DBpedia Mappings Wiki
In this DBpedia Mappings Wiki you can help to enhance the information in DBpedia. The DBpedia Extraction Framework uses the mappings defined here to homogenize information extracted from Wikipedia before generating structured information in RDF.
Anybody can help by editing:
- the DBpedia ontology schema (classes, properties, datatypes)
- the DBpedia infobox-to-ontology mappings
Mappings can be written for a variety of languages, connecting multiligual information to a language-independent unified ontology schema (language-specific labels can be provided there).
Mapping Example
This is how you write a simple infobox mapping.
Mapping:Infobox_actor
{{TemplateMapping
| mapToClass = Actor
| mappings =
{{ PropertyMapping | templateProperty = name | ontologyProperty = foaf:name }}
{{ PropertyMapping | templateProperty = birth_place | ontologyProperty = birthPlace }}
}}
This mapping extracts three information bits:
- the type information (Actor)
- the name of the actor
- the actor's place of birth.
Therefore, three RDF triples for each Infobox_actor in the English Wikipedia are extracted. For example for Vince Vaughn
dbpedia:Vince_Vaughn rdf:type dbpedia-owl:Actor . dbpedia:Vince_Vaughn foaf:name "Vince Vaughn"@en . dbpedia:Vince_Vaughn dbpedia-owl:birthPlace dbpedia:Minneapolis .
Detailed Information
- Check the Mapping Guide that defines the best practices for how to write clean, efficient mappings that extract lots of high-quality data
- Take a look at the Mapping Statistics to search for relevant infoboxes to map.
- How to edit the ontology schema
- How to edit infobox and table mappings
- Use the DBpedia Extraction Framework to extract structured data
Prerequisites
If you would like to edit the mappings or ontology schema this is what you need:
- a user account on this wiki (login/sign up)
- editor rights
- they will be given to you within a couple of days
- if not, please ask for editor rights at dbpedia-discussion@lists.sourceforge.net. Include your user name in the message.
- once you got editor rights, please provide some information about yourself on your user wiki page
- a namespace for the language you want to write mappings for
- if the namespace does not exist already (see the left side bar) please request it at dbpedia-discussion@lists.sourceforge.net
That's it!
That is all you need to kick-start. To get more detailed information, please follow the provided links.
Your contributions will be available
- in the DBpedia Live end point shortly after your edit (currently only for English)
- in the next DBpedia datasets release
Happy mapping!
