GERBIL integration for the evaluation

The following is an example of a cURL POST request that GERBIL performs to an annotation system.
The URL http://system_end_point should be replaced with the actual publicly accessible URL of the system.
The NIF-compliant turtle provided as input contains the sentence to be annotated.

curl -H "Content-Type:application/x-turtle" -H "Accept:application/x-turtle" 
  -d "@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .

              a                     nif:RFC5147String , nif:String , nif:Context ;
              nif:beginIndex        \"0\"^^xsd:nonNegativeInteger ;
              nif:endIndex          \"146\"^^xsd:nonNegativeInteger ;
              nif:isString          \"Florence May Harding studied at a school in Sydney, and with Douglas Robert Dundas , but in effect had no formal training in either botany or art.\"@en ."

An annotation system should produce a valid NIF-compliant turtle as output. Such a turtle contains the annotations produced by an annotation system, cf. https://github.com/anuzzolese/oke-challenge-2016/blob/master/example_data/task1.ttl for details.

So the participants to the challenge should take care that their systems:

  • expose REST interface compliant with the cURL example above;
  • produce NIF-compliant outputs for their annotations.
