rdfsTranslator

This is a basic Ruby script which is translating simple sentences written in English to the RDF Schema file.

Installation Guide

To use this script you must have Ruby(was written using 2.1.1) installed on your computer. What is more, this script requires some gems to work properly. Here is the list of dependencies:

• active_support
• linguistics
• rspec and fakefs if you'd like to run tests

Usage

If your environment has everything installed and setup you have to run a basic command in your shell:

$ruby rdfst input_file.txt output_file.rdf

That's all... Now you have an output_file.rdf with schema on your disk!

Input and output

Input file is a text file with english sentences which you want to convert into RDF Schema. Each sentence should be in another line. Check out the example below:

Sudent is a human.
Student has name.
Teacher teaches student.
Teacher has an email.

And if your run rdfst on a file like this you'll get in result:

<?xml version='1.0'?>
<!DOCTYPE rdf:RDF [<!ENTITY rdf "http://www.w3.org/1999/02/22-rdf-syntax-ns#">]>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" 
         xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#">
