###Reasoning over the Gene Ontology with the Biomodels database

the following query will count all the biochemical reactions in the biomodels database that are involved in "protein catabolic process". It works first by getting all the biochemical reactions labelled with that GO term (using the bioportal endpoint), and joining these results with all the biochemical reactions that are annotated with GO terms that are more specific than "protein catabolic process"

SELECT ?go ?label count(distinct ?x)
WHERE {
   { 
    # get all the biochemical reactions specifically labelled with protein catabolic process
    ?go rdfs:label ?label .
    FILTER regex(?label, "^protein catabolic process")
    service <http://biomodels.bio2rdf.org/sparql> {
     ?x <http://bio2rdf.org/biopax_vocabulary:identical-to> ?go . 
     ?x a <http://www.biopax.org/release/biopax-level3.owl#BiochemicalReaction> .
    } # end service

   } UNION {
    # get all the biochemical reactions that are more specific than "protein catabolic process"
    ?go rdfs:label ?label .
    ?go rdfs:subClassOf ?tgo OPTION (TRANSITIVE) . # get all the subclasses of the target to term
    ?tgo rdfs:label ?tlabel .
    FILTER regex(?tlabel, "^protein catabolic process")
    service <http://biomodels.bio2rdf.org/sparql> {
     ?x <http://bio2rdf.org/biopax_vocabulary:identical-to> ?go . 
     ?x a <http://www.biopax.org/release/biopax-level3.owl#BiochemicalReaction> .
    } # end service
   } # end union
} # end where

The following is an alternative version of the previous query that does not make use of rdfs:label to find go terms that share the "protein catabolic process" (GO:0030163) term.

SELECT ?go ?label count(distinct ?x)
WHERE {
   { 
    ?go rdfs:label ?label .
    FILTER (?go = <http://bio2rdf.org/go:0030163>)
    service <http://biomodels.bio2rdf.org/sparql> {
     ?x <http://bio2rdf.org/biopax_vocabulary:identical-to> ?go . 
     ?x a <http://www.biopax.org/release/biopax-level3.owl#BiochemicalReaction> .
    } 
} UNION {
    ?go rdfs:label ?label .
    ?go rdfs:subClassOf ?tgo OPTION (TRANSITIVE) . 
    FILTER (?tgo = <http://bio2rdf.org/go:0030163>)
    service <http://biomodels.bio2rdf.org/sparql> {
     ?x <http://bio2rdf.org/biopax_vocabulary:identical-to> ?go . 
     ?x a <http://www.biopax.org/release/biopax-level3.owl#BiochemicalReaction> .
    } 
   }
} 

Evaluating the disparity between the amount of research and burden of disease

This SPARQL query utilizes 3 datasets: PubMed, GHO and LinkedCT (only PubMed belonging to Bio2RDF). This SPARQL query can be executed on this endpoint: http://db0.aksw.org:8895/sparql

This query counts the number of distinct publications and number of distinct deaths due to the disease Tuberculosis in the country India.
