Rupert Westenthaler commented on STANBOL-335:
---------------------------------------------
As a first step let me describe what properties are currently included within
the Indices created for entity extraction (NamedEntityTaggingEngine and
KeywordLinkingEngine) as well as the user interface of the Stanbol Enhancer.
### CORE properties
* rdfs;label (in all languages)
* rdfs:comment (only in english)
* rdf:type
* rdfs:seeAlso (however I think this property is not used by DBpedia)
* dbp-ont:wikiPageRedirects mapped to rdfs:seeAlso
### SPATIAL properties:
* geo:lat
* geo:long
* geo:alt
* dbp-ont:elevation is mapped to geo:alt and values are converted to xsd:int
### CATEGORY properties:
**Category assignment**
* dc-terms:subject (because it is used to store the participation of Entities
in Categories)
* dc-elements:subject is mapped to dc-terms:subject
**Category data**
* skos:* (all skos properties - such properties are only used for categories)
* skos:prefLabel is copied to rdfs:label
* skos:altLabel is copied to rdfs:label
* skos:hiddenLabel is copied to rdfs:label
* skos:relatedMatch is copied to skos:related
* skos:broadMatch is copied to skos:broader
* skos:narrowMatch is copied to skos:skos:narrower
* skos:narrowerTransitive is copied to skos:narrower
* skos:broaderTransitive is copied to skos:broader
** OTHER properties **
* foaf:homepage (link to the homepage of the entity)
* foaf:depiction (link to the thumbnail)
* dbp-ont:thumbnail is mapped to foaf:depiction (because this property is also
used for thumbnails)
* dbp-ont:birthDate
* dbp-ont:deathDate
* dbp-ont:populationTotal
This configuration creates an Index of about 5GByte when including 4.4 million
entities.
