content;
Java
For java we recommend the Jena Framework.
import com.hp.hpl.jena.query.Query;
import com.hp.hpl.jena.query.QueryExecution;
import com.hp.hpl.jena.query.QueryExecutionFactory;
import com.hp.hpl.jena.query.QueryFactory;
import com.hp.hpl.jena.query.QuerySolution;
import com.hp.hpl.jena.query.ResultSet;
public class javaCodeExample {
public static void main(String[] args) {
String sparqlQueryString = "SELECT * WHERE {?s ?p ?o} LIMIT 10";
Query query = QueryFactory.create(sparqlQueryString);
QueryExecution queryExecution = QueryExecutionFactory.sparqlService("https://sparql.wikipathways.org/sparql", query);
ResultSet resultSet = queryExecution.execSelect();
while (resultSet.hasNext()) {
QuerySolution solution = resultSet.next();
System.out.print(solution.get("s"));
System.out.print("\t"+solution.get("p"));
System.out.println("\t"+solution.get("o"));
}
}
}
php
For php we recommend the arc2: Easy RDF and SPARQL for LAMP systems
R
The R package rrdf can be found and installed from https://github.com/egonw/rrdf.
library(rrdf)
sparql.remote(
"https://sparql.wikipathways.org/sparql",
"SELECT DISTINCT ?p WHERE { ?s ?p ?o }"
)
Another option is to use the SPARQL-package (tested on Ubuntu 18.04.5 LTS, R-studio version 1.4.1717, R version 4.1.0 (2021-05-18)).
- Note the backslashes in front of the quotation marks in the VALUES claim; this is specifically needed in R to read these characters correctly.
- Note this query is an example of how to perform a UNION query in WikiPathways.
if(!"SPARQL" %in% installed.packages()){
install.packages("SPARQL")

Bioclipse
The below code works in both the JavaScript and the Groovy console:
rdf.sparqlRemote(
"https://sparql.wikipathways.org/sparql",
"SELECT DISTINCT ?p WHERE { ?s ?p ?o }"
)
SPARQL from the command line
For quick and easy querying, we recommend to use curl (Linux and OS X)
curl -F "query=SELECT * WHERE {?s ?p ?o} LIMIT 10" https://sparql.wikipathways.org/sparql
