Hi Tharindu As Rafa suggested you should generate fise:TextAnnotation [1]. You can use "http://dbpedia.org/ontology/Currency"; as "dc:type" for the fise:TextAnnotation.
If you engine can detect the currency and the value you should add those information by using additional properties to the annotation. There are already some ontologies that define such properties. I would suggest to use GoodReleations [2] 'gr:hasCurrency' and 'gr:hasCurrencyValue' properties. But there are also other possibilities such as schema.org PriceSpecification [3] defines 'schema:price' and 'schema:priceCurrency' properties. If would be also possible to define Stanbol specific 'fise:currency' and 'fise:currency-value' properties. Finally it could make sense that the Engine does not use the String codes for referring the currency but the dbpedia resource instead (e.g. <http://dbpedia.org/resource/Euro> instead of "EUR"). In that case fise:TextAnnotation could have properties for both the resource and the code e.g. <urn:example:textannotation.1> rdf:type fise:Enhancement, fise:TextAnnotation dc:type dbo:Currency fise:selected-text "100€"@en fise:start "150"^^xsd:int fise:end "154"^^xsd:int fise:selection-context "I had to spend additional 100€ just to arrive in time"@en fise:confidence "0.92"^^xsd:double fise:currency <http://dbpedia.org/resource/Euro> fise:currency-code "EUR" fise:currency-value "100.0"^^xsd:double BTW we should start an JIRA issue [4] for such an EnhancementEngine and use it to collect/document the discussions. best Rupert [1] http://stanbol.apache.org/docs/trunk/components/enhancer/enhancementstructure.html#fisetextannotation [2] http://semanticweb.org/wiki/GoodRelations [3] http://schema.org/PriceSpecification [4] https://issues.apache.org/jira/browse/STANBOL On Thu, Feb 13, 2014 at 5:23 PM, Rafa Haro <rh...@apache.org> wrote: > Hi Tharindu, > > Probably you would need to use a custom type for Currencies' Text > Annotations.
