Hi Tim, the bits and pieces are available from
http://dbpedia.svn.sourceforge.net/viewvc/dbpedia/ontology/ the mappings themselves are available as Excel file mapping.xls and there is some documentation at http://dbpedia.svn.sourceforge.net/viewvc/dbpedia/ontology/docs/ The process we were using was to export the mapping from the xls into a relational database which is then used by the infobox extraction code to translate infobox property names to terms in the DBpedia ontology. The process as well as the mappings themselves are still far away from being optimal and we plan to design a proper RDF language to represent the mappings and implement a UI so that external contributors can help to update and extend the mappings. Due to a lack of resources this goes on slow but we hope to make some progress in the next months. Up-to-then, all we can offer are the bits and pieces listed above. Cheers Chris -----Ursprüngliche Nachricht----- Von: Tim Finin [mailto:[email protected]] Gesendet: Donnerstag, 9.

Is this available or the bits and pieces from which I can generate it? For example, I'd like to know that in some cases (e.g., for Barack_Obama) an infobox uses the string 'Born' and markup attribute 'birth_date' for a property that is represented in RDF as 'dbpedia-owl:birthdate' and also as 'dbpprop:dateOfBirth'. If I also knew the associated infobox template, I guess that might be helpful also. I am a little confused by the different dbpedia properties that are associated with some infobox attributes. for example Barack_Obama also has an RDF property 'dbpprop:birthDate' with value 'dbpedia:Barack_Obama/birthDate/birth_date_and_age'. What does this represent? I'm sorry that this is a bit vague. Ultimately, I am trying to enumerate possible ways of expressing different dbpedia-owl properties in text and I thought this might be a useful source of data to look at.
