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？ [英] Do I need to rewrite my entire java project if I want to use a single UIMA-dependent library?

问题描述

我想使用

HeidelTime可作为UIMA注释器使用独立版本。

我有一个独立版本这里。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。

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);

Getting:

解决方案

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.
