如果要使用一个依赖于UIMA的库，是否需要重写整个java项目？

Question

我想在java项目中使用https://code.google.com/p/heideltime/。该代码“符合UIMA管道”，这一点我完全不明白。UIMA看起来好像是为了解决很多我没有的问题而设计的，所以我只想得到运行该代码所需的最小数量的UIMA。

有没有一个简单的例子说明我如何运行一个简单的UIMA程序？

我增加了

    <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>

但出于某种原因，maven仍然不会编译以下内容：

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依赖关系是否比典型的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，我以某种方式让这个例子起了作用(我不知道它是什么，并且仍然不明白为什么它以前不起作用)，我仍然不能使用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：

上面写着HeidelTime主页

HeidelTime可以作为UIMA注解器和独立版本使用。

有一个独立的版本，我已经把这里混在一起了。您应该能够破解de.unihd.dbs.heideltime.standalone.HeidelTimeStandalone.java的主程序，以满足您的需要。
