[NLP2RDF] Extending NIF Ontologies

[Carina Haupt]

Hi,

I am part of the OpenPHACTS project and it is my task to present 
textmining results in RDF. Therefore I am using the String as well as 
the SSO ontology of NIF. It allows me to represent most of my 
information, but unfortunately some predicates and classes are missing 
for my use case.
What I want to do is to represent not only the annotations made by the 
text mining tool, but also the texts they were found in, as well as the 
concepts which the annotations represent.
To represent the texts I use dc-term and to describe the concepts skos.

What I am missing is the connection between a concept and an annotation, 
as well as a type for the annotation itself. In my Institute (Fraunhofer 
SCAI), we call such an annotation a hit. To be able to complete my RDF 
schema I extended the ontology by adding pao:Hit and pao:incarnationOf 
(pao stands for Prominer Annotation Ontology and is based on SSO). 
pao:Hit thereby is a subclass of string:String and sso:incarnationOf 
needs a skos:Concept as domain and has pao:Hit as range.

Next to the text mining results I also store provenance information 
where I need to describe the used text mining tools. I think this use 
case is not covered by NIF so far, but should be suggested in further 
development. Im my case I added the class pao:Annotator and the 
predicate pao:annotatorClass.

I would like to hear your opinion to my suggestions and would like to be 
involved in the further development of your ontologies, since I think 
you are on the right way with them.

Best regards,
Carina
