java - 如果我想使用单个 UIMA 依赖库，是否需要重写整个 java 项目？

Question

我想使用https://code.google.com/p/heideltime/在一个java项目中。该代码“适合 UIMA 管道”，这是我根本不理解的。 UIMA 看起来是为了解决大量我没有的问题而设计的，所以我只想获得运行该代码所需的最少量的 UIMA。

是否有一个简单的示例来说明如何运行简单的 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？仅从 Maven Central 提取 UIMA 并开始在我现有的代码中使用它们的类还不够吗？

好吧，我以某种方式让这个例子工作了(我不知道它是什么，并且仍然困惑为什么它之前不起作用)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());
        }   

    }
}

编辑现在正在尝试:

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);

获取:

上面写着HeidelTime's homepage

HeidelTime is available as UIMA annotator and as standalone version.

我有一个独立版本 here 。你应该能够破解de.unihd.dbs.heideltime.standalone.HeidelTimeStandalone.java主要是为了满足您的需求。
