我想在 java 项目中使用https://code.google.com/p/heideltime/ 。该代码“适合 UIMA 管道”，这是我完全不理解的。UIMA 看起来它旨在解决我没有的大量问题，所以我只想获得运行该代码所需的最少量的 UIMA。
有没有一个简单的例子来说明我如何运行一个简单的 UIMA 程序？
我已经添加
<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>
到我的 pom.xml 但由于某种原因 maven 仍然不会编译这个：
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
UIMA 依赖项是否比典型的 java 库更重要？仅仅从 Maven Central 中提取 UIMA 并开始在我现有的代码中使用它们的类还不够吗？
好的，我以某种方式使这个示例正常工作（我不知道它是什么，并且仍然很困惑为什么它以前不工作）我仍然无法使用 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());
}
}
}
编辑 现在尝试：
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);
得到：
