如果我想使用一个依赖于UIMA的库，我是否需要重写整个java项目？
我想在java项目中使用https://code.google.com/p/heideltime/ 。 该代码“适合UIMA管道”，这是我根本无法理解的。 UIMA看起来像是为了解决我没有的大量问题而设计的，所以我只想获得运行该代码所需的最小量的UIMA。
有一个简单的例子，我可以运行一个简单的UIMA程序吗？
我已经添加
org.uimafit uimafit 1.4.0 org.apache.uima uimaj-core 2.4.0 org.apache.uima uimaj-tools 2.4.0 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库更具实质性？ 仅仅从Maven Central中提取UIMA并开始在现有代码中使用它们的类是不够的？
好吧，我以某种方式让这个例子工作（我不知道它是什么，我仍然感到困惑，为什么它以前没有工作）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);
获得：

它在HeidelTime的主页上说
HeidelTime可作为UIMA注释器和独立版本使用。
有一个独立版本，我在这里 mavenized。 您应该能够破解de.unihd.dbs.heideltime.standalone.HeidelTimeStandalone.java的主要内容以满足您的需求。
