machine-learning - Cleartk:初始化[class org.cleartk.classifier.jar.DefaultSequenceDataWriterFactory]时出错，必填字段'dataWriterClassName'

我的主程序如下所示：

    public static void main(String args[]) throws UIMAException, IOException{
    //TypeSystemDescription tsd = TypeSystemDescriptionFactory.createTypeSystemDescription(Question.class);

    AggregateBuilder builder = new AggregateBuilder();
    //builder.add(SentenceAnnotator.getDescription());
    builder.add(AnalysisEngineFactory.createPrimitiveDescription(POSAnnotator1.class,
            ExampleComponents.TYPE_SYSTEM_DESCRIPTION,
            GenericJarClassifierFactory.PARAM_CLASSIFIER_JAR_PATH, outputDirectory + File.separator + "model.jar",
            CleartkAnnotator.PARAM_IS_TRAINING, true,
            DefaultDataWriterFactory.PARAM_DATA_WRITER_CLASS_NAME, InstanceDataWriter.class.getName(),
            DirectoryDataWriterFactory.PARAM_OUTPUT_DIRECTORY, new File(outputDirectory)));

    JCas jcas = JCasFactory.createJCas();
    jcas.setDocumentText(testData);

    SimplePipeline.runPipeline(jcas, builder.createAggregateDescription());

}

谁能解释这个错误？


  引起原因：java.lang.IllegalArgumentException：初始化[class org.cleartk.classifier.jar.DefaultSequenceDataWriterFactory]时出错
  字段“ dataWriterClassName”为必填项


我试图用其他数据编写器替换InstanceDataWriter，但是它们不起作用。

最佳答案

POS注释器使用序列数据编写器编写示例。您可以从DefaultDataWriterFactory.PARAM_DATA_WRITER_CLASS_NAME设置DataWriter类名Parameter。对于序列数据写入器，它应该是DefaultSequenceDataWriterFactory.PARAM_DATA_WRITER_CLASS_NAME。序列意味着在cas（许多POS标签）中有超过1个标签，而“普通”分类器则为整个文档仅提供1个标签。
