org.nlp2rdf.core.impl
Class MD5Based

java.lang.Object
  org.nlp2rdf.core.impl.AbstractURIGenerator
      org.nlp2rdf.core.impl.MD5Based

All Implemented Interfaces:

URIGenerator

public class MD5Based
extends AbstractURIGenerator
implements URIGenerator

Author:

Sebastian Hellmann - http://bis.informatik.uni-leipzig.de/SebastianHellmann

This class implements the NIF Context-hash URI recipe. Before creating URIs init should be called, because this sets the correct value for contextLength

There is no reason, why this would be threaded, so it is not threadsafe

Field Summary

static String	bra
static String	identifier
static String	ket

Constructor Summary

MD5Based()

Method Summary

void	assignRecipeClass(String uri, com.hp.hpl.jena.ontology.OntModel model) adds an rdf:type statement to model for the respective recipe
String	getRecipeUri() This returns the recipe class form the String ontology: http://nlp2rdf.lod2.eu/schema/string/
opennlp.tools.util.Span	getSpanFor(String prefix, String uri, String text, String anchoredPart)
void	init(String text, Set<opennlp.tools.util.Span> spans)
String	makeUri(String prefix, String text, opennlp.tools.util.Span span) Depending on the implementation, it might be necessary to call init before calling this function
