I want to use https://code.google.com/p/heideltime/ in a java project. That code "fits into the UIMA pipeline", which is something I don't understand at all. UIMA looks like it's designed to solve a ton of problems that I don't have, so I'd just like to get the minimal amount of UIMA needed to run that code.
Is there a simple example out there of how I can run a simple UIMA program?
I've added
<dependency>
<groupId>org.uimafit</groupId>
<artifactId>uimafit</artifactId>
<version>1.4.0</version>
</dependency>
<dependency>
<groupId>org.apache.uima</groupId>
<artifactId>uimaj-core</artifactId>
<version>2.4.0</version>
</dependency>
<dependency>
<groupId>org.apache.uima</groupId>
<artifactId>uimaj-tools</artifactId>
<version>2.4.0</version>
</dependency>
to my pom.xml but for some reason maven still won't compile this:
import org.apache.uima.jcas.JCas;
import org.apache.uima.util.Level;
import org.uimafit.component.JCasAnnotator_ImplBase;
import org.uimafit.descriptor.ConfigurationParameter;
import org.uimafit.descriptor.TypeCapability;
import org.uimafit.examples.tutorial.type.RoomNumber;
public class RoomNumberAnnotatorPipeline {
public static void main(String[] args) throws Exception {
String text = "The meeting was moved from Yorktown 01-144 to Hawthorne 1S-W33.";
TypeSystemDescription tsd = createTypeSystemDescription( "org.uimafit.examples.tutorial.type.RoomNumber");
JCas jCas = createJCas(tsd);
// jCas.setDocumentText(text);
// AnalysisEngine analysisEngine = createPrimitive(RoomNumberAnnotator.class, tsd);
// analysisEngine.process(jCas);
//
// for (RoomNumber roomNumber : select(jCas, RoomNumber.class)) {
// System.out.println(roomNumber.getCoveredText() + "\tbuilding = "
// + roomNumber.getBuilding());
// }
}
}
[ERROR] symbol : class TypeSystemDescription
[ERROR] location: class com.stackoverflow.RoomNumberAnnotatorPipeline
Are UIMA dependencies somehow more substantial than a typical java library? Is it not enough to just pull UIMA from Maven Central and start using their classes in my existing code?
ok, I somehow got this example working (I have no idea what it is, and am still confused why it was not working before) I am still not able to use heideltime:
package org.ryan;
import static org.uimafit.factory.AnalysisEngineFactory.createPrimitive;
import static org.uimafit.factory.JCasFactory.createJCas;
import static org.uimafit.factory.TypeSystemDescriptionFactory.createTypeSystemDescription;
import static org.uimafit.util.JCasUtil.select;
import org.apache.uima.UIMAException;
import org.apache.uima.analysis_engine.AnalysisEngine;
import org.apache.uima.jcas.JCas;
import org.apache.uima.resource.metadata.TypeSystemDescription;
import org.uimafit.examples.tutorial.ex1.RoomNumberAnnotator;
import org.uimafit.examples.tutorial.type.RoomNumber;
/**
* Hello world!
*
*/
public class UIMAWTF
{
public static void main( String[] args ) throws UIMAException
{
String text = "The meeting was moved from Yorktown 01-144 to Hawthorne 1S-W33. Today is May 5, 2013.";
TypeSystemDescription tsd = createTypeSystemDescription("org.uimafit.examples.tutorial.type.RoomNumber");
JCas jCas = createJCas(tsd);
jCas.setDocumentText(text);
AnalysisEngine analysisEngine = createPrimitive(RoomNumberAnnotator.class, tsd);
analysisEngine.process(jCas);
for (RoomNumber roomNumber : select(jCas, RoomNumber.class)) {
System.out.println(roomNumber.getCoveredText() + "\tbuilding = "
+ roomNumber.getBuilding());
}
}
}
edit Now trying:
HeidelTimeStandalone hts_sci = new HeidelTimeStandalone(Language.ENGLISH, DocumentType.NEWS, OutputType.TIMEML);//, configPath);
dates = hts_sci.process("19-Nov-2013", new Date(2012,01,05), new TimeMLResultFormatter());
System.out.println(dates);

It says on HeidelTime's homepage
HeidelTime is available as UIMA annotator and as standalone version.
There is a standalone version that I mavenized here. You should be able to hack de.unihd.dbs.heideltime.standalone.HeidelTimeStandalone.java's main to fit you needs.
