如何以编程方式重新配置 uima ruta 分析引擎（更改参数值）？

Question

这是问题的延续：

请指导我以编程方式重新配置分析引擎（通过更改参数值）。

Answer 1

情况：您有一个正确的 xml UIMA Ruta 分析引擎描述符，您想要重新配置，以便路径指向 descriptor.java url 文件的文件夹

下面的代码通过改变不同阶段的参数值来说明这一点。只需要一个阶段。哪一个适合您取决于您的代码。

package example;

import java.io.File;
import java.net.URL;

import org.apache.uima.analysis_engine.AnalysisEngine;
import org.apache.uima.analysis_engine.AnalysisEngineDescription;
import org.apache.uima.fit.factory.AnalysisEngineFactory;
import org.apache.uima.resource.metadata.ConfigurationParameterSettings;
import org.apache.uima.ruta.engine.RutaEngine;

public class ReconfigureExample {

  public static void main(String[] args) throws Exception {

    File file = new File("path to descriptor");
    String path = new File(file.toURI()).getParentFile().getAbsolutePath();
    String[] pathsArray = new String[] { path };

    // override the values in the descriptor when creating the description
    AnalysisEngineDescription desc = AnalysisEngineFactory.createEngineDescriptionFromPath(
            file.getAbsolutePath(), RutaEngine.PARAM_SCRIPT_PATHS, pathsArray,
            RutaEngine.PARAM_DESCRIPTOR_PATHS, pathsArray, RutaEngine.PARAM_RESOURCE_PATHS,
            pathsArray);

    // in case the location of the descriptor is not known...
    URL sourceUrl = desc.getSourceUrl();
    path = new File(sourceUrl.toURI()).getParentFile().getAbsolutePath();
    pathsArray = new String[] { path };

    // set the values in the description
    ConfigurationParameterSettings settings = desc.getAnalysisEngineMetaData()
            .getConfigurationParameterSettings();
    settings.setParameterValue(RutaEngine.PARAM_SCRIPT_PATHS, pathsArray);
    settings.setParameterValue(RutaEngine.PARAM_DESCRIPTOR_PATHS, pathsArray);
    settings.setParameterValue(RutaEngine.PARAM_RESOURCE_PATHS, pathsArray);

    // override the values in the descriptor when creating the analysis engine
    AnalysisEngine ae = AnalysisEngineFactory.createEngine(desc, RutaEngine.PARAM_SCRIPT_PATHS, pathsArray,
            RutaEngine.PARAM_DESCRIPTOR_PATHS, pathsArray, RutaEngine.PARAM_RESOURCE_PATHS,
            pathsArray);

    // set the values in the analysis engine and reconfigure it
    ae.setConfigParameterValue(RutaEngine.PARAM_SCRIPT_PATHS, pathsArray);
    ae.setConfigParameterValue(RutaEngine.PARAM_DESCRIPTOR_PATHS, pathsArray);
    ae.setConfigParameterValue(RutaEngine.PARAM_RESOURCE_PATHS, pathsArray);
    ae.reconfigure();

  }

}
