Originating from the Latin Documentum meaning lesson - the verb means to teach, and is pronounced similarly, in the past it was usually used as a term for a written proof used as evidence."}' http://localhost:7474/service/graphify/classify
####Get a list of the extracted semantic features matching a text:
curl -H "Content-Type: application/json" -d '{"text": "A document is a written or drawn representation of thoughts. Originating from the Latin Documentum meaning lesson - the verb means to teach, and is pronounced similarly, in the past it was usually used as a term for a written proof used as evidence."}' http://localhost:7474/service/graphify/extractfeatures
