What is Stanbol?
Stanbol is an application that in simple words allow to obtain aditional information from a document.
For example, if I have a text who talk about the Romans emperors and I pass it through Stanbol, it will infer the language of the text (e.g. English) and the entities present in the text (Rome, Ceasar, Italy, Neron, etc), . With entities we refer to places and persons.

For example, for the text:
Argentina is a big country in South America
Stanbol detect the follow entities:
It found two entities of the “place” type “argentina” and “south America” and it found the language of the text “english”
You can receive the same information through command line with curl:
curl -X POST -H "Content-type: text/plain" --data "Argentina is a big country in South America." \ http://localhost:8080/enhancer

If you have a file “text.txt” in your current folder, with this command line you can upload the file to get the enhanced information:
curl -X POST -H "Content-type: text/plain" -T text.txt \ http://localhost:8080/enhancer
