public class ExtractorTest

extends Object

A simple command line demonstration of information extraction interfaced to the KAON Karlsruhe Ontology framework. This demo starts with an ontology, does extraction from a file, shows the results, and then writes to stdout a bigger ontology which additionally incorporates as instances things which have been extracted from the file. This RDF output is not very human readable.

Constructor Summary

ExtractorTest(String ontologyFilenameOrURL, String conceptName, File extractionDir)

Method Summary

void	extractFrom(String sourceText) Extract from the named file
static void	main(String[] args) Runs a simple demonstration of the extraction system.
void	storeRDF(PrintStream out)
