I created a mapping between MeSH and DBpedia. The mapping is based on explicit mentions of MeSH entries that can be extracted Wikipedia/DBpedia. The preliminary result of this effort is a Turtle file with 2600 rdfs:seeAlso. It can be found at http://samwald.info/res/dbpedia_mesh_mapping.ttl The statements look like this: <http://dbpedia.org/resource/Primary_motor_cortex> rdfs:seeAlso <http://purl.org/commons/record/mesh/D009044> . I added the mapping to the HCLS Knowledge Base (http://hcls.deri.org/sparql ). It can be queried like this: ===== SELECT * WHERE { GRAPH <http://samwald.info/res/dbpedia_mesh_mapping.ttl> {?s ?p ?o} } LIMIT 10 ===== For example, this allows us to use the DBpedia-MeSH-PubMed connection to find PubMed abstracts that match a certain DBpedia entry. E.g, for http://dbpedia.org/resource/Primary_motor_cortex, we can query the HCLS Knowledge Base like this: ===== PREFIX dbpedia_uri: <http://dbpedia.org/resource/Primary_motor_cortex> PREFIX dc: <http://purl.org/dc/elements/1.1/> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> SELECT ?pubmed_uri WHERE { GRAPH <http://samwald.info/res/dbpedia_mesh_mapping.ttl> { dbpedia_uri: rdfs:seeAlso ?mesh_uri . } GRAPH <http://purl.org/science/graph/medline/subject-headings> { ?pubmed_uri ?o ?mesh_uri . } } LIMIT 5 ===== Result: http://purl.org/commons/record/pmid/4319929 http://purl.org/commons/record/pmid/4951845 http://purl.org/commons/record/pmid/6015242 http://purl.org/commons/record/pmid/4999957 http://purl.org/commons/record/pmid/5633926 [...] Further documentation and a link to the PHP script that was used to generate the mapping: http://esw.w3.org/topic/HCLSIG_BioRDF_Subgroup/DBpedia_to_OBO_mapping I hope this is helpful to some people reading this list.
