	<h1>NLP2RDF demo</h1>
This web site show cases the available nif webservices.
Note that the list displayed here is not complete. 
More tools will be added here: <a href="http://nlp2rdf.org/implementations"> http://nlp2rdf.org/implementations</a> 
or in the <a href="http://code.google.com/p/nlp2rdf/source/browse/#hg%2Fimplementation"> NLP2RDF Google Code</a> repository. 
The code for this demo is available <a href="http://code.google.com/p/nlp2rdf/source/browse/nlp2rdf.lod2.eu/demo.php">here</a>.
<!--The server that hosts the services is really slow. (We measured it and some of our laptops are 30 times faster than the server).-->
