String textFile ="مدى اسبوع";
HeidelTimeStandalone H = new HeidelTimeStandalone(Language.ARABIC,
                DocumentType.NEWS,
                OutputType.TIMEML,
                "/heideltime-standalone/config.props",
                POSTagger.STANFORDPOSTAGGER,true);
        String result = H.process(textFile,resultFormatter );
        System.out.print(result);

as you can see the Processing aborted due to errors, would you please help me to fix the errors

Answer 1

The HeidelTime that function you're calling

String result = H.process(textFile,resultFormatter );

says in its doc comment:

/**
 * Processes document with HeidelTime
 * 
 * @param document
 * @return Annotated document
 * @throws DocumentCreationTimeMissingException
 *             If document creation time is missing when processing a
 *             document of type {@link DocumentType#NEWS}. Use
 *             {@link #process(String, Date)} instead to provide document
 *             creation time!
 */
public String process(String document, ResultFormatter resultFormatter)
        throws DocumentCreationTimeMissingException {

If you want to call this with NEWS then you'll have to specify a time too, as an extra parameter between the document and result formatter.
